I've been trying out the parallel stuff in maven 3.0.3 and when it works it's great. However I'm wondering what's going on here with this intermittent error. I've never gotten this error bulding single threaded.
https://cwiki.apache.org/MAVEN/parallel-builds-in-maven-3.html says the maven-remote-resources-plugin 1.2 is threadsafe. However... [ERROR] Failed to execute goal org.apache.maven.plugins:maven-remote-resources-plugin:1.2:process (default) on project assemblies: Error rendering velocity resource. NullPointerException -> [Help 1] org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-remote-resources-plugin:1.2:process (default) on project assemblies: Error rendering velocity resource. at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:217) 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.LifecycleThreadedBuilder$1.call(LifecycleThreadedBuilder.java:167) at org.apache.maven.lifecycle.internal.LifecycleThreadedBuilder$1.call(LifecycleThreadedBuilder.java:164) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:680) Caused by: org.apache.maven.plugin.MojoExecutionException: Error rendering velocity resource. at org.apache.maven.plugin.resources.remote.ProcessRemoteResourcesMojo.processResourceBundles(ProcessRemoteResourcesMojo.java:1212) at org.apache.maven.plugin.resources.remote.ProcessRemoteResourcesMojo.execute(ProcessRemoteResourcesMojo.java:519) at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:101) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:209) ... 13 more Caused by: java.lang.NullPointerException at org.apache.velocity.runtime.RuntimeInstance.getTemplate(RuntimeInstance.java:831) at org.apache.velocity.app.VelocityEngine.mergeTemplate(VelocityEngine.java:440) at org.apache.velocity.app.VelocityEngine.mergeTemplate(VelocityEngine.java:419) at org.apache.maven.plugin.resources.remote.ProcessRemoteResourcesMojo.processResourceBundles(ProcessRemoteResourcesMojo.java:1125) ... 16 more I ran with -T 4. It looks like there were 3 failures with this same stack trace all in pom projects that aggregate subprojects. I don't have a lot of time to track down whats going on but might be able to spend a little time given enough advice. thanks david jencks --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@maven.apache.org For additional commands, e-mail: dev-h...@maven.apache.org
