I am seeing some random failure in our multi-module gwt app.
Failed to execute goal org.codehaus.mojo:gwt-maven-plugin:2.6.1:compile (compile) on project xxx: GWT Module yyy not found in project sources or resources. -> [Help 1] 2015-08-18 09:26:34 gobuilds.Compile : org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.codehaus.mojo:gwt-maven-plugin:2.6.1:compile (compile) on project xxx: GWT Module yyy not found in project sources or resources. 2015-08-18 09:26:34 gobuilds.Compile : at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:216) 2015-08-18 09:26:34 gobuilds.Compile : at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:153) 2015-08-18 09:26:34 gobuilds.Compile : at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:145) 2015-08-18 09:26:34 gobuilds.Compile : at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:116) 2015-08-18 09:26:34 gobuilds.Compile : at org.apache.maven.lifecycle.internal.builder.multithreaded.MultiThreadedBuilder$1.call(MultiThreadedBuilder.java:189) 2015-08-18 09:26:34 gobuilds.Compile : at org.apache.maven.lifecycle.internal.builder.multithreaded.MultiThreadedBuilder$1.call(MultiThreadedBuilder.java:185) 2015-08-18 09:26:34 gobuilds.Compile : at java.util.concurrent.FutureTask.run(FutureTask.java:262) 2015-08-18 09:26:34 gobuilds.Compile : at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) 2015-08-18 09:26:34 gobuilds.Compile : at java.util.concurrent.FutureTask.run(FutureTask.java:262) 2015-08-18 09:26:34 gobuilds.Compile : at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) 2015-08-18 09:26:34 gobuilds.Compile : at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) 2015-08-18 09:26:34 gobuilds.Compile : at java.lang.Thread.run(Thread.java:745)
We are using:
GWT - 2.6.1 GWT Maven Plugin - 2.6.1
GWT maven args:
-XX:MaxPermSize=512m -Xmx1024m -Djava.io.tmpdir=${project.build.directory} -XX:ReservedCodeCacheSize=256m -XX:+UseCodeCacheFlushing
We are using maven parallel build option with:
-T 2
Interesting thing is 'xxx' is constant and 'yyy' may be different in each run. However, the failure is totally sporadic.
The problem is very hard to reproduce and hence wanted to ask if anyone had some ideas around this?
