We have recently upgraded mvn compile on HornetQ, a Message-oriented-middleware from RedHat,
and we are now facing a NullPointerException on mac computers, when we upgrade mvn-compiler to 2.5. It all works fine with 2.3.1, and it's funny that only fails on my mac. * https://gist.github.com/3717257 If there's anyone available to take a look, you can download my repo at: git://github.com/clebertsuconic/hornetq.git cd hornetq git checkout mvn-upgrade-fails or you can view it here: https://github.com/clebertsuconic/hornetq/tree/mvn-upgrade-fails * Here is the NPE I"m getting (with mvn -X) [INFO] Compiling 50 source files to /work/hornetq/hornetq/hornetq-commons/target/classes [INFO] ------------------------------------------------------------- [ERROR] COMPILATION ERROR : [INFO] ------------------------------------------------------------- [ERROR] error: java.lang.NullPointerException [INFO] 1 error [INFO] ------------------------------------------------------------- [INFO] ------------------------------------------------------------------------ [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [INFO] Total time: 2.935s [INFO] Finished at: Thu Sep 13 15:13:53 CDT 2012 [INFO] Final Memory: 9M/81M [INFO] ------------------------------------------------------------------------ [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.5.1:compile (default-compile) on project hornetq-commons: Compilation failure [ERROR] error: java.lang.NullPointerException [ERROR] -> [Help 1] org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.5.1:compile (default-compile) on project hornetq-commons: Compilation failure error: java.lang.NullPointerException at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:213) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:153) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:145) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:84) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:59) at org.apache.maven.lifecycle.internal.LifecycleStarter.singleThreadedBuild(LifecycleStarter.java:183) at org.apache.maven.lifecycle.internal.LifecycleStarter.execute(LifecycleStarter.java:161) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:320) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:156) at org.apache.maven.cli.MavenCli.execute(MavenCli.java:537) at org.apache.maven.cli.MavenCli.doMain(MavenCli.java:196) at org.apache.maven.cli.MavenCli.main(MavenCli.java:141) 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:597) at org.codehaus.plexus.classworlds.launcher.Launcher.launchEnhanced(Launcher.java:290) at org.codehaus.plexus.classworlds.launcher.Launcher.launch(Launcher.java:230) at org.codehaus.plexus.classworlds.launcher.Launcher.mainWithExitCode(Launcher.java:409) at org.codehaus.plexus.classworlds.launcher.Launcher.main(Launcher.java:352) Caused by: org.apache.maven.plugin.CompilationFailureException: Compilation failure error: java.lang.NullPointerException at org.apache.maven.plugin.AbstractCompilerMojo.execute(AbstractCompilerMojo.java:729) at org.apache.maven.plugin.CompilerMojo.execute(CompilerMojo.java:128) at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:101) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:209) ... 19 more [ERROR] [ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles: [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoFailureException
