Build Identifier: I20100608-0911 If I call "site.p2" or even "buckminster.clean" on my site feature project I get the following exception. org.eclipse.core.runtime.CoreException: BUILD FAILED at org.eclipse.buckminster.ant.AntRunner.handleInvocationTargetException(AntRunner.java:167) at org.eclipse.buckminster.ant.AntRunner.run(AntRunner.java:322) at org.eclipse.buckminster.ant.actor.AntActor.internalPerform(AntActor.java:254) at org.eclipse.buckminster.core.actor.AbstractActor.perform(AbstractActor.java:186) at org.eclipse.buckminster.core.internal.actor.PerformManager$DirectActionInvocation.execute(PerformManager.java:143) at org.eclipse.buckminster.core.internal.actor.PerformManager.internalPerform(PerformManager.java:454) at org.eclipse.buckminster.core.internal.actor.PerformManager.perform(PerformManager.java:293) at org.eclipse.buckminster.pde.internal.actor.FragmentsActor.internalPerform(FragmentsActor.java:190) at org.eclipse.buckminster.core.actor.AbstractActor.perform(AbstractActor.java:186) at org.eclipse.buckminster.core.internal.actor.PerformManager$DirectActionInvocation.execute(PerformManager.java:143) at org.eclipse.buckminster.core.internal.actor.PerformManager.internalPerform(PerformManager.java:454) at org.eclipse.buckminster.core.internal.actor.PerformManager.perform(PerformManager.java:293) at org.eclipse.buckminster.core.internal.actor.PerformManager.perform(PerformManager.java:305) at org.eclipse.buckminster.ui.InvokeAction$ActionJob.runInWorkspace(InvokeAction.java:81) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:38) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54) Caused by: java.lang.NullPointerException at java.util.Hashtable.put(Unknown Source) at org.apache.tools.ant.PropertyHelper.setUserProperty(PropertyHelper.java:377) at org.apache.tools.ant.Project.setUserProperty(Project.java:543) at org.eclipse.ant.internal.core.ant.InternalAntRunner.setProperties(InternalAntRunner.java:233) at org.eclipse.ant.internal.core.ant.InternalAntRunner.run(InternalAntRunner.java:593) at org.eclipse.ant.internal.core.ant.InternalAntRunner.run(InternalAntRunner.java:495) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.buckminster.ant.AntRunner.run(AntRunner.java:318) ... 14 more Reproducible: Always
This sounds like a duplicate of bug 320586. Can you please try with the latest Buckminster from http://download.eclipse.org/tools/buckminster/headless-3.6 (or updates-3.6 if using the IDE) and see if the problem persists?
Hi Thomas, I already use the latest version. Maybe there is anything I can look for in the properties file?
Apparently ant uses Hashtable's rather then HashMap's. A Hashtable cannot accept a null value. This means that the fix in bug 320586 is no good since it will pass a null property to Ant. Your problem must somehow stem from a property with a null value.
Hi Thomas. The property which is null is: user_homedir. Any idea how to set this? Greetings Axel
No, never seen that. The property that's normally used for the users home directory is the Java System property ${user.home}.
added to my property file: user_homedir=${user.home} and it works. Do not know why this is required now though :-)
