Missing artifact com sun tools jar

Question

I ve been following the getting started tutorial  but am stuck after I imported the playn project using Maven   I am using Eclipse Indigo running on 64bit Windows 7   All the imported projects have the same error   Missing Artifact com sun tools jar in all the pom xml files    After a couple hours of searching forums I have tried   Installing the latest Java 1 6 029 Changing my JAVA HOME environment variable to point to  program files Java jdk1 6 029 Changing my Eclipse Java preferences to use the JRE jdk1 6 029   I would really like to experiment with playn  but why there are a few posts I can t seem to find a consenus answer on the solution    Some people say Sun removed something from the 64bit jdk  others say you must edit your xml files  many people have said you have change your JAVA HOME  and another said you have to change your VM options for Eclipse   Any help on clearing this up would be appreciated  and possibly useful for many  since I do not have a particularly odd setup here    edit  Here is the pom xml in the first project   Eclipse flags error in the line which says    lt project xmlns  http   maven apache org POM 4 0 0  xmlns xsi  http   www w3 org 2001 XMLSchema-instance  xsi schemaLocation  http   maven apache org POM 4 0 0 http   maven apache org maven-v4 0 0 xsd  gt     lt modelVersion gt 4 0 0 lt  modelVersion gt      lt parent gt       lt groupId gt com googlecode playn lt  groupId gt       lt artifactId gt playn-project lt  artifactId gt       lt version gt 1 1-SNAPSHOT lt  version gt     lt  parent gt      lt artifactId gt playn-android lt  artifactId gt     lt name gt PlayN Android lt  name gt     lt packaging gt jar lt  packaging gt      lt repositories gt     lt  repositories gt      lt dependencies gt       lt dependency gt         lt groupId gt com googlecode playn lt  groupId gt         lt artifactId gt playn-core lt  artifactId gt         lt version gt   project version  lt  version gt       lt  dependency gt        lt  -- needed because Android uses the same JSON code as playn-java           that should be factored into a library shared by both backends -- gt       lt dependency gt         lt groupId gt com googlecode playn lt  groupId gt         lt artifactId gt playn-java lt  artifactId gt         lt version gt   project version  lt  version gt       lt  dependency gt        lt dependency gt         lt groupId gt com google android lt  groupId gt         lt artifactId gt android lt  artifactId gt         lt version gt   android version  lt  version gt         lt scope gt provided lt  scope gt       lt  dependency gt        lt dependency gt         lt groupId gt junit lt  groupId gt         lt artifactId gt junit lt  artifactId gt         lt version gt 4 8 1 lt  version gt         lt scope gt test lt  scope gt       lt  dependency gt     lt  dependencies gt      lt build gt       lt sourceDirectory gt src lt  sourceDirectory gt     lt  build gt   lt  project gt

As other posters have stated the issue here has to do with the JRE that eclipse is using not being able to find the tools jar. I solved the issue by going in a bit of a different direction than what was stated above, and it was because of the way that my projects and environment.

Eclipse 4.5 requires at least Java 7 for runtime, so I've got my system setup to use a Java 8 JRE located at C:\java\jre1.8.0_45.

Next, I'm using a POM file that assumes that I'm running with a Java 6 JDK.

  <profiles>
    <profile>
      <id>default-profile</id>
      <activation>
        <activeByDefault>true</activeByDefault>
        <file>
          <exists>${java.home}/../lib/tools.jar</exists>
        </file>
      </activation>
      <properties>
        <toolsjar>${java.home}/../lib/tools.jar</toolsjar>
      </properties>
    </profile>
    <profile>
      <id>osx_profile</id>
      <activation>
        <activeByDefault>false</activeByDefault>
        <os>
          <family>mac</family>
        </os>
      </activation>
      <properties>
        <toolsjar>${java.home}/../Classes/classes.jar</toolsjar>
      </properties>
    </profile>
  </profiles>

  <dependencies>
    <dependency>
      <groupId>com.sun</groupId>
      <artifactId>tools</artifactId>
      <version>1.6.0</version>
      <scope>system</scope>
      <systemPath>${toolsjar}</systemPath>
    </dependency>
  </dependencies>

I'm not allowed to change the POM file, so I had to do some jiggery pokery. I copied the tools.jar from my Java 6 JDK, created the directory C:\java\lib and pasted it there. I then restarted eclipse and cleaned my project. And VOILA errors are gone.

It's not an elegant solution, and I would think that the proper solution would be to change the way the POM is setup, but as I was not able to, this works.

After trying out all the above I was still having the same issue    PATH environment variable point to JDK 1 7 bin My JAVA HOME environment variable was pointed to the JDK 1 7 My eclipse ini had the javaw -vm entry pointing to JDK 1 7 My eclipse preference had JDK 1 7 as the installed JRE  My project build path was using JDK 1 7    Then I tried the following    Open a command prompt and typed java -version  It showed me a JRE version 1 8  Open a command prompt and went to location of the JDK 1 7 bin directory and typed java -version  This time it showed correctly 1 7    Then after digging at few places I found that apart from the above locations there are additional locations for Java runtime   Registry  There is also a registry key where JRE location are specified under     HKLM Software Javasoft Version   I changed the entries here to point to the JDK 1 7  ProgramData  The directory  C  ProgramData Oracle Java javapath  is present in PATH environment variable and contains shortcuts to the java  javaw etc    The target for these shortcuts were all JRE 1 8   This I think was the main problem  I changed the shortcuts to point to the correct JDK exe s   Once all of this was done  I opened eclipse all the jdk tools pom xml errors disappeared

Add this dependecy in pom xml file  Hope this help  In  lt systemPath gt  property you have to write your jdk lib path         lt dependency gt               lt groupId gt com sun lt  groupId gt               lt artifactId gt tools lt  artifactId gt           lt version gt 1 4 2 lt  version gt           lt scope gt system lt  scope gt           lt systemPath gt C  Program Files Java jdk1 6 0 30 lib tools jar lt  systemPath gt           lt  dependency gt

After struggling for a while I finally got this to work with eclipse ini instead of the command line  After finally reading the documentation I realized that the -vm argument must be on a separate line  unquoted  and ahead of any -vmargs   -vm C  Program Files Java jdk1 7 0 45 bin javaw exe

Problem is system is not able to find the file tools jar  So first check that the file is there in the JDK installation of the directory     Make the below entry in POM xml as rightly pointed by others   lt dependency gt   lt groupId gt com sun lt  groupId gt   lt artifactId gt tools lt  artifactId gt   lt version gt 1 6 lt  version gt   lt scope gt system lt  scope gt   lt systemPath gt C  Program Files Java jdk1 8 0 241 lib tools jar lt  systemPath gt   lt  dependency gt     then Follow the below steps also to remove the problem  1  Right Click on your project   2  Click on Build path   As per the below image  select the workspace default JRE and click on finish

I got similar error  This is because JDK is not properly set in eclipse  Cucumber needs JDK along with JRE  so add below dependency in your pom xml   lt dependency gt     lt groupId gt com sun lt  groupId gt     lt artifactId gt tools lt  artifactId gt     lt version gt 1 6 lt  version gt     lt scope gt system lt  scope gt     lt systemPath gt C  Program Files Java jdk1 8 0 101 lib tools jar lt  systemPath gt   lt  dependency gt

I had the same trouble while developing a simple  web service application  in my case I had to add a codehous plug in in order to get jaxws libraries  However  maven pom kept on asking about the tools jar file    I have to say above comments are correct  you can include the below entry in the pom file     lt dependency gt      lt groupId gt com sun lt  groupId gt      lt artifactId gt tools lt  artifactId gt      lt version gt 1 6 lt  version gt      lt scope gt system lt  scope gt      lt systemPath gt C  Program Files Java jdk1 6 0 29 lib tools jar lt  systemPath gt    lt  dependency gt    But  what will it happen when you have to deploy to a production instance  You could replace the path with a reference to a system environment variable but that still does not look good  at least to me   I found another solution in a StackOverflow comment   Maven 3 Artifact problem   lt dependency gt       lt groupId gt org apache struts lt  groupId gt       lt artifactId gt struts2-core lt  artifactId gt       lt version gt   struts2 version  lt  version gt       lt exclusions gt           lt exclusion gt               lt artifactId gt tools lt  artifactId gt               lt groupId gt com sun lt  groupId gt           lt  exclusion gt       lt  exclusions gt   lt  dependency gt    They suggest including an exclusion statement for tool jar and it works  So summarizing  you can include an exclusion rule within your dependency and avoid having the tool jar issue     lt exclusions gt               lt exclusion gt                   lt artifactId gt tools lt  artifactId gt                   lt groupId gt com sun lt  groupId gt               lt  exclusion gt           lt  exclusions gt

If you are seeing this on newly installed upgraded Operating system  it is just because JAVA HOME is not set properly  we need to set JAVA HOME properly  For example on mac  if I want to use java version 1 8 0 261 export JAVA HOME   usr libexec java home -v 1 8 0 261

In the effective POM tab of the pom files  I see the following derive path  C  Program Files Java jre6    lib tools jar and I think it s not a valid path in Windows  I tried copying the tools jar in the jre6 lib folder as well as in Java lib without success   The value  C  Program Files Java jre6  comes from the registry   HKEY LOCAL MACHINE SOFTWARE JavaSoft Java Runtime Environment 1 6 0 30 HKEY LOCAL MACHINE SOFTWARE JavaSoft Java Runtime Environment 1 6   And set the JavaHome key to where your jdk JRE is installed  Then all the compiler errors went away   Reinstalling the JDK didn t fix it  Setting the JAVA HOME or java home system environment variable didn t help   The other alternative I ve seen is adding the dependency with the right path in each pom xml file  but the playn-samples has lots of files that is a ridiculous pain to have to edit   This is the effective POM results  which show the WRONG path     lt dependency gt         lt groupId gt com sun lt  groupId gt         lt artifactId gt tools lt  artifactId gt         lt version gt 1 6 lt  version gt         lt scope gt system lt  scope gt         lt systemPath gt C  Program Files Java jre6    lib tools jar lt  systemPath gt         lt optional gt true lt  optional gt       lt  dependency gt

I got this problem and it turns out that JBossDevStudio 9 1 on Windows is a 32-bit program  Eclipse  and thus the JBossDevStudio  does not work with the wrong type of JVM  64-bit eclipse needs a 64-bit JVM  32-bit eclipse needs a 32-bit JVM  Thus configuring Eclipse to run with my installed 64-bit JDK did not work   Installing a 32 bit JDK and running Eclipse from that solved the problem   At least for one of my projects  an other where I had tried to configure a runtime JDK in the Eclipse project properties is still broken

I had the same problem on a Windows 7 and Eclipse 3 7 I managed to fix it by starting      eclipse exe -vm  D  JDK6 bin    You can start a cmd and launch eclipse like that  or you can edit your shortcut and add -vm  D  JDK6 bin  as an argument in the  target section    As a sidenote  I also tried to add -vm  D  JDK6 bin  to eclipse ini but did not work  And adding JRE6 will not work since it does NOT contain tools jar in it s  lib  directory  Only JDK does

In my case  I was executing Maven Build from Eclipse Run Configurations  Even after changing the default JRE configuration to point to JDK installation folder  the issue didn t get fixed for me  The reason is that there is a JRE tab in the Maven Build - Run Configuration  see the image below   And it was still pointing to my JRE installation  I changed it to point to JDK installation and then ran the Maven Build  This time  it worked  enter image description here

I just posted over on this question about this same issue and how I resolved it  but I ll paste  and expand on  it here as well  since it seems more relevant   I had the same issue when using Eclipse in Windows 7  even when I removed the JRE from the list of JREs in the Eclipse settings and just had the JDK there   What I ended up having to do  as you mentioned in your question  was modify the command-line for the shortcut I use to launch Eclipse to add the -vm argument to it like so   -vm  T  Program Files Java jdk1 6 0 26 bin    Of course  you would adjust that to point to the bin directory of your JDK install  What this does is cause Eclipse itself to be running using the JDK instead of JRE  and then it s able to find the tools jar properly   I believe this has to do with how Eclipse finds its default JRE when none is specified  I m guessing it tends to prefer JRE over JDK  why  I don t know  and goes for the first compatible JRE it finds  And if it s going off of Windows registry keys like Vladiat0r s answer suggests  it looks for the HKLM Software JavaSoft Java Runtime Environment key first instead of the HKLM Software JavaSoft Java Development Kit key

Changing the relative location of   java home     lib tools jar to the absolute path of C  Program Files Java jdk1 6 0 29 lib tools jar works for me   You should only have to change it in the playn pom xml   Now for the playn-samples  Vladiator is right  that s too many pom files to change

I solved the problem by uninstalling JRE from my system and leaving JDK only   Reinstall JDK is not enough because Oracle JDK installer installs both JDK and JRE  BTW  it seems to me that this bug is responsible for troubles  java home of the Eclipse JRE is used instead of the build JRE

I ran into the same problem and the way I was able to resolve it was add the dependency location of tools jar into the pom xml   Like so     lt dependency gt      lt groupId gt com sun lt  groupId gt      lt artifactId gt tools lt  artifactId gt      lt version gt 1 6 lt  version gt      lt scope gt system lt  scope gt      lt systemPath gt C  Program Files Java jdk1 6 0 29 lib tools jar lt  systemPath gt    lt  dependency gt    Make sure you change the  lt systemPath gt  to where ever your tools jar file is located

If this problem still happens  it might be because of a JDK of version equal or greater than 11   The tools jar archive has been removed from the lib folder in those JDK s  see this answer to a similar question   In that case  try to use other versions of the libraries  that do not rely on the com sun tools library

None of the other answers did it for me  What did it was to check for  Dependency hierarchy  of the pom xml in eclipse  where giving a filter  tools  revealed that I had a real dependency to tools jar     So the culprit for me was this    lt dependency gt       lt groupId gt com github markusbernhardt lt  groupId gt       lt artifactId gt robotframework-selenium2library-java lt  artifactId gt       lt version gt 1 4 0 7 lt  version gt       lt scope gt test lt  scope gt   lt  dependency gt    Adding an exclusion fixed it    lt dependency gt       lt groupId gt com github markusbernhardt lt  groupId gt       lt artifactId gt robotframework-selenium2library-java lt  artifactId gt       lt version gt 1 4 0 7 lt  version gt       lt scope gt test lt  scope gt       lt exclusions gt           lt exclusion gt               lt artifactId gt tools lt  artifactId gt               lt groupId gt com sun lt  groupId gt           lt  exclusion gt       lt  exclusions gt     lt  dependency gt    The exclusion doesn t seem to have any downsides to it

Let s understand why this issue happened        mvn -version           Apache Maven 3 6 1  d66c9c0b3152b2e69ee9bac180bb8fcc8e6af555  2019-04-04T20 00 29 01 00      Maven home  C  Program Files Apache maven-3 6 1     Java version  1 8 0 221  vendor  Oracle Corporation  runtime  C  Program Files Java jre1 8 0 221     Default locale  en GB  platform encoding  Cp1252     OS name   windows 10   version   10 0   arch   amd64   family   windows       Maven  mvn -version  command returns above output    We can see maven gets the java runtime path as  C  Program Files Java jre1 8 0 221  if you don t specify JAVA HOME environment variable  And then maven assumes this path to be JAVA HOME  That s why when building the application either from command prompt or any IDE  maven looks for tools jar file in path   JAVA HOME    lib tools jar    tools jar is present in JDK path  so we need to mention this to maven before using it  Now a days machines are build with already available jre  but jdk is only required for development  This might be the reason why maven picks jre path automatically   For more help  please read the code mvn cmd available in maven installation path
