Can t start Eclipse - Java was started but returned exit code 13

Question

I am trying to get my first taste of Android development using Eclipse  I ran into this problem when trying to run Eclipse  having installed version 4 2 only minutes ago   After first trying to start Eclipse without any parameters to specify the Java VM  I got an error message saying it couldn t find a Java VM called javaw exe inside the Eclipse folder  so I found where Java was installed and specified that location as the parameter in the shortcut s target  Now I get a different error  Java was started but returned exit code 13   Similar questions seem to indicate that it s a 32-bit 64-bit conflict  but I m 99  positive that I downloaded 64-bit versions of both Eclipse and Java  RE 7u5   which I chose because I have 64-bit Windows 7     If anyone knows how to confirm that my Eclipse and Java are 64-bit  that d be appreciated  If you think my problem is a different one  please help  Please speak as plainly as you can  as I am totally new to Eclipse and Java       Shortcut Target   C  Program Files Eclipse-SDK-4 2-win32-x86 64 eclipse eclipse exe  -vm  C  Program Files  x86  Java jre7 bin javaw exe    Full error code      Java was started but returned exit code 13 C  Program Files  x86  Java jre7 bin javaw exe -Xms40m -Xmx512m -XX MaxPermSize 256m -jar C  Program Files Eclipse-SDK-4 2-win32-x86 64 eclipse  plugins org eclipse equinox launcher 1 30v20120522-1813 jar -os win32 -ws win32 -arch x86 64 -showsplash C  Program Files Eclipse-SDK-4 2-win32-x86 64 eclipse  plugins org eclipse platform 4 2 0 v201206081400 splash bmp -launcher C  Program Files Eclipse-SDK-4 2-win32-x86 64 eclipse eclipse exe -name Eclipse --launcher library C  Program Files Eclipse-SDK-4 2-win32-x86 64 eclipse  plugins org eclipse equinox launcher win32 win32 x86 64 1 1 200 v201205221813 eclipse 1503 dll -startup C  Program Files Eclipse-SDK-4 2-win32-x86 64 eclipse  plugins org eclipse equinox launcher 1 30v20120522-1813 jar --launcher overrideVmargs -exitdata 1e30 5c -vm C  Program Files  x86  Java jre7 bin javaw exe -vmargs -Xms40m -Xmx512m -XX MaxPermSize 256m -jar C  Program Files Eclipse-SDK-4 2-win32-x86 64 eclipse  plugins org eclipse equinox launcher 1 30v20120522-1813 jar

The top answer didn t work for me  I had no environment variables defining the Java path or no Java in my path   However  the path C  ProgramData Oracle Java javapath javaw exe was always present in the Eclipse 4 5  Mars  error popup in the -vm option even if I tried to override in file eclipse ini   I worked around this by opening a command prompt  cd ing the directory where the eclipse exe was and using MKLink   C  EclipseMars gt  mklink javaw exe  C  Program Files Java jdk1 7 0 79 bin  symbolic link created for javaw exe  lt  lt     gt  gt  C  Program Files Java jdk1 7 0 79 bin   No changes to eclipse ini were required   I did try to specify the -vm option of in eclipse ini  and it was taken into account  but in the error popup a -vm option was present twice even if only one -vm was present in eclipse ini   In my eclipse ini I have no -vm option and just the symlink seems to have corrected it

I have just solved the same issue upon setting up my Windows 8 1 PC  Exactly like  George Papatheodorou mentioned above  sorry I cannot add a comment   Eclipse and JRE must be both 64 bit or 32 bit   However  it seems for Windows 8 8 1 environment  you are going to get 32-bit JRE by default  and I do not know where to change that default for the download   as explained here  http   java com en download faq win8 faq xml  I was using 64-bit Eclipse so there was a discrepancy  I then installed 32-bit Eclipse and everything works fine this time   So before bothering changing any environment variables  check your JRE and Eclipse version   Of course you can use 64-bit JRE with 64-bit Eclipse  Just make sure they match because Windows 8 1 will give you 32-bit by default

User · Answer

This type of errors occur basically due to use of different versions of Java with different version of Eclipse   Suppose you are installing the 64-bit JDK on your system  Then make sure you install the 64-bit versioned Eclipse with it   And if you are installing the 32-bit JDK on your system then make sure you install 32-bit versioned Eclipse with it   I had the similar problem  I have installed the 32-bit JDK and was trying to use 64-bit Eclipse   But when I installed the 64-bit JDK on my system then Eclipse started working without any problem   It is advised to better install the 32-bit version of Java along with the 32-bit version Eclipse on a system with a 32-bit configuration and similarly for 64-bit systems   This helps to increase performance of the system

I also encountered the same issue  It turned out that the environment variable Path was pointing to an incorrect Java version   Please check the environment variable and point it to the correct Java  For example    C  Program Files  x86  Java jdk1 6 0 17 bin   To check the environment variable  go to   Computer   properties   Advanced system settings   Advanced - gt  Environment variables

User · Answer

Please check whether you have set two JAVA paths in the Environment Variable section  If you already installed two versions of the JDK  it might be  then double check you have put PATH for Java like below   PATH -- gt   C  ProgramData Oracle Java javapath   and also  JAVA HOME --- gt  C  Program Files Java jdk1 7 0 02 bin   If both are there  then this sort of error may occur   If it s OK  then check in the   ini  file the below area is OK or not  Open   ini  file and check   -VM  path is  C  Program Files Java jdk1 7 0 79 bin    If not  please set it like that and run again

At the risk of not adding a great deal of value to the existing answers  but having gone through all this mess myself  I would like to see if I can consolidate how I addressed the problem    Maintain separate Development from your normal machine environments   The reason for this is that there are probably many applications running on your machine that you are not aware of that need Java to be updated occasionally  for example banking and security applications   When those updates occur they change the environmental variables and so if you are using those in your development environment the update will almost certainly break your Eclipse setup   Install versions of Eclipse  either 32 and 64 bit depending on your plugins etc   The reason is that many plugins still require 32bit and trying to install them into a 64bit environment causes many obscure  very obscure  errors   This means for example you may have to have separate instances of Eclipse for your  Java EE  PHP  Python  Assembler  etc   development environments   This may appear to be onerous   but for me this has been a blessing  Install two Java runtimes once again one 32bit and one 64bit and then edit the eclipse ini for each of your installations to point to the correct JRE  not the JRE HOME in the environmental variables   I create a directory in C  Java 64bit jdk1 7 0 15  and C  Java 32bit etc and in your eclipse ini file you add the -vm C  Java 64bit jdk1 7 0 15 bin line to point to your needed java runtime    Once the above is done you can install Java SDKs updates as much as you like but your development environment will never break   If you need to update your development runtime environment just alter the -vm path in your eclipse ini

If you install a 64-bit Eclipse version on a PC with a 32-bit JRE this is guaranteed to occur   So the solution is quite straightforward  You need to synchronise them by updating either one  This shall happen when downloading Oracle Fusion middleware and Eclipse expects a 32-bit environment while your JRE is 64-bit and your JAVA home is pointing to a 64-bit JDK

I got this error and found that my PATH variable  on Windows  was probably changed  First in my PATH was this entry   C  ProgramData Oracle Java javapath      and Eclipse ran  C  ProgramData Oracle Java javapath javaw  - which gave the error  I suspect that this is something that came along with an installation of Java 8   I have several Java versions installed  6 7 and 8   so I removed that entry from the PATH and tried to restart Eclipse again  which worked fine   If it s doesn t work for you  you ll need to upgrade your JDK  to the Java versions - 8 in this case     Instructions on how to edit PATH variable

User · Answer

Your version of Eclipse is 64-bit  based on the paths and filenames  However  the version of Java that it s picking up is 32-bit  as indicated by where it is coming from  on this line   -vm C  Program Files  x86  Java jre7 bin javaw exe   Program Files  x86  is the folder where 64-bit Windows places 32-bit programs   Program Files is the folder where 64-bit Windows places 64-bit programs   This can happen when a system has more than one JVM installed  as is often the case on Windows 64-bit  for example  the JRE download page uses the bit-ness of the browser to determine what bit-ness download to offer you  and many people use d  32-bit browsers even though they run 64-bit Windows    The best way to fix this  assuming you do in fact have 64-bit JRE or JDK on your system  is to specify in eclipse ini exactly which JVM you want it to use  The instructions are detailed in the Eclipse wiki page  but basically you have to specify the -vm option in the ini file - make sure to read the wiki page carefully as the format is very specific   Specifying the JVM path in eclipse ini is strongly recommended because doing so isolates Eclipse from any potential changes to your system PATH that some program installers might make  I m talking to you  Oracle     Another option would be to download and use 32-bit Eclipse instead of 64-bit  but it s still strongly recommended to specify the path to the JVM in eclipse ini     Left for historical reference   To check your version of Java  run      java -version    in a console  command prompt   On Windows 7 with 64-bit Java 6 I get      java version  1 6 0 27    Java TM  SE Runtime Environment  build 1 6 0 27-b07    Java HotSpot TM  64-Bit Server VM  build 20 2-b06  mixed mode    Note the 3rd line  which shows that this is a 64-bit version    On a 32-bit version you ll get something like      Java HotSpot TM  Client VM  build 20 1-b02  mixed mode  sharing     If you are on a 64-bit machine  then you can install the 64-bit JDK and uninstall the 32-bit one  For instance on Windows 10  just go to Settings and under Apps  you will find Java  Click on it and you will find all the different versions  Now you can select which one to uninstall
