maven compilation failure

Question

I have a weird problem - Some class file couldn t be read during maven build    I have a project A and project B  Project B depends on the project A target JAR file    During the project B compilation it is not able to read lib in the project A JAR file - though the part directed to it is perfect   I have also checked and verified the maven script and it is perfect   Error    INFO  Compiling 137 source files to V  dhs tss build view dhs tssproject tss tsscommon-server target classes  INFO  ------------------------------------------------------------------------  ERROR  BUILD FAILURE  INFO  ------------------------------------------------------------------------  INFO  Compilation failure  V  dhs tss build view dhs tssproject tss tsscommon-server src main java us mn state dhs tss common oblix da wsdl OblixLoginAc cess java  51 60  cannot find symbol symbol    class BusinessException location  class us mn state dhs tss common oblix da wsdl OblixLoginAccess  V  dhs tss build view dhs tssproject tss tsscommon-server src main java us mn state dhs tss common app da ldap BaseLdapImpl j ava  187 14  cannot find symbol symbol    class Phone location  class us mn state dhs tss common app da ldap BaseLdapImpl  V  dhs tss build view dhs tssproject tss tsscommon-server src main java us mn state dhs tss common app da ldap BaseLdapImpl j ava  204 14  cannot find symbol symbol    class Phone location  class us mn state dhs tss common app da ldap BaseLdapImpl    INFO  ------------------------------------------------------------------------  DEBUG  Trace org apache maven BuildFailureException  Compilation failure         at org apache maven lifecycle DefaultLifecycleExecutor executeGoals DefaultLifecycleExecutor java 579          at org apache maven lifecycle DefaultLifecycleExecutor executeGoalWithLifecycle DefaultLifecycleExecutor java 499          at org apache maven lifecycle DefaultLifecycleExecutor executeGoal DefaultLifecycleExecutor java 478          at org apache maven lifecycle DefaultLifecycleExecutor executeGoalAndHandleFailures DefaultLifecycleExecutor java 330           at org apache maven lifecycle DefaultLifecycleExecutor executeTaskSegments DefaultLifecycleExecutor java 291          at org apache maven lifecycle DefaultLifecycleExecutor execute DefaultLifecycleExecutor java 142          at org apache maven DefaultMaven doExecute DefaultMaven java 336          at org apache maven DefaultMaven execute DefaultMaven java 129          at org apache maven cli MavenCli main MavenCli java 287          at sun reflect NativeMethodAccessorImpl invoke0 Native Method          at sun reflect NativeMethodAccessorImpl invoke NativeMethodAccessorImpl java 39          at sun reflect DelegatingMethodAccessorImpl invoke DelegatingMethodAccessorImpl java 25          at java lang reflect Method invoke Method java 585          at org codehaus classworlds Launcher launchEnhanced Launcher java 315          at org codehaus classworlds Launcher launch Launcher java 255          at org codehaus classworlds Launcher mainWithExitCode Launcher java 430          at org codehaus classworlds Launcher main Launcher java 375  Caused by  org apache maven plugin CompilationFailureException  Compilation failure         at org apache maven plugin AbstractCompilerMojo execute AbstractCompilerMojo java 516          at org apache maven plugin CompilerMojo execute CompilerMojo java 114          at org apache maven plugin DefaultPluginManager executeMojo DefaultPluginManager java 451          at org apache maven lifecycle DefaultLifecycleExecutor executeGoals DefaultLifecycleExecutor java 558              16 more  INFO  ------------------------------------------------------------------------  INFO  Total time  1 minute 56 seconds  INFO  Finished at  Mon Oct 19 09 46 53 CDT 2009  INFO  Final Memory  11M 20M  INFO  ------------------------------------------------------------------------

If your dependencies are fine  check with mvn dependency list  like mine were  then it s a maven glitch  if you re using Eclipse do    Right click the project   Maven   Update Project    Check everything but Offline OK   You should be good   I don t know the equivalent mvn commands  if anyone could post them they could be useful

My guess is a wrong version of project A jar in your local maven repository  It seems that the dependency is resolved otherwise I think maven does not start compiling but usually these compiling error means that you have a version mix up  try to make a maven clean install of your project A and see if it changes something for the project B     Also a little more information on your setting could be useful    How is maven launched  what command  on a shell  an IDE  using a plugin or not   on a CI server   What maven command are you using

It also matters the order of the dependencies  I ve had the same issue  And basically I had to put first the scope test and then scope compile dependencies in the pom xml  If I put first the scope compile and then the scope test it will fail

Try to use   mvn clean package install   This command should install your artifacts in you local maven repo   PS  I see that this is an old question  but it may be helpful for somebody in the future

I had the same problem and this is how I suggest you fix it   Run   mvn dependency list   and read carefully if there are any warning messages indicating that for some dependencies there will be no transitive dependencies available   If yes  re-run it with -X flag   mvn dependency list -X   to see detailed info what is maven complaining about  there might be a lot of output for -X flag   In my case there was a problem in dependent maven module pom xml - with managed dependency  Although there was a version for the managed dependency defined in parent pom  Maven was unable to resolve it and was complaining about missing version in the dependent pom xml  So I just configured the missing version and the problem disappeared

It s easy to get this error in a multi-module project   If  for example  you made changes to modules A  B  and C  but then you try to compile just module B  you are susceptible to this error   Say module B has a dependency on module A  Since only module B was compiled  the class files from module A are now out of date and possibly invalid   Compiling all the modules  or modules in the proper hierarchical dependency order  resolves this error  if this is the nature of your problem

The error is pretty clear   cannot find symbol   Some dependencies can t be resolved  you even have the line and column in the trace of the reference that can t be resolved    V  dhs tss build view dhs tssproject tss tsscommon-server src main java us mn state dhs tss common oblix da wsdl OblixLoginAc cess java  51 60  cannot find symbol symbol    class BusinessException location  class us mn state dhs tss common oblix da wsdl OblixLoginAccess  V  dhs tss build view dhs tssproject tss tsscommon-server src main java us mn state dhs tss common app da ldap BaseLdapImpl j ava  187 14  cannot find symbol symbol    class Phone location  class us mn state dhs tss common app da ldap BaseLdapImpl  V  dhs tss build view dhs tssproject tss tsscommon-server src main java us mn state dhs tss common app da ldap BaseLdapImpl j ava  204 14  cannot find symbol symbol    class Phone location  class us mn state dhs tss common app da ldap BaseLdapImpl   Below a couple of things to verify    Check or recheck that these classes are in the jar A  same version as in the pom  Check or recheck the import statement in B sources  should match the package of classes in A  Check or recheck B s pom xml and especially the declaration of the dependency on A  it s version  Check that the dependency on A is not excluded transitively somewhere in B s pom Is A a SNAPSHOT dependency  If no  delete A from your local repository and rebuild   Maven is working fine  you have a mistake somewhere

Just now I also met the problem   ERROR  Failed to execute goal org apache maven plugins maven-compiler-plugin 3 8 1 compile  default-compile  on project entry-api  Compilation failure  Compilation failure   package com foo entry common domain does not exist package com foo entry common model does not exist package com foo entry common service does not exist package com foo entry common util does not exist   Took a long time got the reason  that is one of the dependency jar is spring boot fat jar  so the solution is move below code in its pom xml   lt build gt       lt plugins gt           lt plugin gt               lt groupId gt org springframework boot lt  groupId gt               lt artifactId gt spring-boot-maven-plugin lt  artifactId gt           lt  plugin gt       lt  plugins gt   lt  build gt

I had a similar problem  and never find anything on the web after excessive searching   I reviewed the pom xml file and in the dependencies I changed the scope of the  lt dependency gt  it   lt scope gt test lt  scope gt  to  lt scope gt compile lt  scope gt     Previously I was using it only for tests but I change the project s structure and never knew I hve to change this       test  This scope indicates that the dependency is not required for   normal use of the application  and is only available for the test   compilation and execution phases       compile  This is the default scope  used if none is specified  Compile   dependencies are available in all classpaths of a project    Furthermore  those dependencies are propagated to dependent projects    Here is a reference from Apache Maven Docs  https   maven apache org guides introduction introduction-to-dependency-mechanism html Dependency Scope

It COULD be due to insufficient heap memory   It sounds strange  but try it  it might just work   export MAVEN OPTS  -Xms384M -Xmx512M -XX MaxPermSize 256M    Source  https   groups google com group neo4j msg e208be9ee1c101d7

I had the same issue  even though the project was compiling working fine in Eclipse   it was not when using the command line build  The reason was that I wasn t using the correct folder structure for mvn   src main java com  etc  It is looking at these folders by default  I was using   scr main com  etc  which caused issues

After running following command - mvn clean package install  I found the issue   dependencies dependency scope  for org springframework boot spring-boot-starter-data-rest pom must be one of  provided  compile  runtime  test  system  but is  import     line 13  column 11   One of the dependency was marked as  import   Changing the  scope  solved the issue for me

User · Answer

You could try running the  mvn site  command and see what transitive dependencies you have  and then resolve potential conflicts  by ommitting an implicit dependency somewhere   Just a guess  it s a bit difficult to know what the problem could be without seeing your pom info

User · Answer

go to the maven repository and open the jar  tip  you can use winzip  of the source module to verify the specific class present   In my case it is not  Then I found below   if you are using the plugin org apache felix maven-bundle-plugin  Make sure source module has export-package defined  example  com xxx camel dao
