Multi-projects seem to send interrupt signals to some tasks -----------------------------------------------------------
Key: MNG-4358 URL: http://jira.codehaus.org/browse/MNG-4358 Project: Maven 2 Issue Type: Bug Components: Plugins and Lifecycle Affects Versions: 2.2.1 Environment: All 64 bit. Ubuntu 9.10 b5, OpenJDK Runtime Environment (IcedTea6 1.6) (6b16-1.6-1ubuntu1). Reporter: Gustavo Hexsel Tasks like exec:exec and surefire (testing) seem to receive an occasional interrupt signal, causing the test or task to fail. This only happens on multi-module projects (i.e. if I run it a module at a time, it works). Here's an example stacktrace from exec:exec (I can try to reproduce the surefire one as well): [INFO] ------------------------------------------------------------------------ [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] Command execution failed. Embedded error: Error while executing external command, process killed. [INFO] ------------------------------------------------------------------------ [DEBUG] Trace org.apache.maven.lifecycle.LifecycleExecutionException: Command execution failed. at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoals(DefaultLifecycleExecutor.java:584) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoalWithLifecycle(DefaultLifecycleExecutor.java:500) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoal(DefaultLifecycleExecutor.java:479) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoalAndHandleFailures(DefaultLifecycleExecutor.java:331) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeTaskSegments(DefaultLifecycleExecutor.java:292) 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:301) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) 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.MojoExecutionException: Command execution failed. at org.codehaus.mojo.exec.ExecMojo.execute(ExecMojo.java:288) at org.apache.maven.plugin.DefaultPluginManager.executeMojo(DefaultPluginManager.java:453) at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoals(DefaultLifecycleExecutor.java:559) ... 16 more Caused by: org.codehaus.plexus.util.cli.CommandLineException: Error while executing external command, process killed. at org.codehaus.plexus.util.cli.CommandLineUtils.executeCommandLine(CommandLineUtils.java:199) at org.codehaus.plexus.util.cli.CommandLineUtils.executeCommandLine(CommandLineUtils.java:93) at org.codehaus.mojo.exec.ExecMojo.executeCommandLine(ExecMojo.java:437) at org.codehaus.mojo.exec.ExecMojo.execute(ExecMojo.java:279) ... 18 more Caused by: java.lang.InterruptedException at java.lang.Object.wait(Native Method) at java.lang.Object.wait(Object.java:502) at java.lang.UNIXProcess.waitFor(UNIXProcess.java:181) at org.codehaus.plexus.util.cli.CommandLineUtils.executeCommandLine(CommandLineUtils.java:147) ... 21 more -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.codehaus.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
