Since the last 0.13 snapshot update Mylyn tests started to fail. http://ci.mylyn.org/job/mylyn-tasks-trigger/20/console [ERROR] Failed to execute goal org.eclipse.tycho:tycho-surefire-plugin:0.13.0-SNAPSHOT:test (default-test) on project org.eclipse.mylyn.tasks.tests: Error while executing platform: NullPointerException -> [Help 1] org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.eclipse.tycho:tycho-surefire-plugin:0.13.0-SNAPSHOT:test (default-test) on project org.eclipse.mylyn.tasks.tests: Error while executing platform 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.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:319) 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.MojoExecutionException: Error while executing platform at org.eclipse.tycho.surefire.TestMojo.runTest(TestMojo.java:560) at org.eclipse.tycho.surefire.TestMojo.execute(TestMojo.java:361) at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:101) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:209) ... 19 more Caused by: java.lang.NullPointerException at org.eclipse.tycho.equinox.launching.internal.EquinoxLaunchConfiguration.toStringArray(EquinoxLaunchConfiguration.java:94) at org.eclipse.tycho.equinox.launching.internal.EquinoxLaunchConfiguration.getVMArguments(EquinoxLaunchConfiguration.java:113) at org.eclipse.tycho.equinox.launching.internal.DefaultEquinoxLauncher.execute(DefaultEquinoxLauncher.java:49) at org.eclipse.tycho.surefire.TestMojo.runTest(TestMojo.java:558)
Turns out this was not related to a Tycho update but caused by a change to the Hudson job configuration. Nested quotes seems to throw off Tycho: '-Dtest.vmargs="-ea -Dorg.eclipse.mylyn.wikitext.tests.disableOutput=true"' I changed that to "-Dtest.vmargs=-ea -Dorg.eclipse.mylyn.wikitext.tests.disableOutput=true" to fix it (the tests.vmargs property is passed to the surefire plug-in). I'll leave this bug open since it would be helpful if the error handling was improved.

I revisited this issue while fixing bug 427556. You can reproduce it by adding a surefire configuration e.g. in tycho-demo/itp01 <plugin> <groupId>org.eclipse.tycho</groupId> <artifactId>tycho-surefire-plugin</artifactId> <version>${tycho-version}</version> <configuration> <argLine>${test.vmargs}</argLine> </configuration> </plugin> and starting the build using mvn clean verify '-Dtest.vmargs="-ea -Dorg.eclipse.mylyn.wikitext.tests.disableOutput=true"' -X -e you will see in the debug build log: [DEBUG] (f) argLine = "-ea -Dorg.eclipse.mylyn.wikitext.tests.disableOutput=true Note the unbalanced quotes (probably eaten up by the shell process/java process that started mvn) The unbalanced quotes are the root cause, however the root cause is hidden by plexus utils which catch any Exception while parsing the line https://github.com/sonatype/plexus-utils/blob/master/src/main/java/org/codehaus/plexus/util/cli/Commandline.java#L784 You can also see in the build log "Error translating Commandline." This unspecific message masks the more specific exception throw new CommandLineException( "unbalanced quotes in " + toProcess ); being caught. See https://github.com/sonatype/plexus-utils/blob/master/src/main/java/org/codehaus/plexus/util/cli/CommandLineUtils.java#L377 This leaves String[] parts as null causing the follow up NPE.
