Conflict between JBoss-IDE plugin and Rational ClearCase SCM ------------------------------------------------------------ Key: JBIDE-116 URL: http://jira.jboss.com/jira/browse/JBIDE-116 Project: JBoss Tools Issue Type: Bug Reporter: SourceForge User SourceForge Submitter: ericeberry . I have been getting this exception when trying to Run XDoclet with JBoss-IDE 1.4.0 and Eclipse 3.0.1. !ENTRY org.eclipse.core.runtime 4 2 Nov 08, 2004 09:07:29.742 !MESSAGE An internal error occurred during: "XDoclet Generation". !STACK 0 java.lang.IllegalArgumentException: Attempted to beginRule: R/, does not match outer scope rule: P/bnc1.5 at org.eclipse.core.internal.runtime.Assert.isLegal (Assert.java:58) at org.eclipse.core.internal.jobs.ThreadJob.illegalPush (ThreadJob.java:106) at org.eclipse.core.internal.jobs.ThreadJob.push (ThreadJob.java:200) at org.eclipse.core.internal.jobs.ImplicitJobs.begin (ImplicitJobs.java:80) at org.eclipse.core.internal.jobs.JobManager.beginRule (JobManager.java:170) at org.eclipse.core.internal.resources.WorkManager.checkIn (WorkManager.java:95) at org.eclipse.core.internal.resources.Workspace.prepareOp eration(Workspace.java:1628) at org.eclipse.core.internal.resources.Resource.refreshLocal (Resource.java:1224) at org.jboss.ide.eclipse.xdoclet.run.ui.actions.XDocletRunAct ion$1.run(XDocletRunAction.java:191) at org.eclipse.core.internal.jobs.Worker.run (Worker.java:66) It turns out there is a conflict between the JBoss-IDE plugin and the Rational ClearCase SCM Adapter 6.0.24 plugin. Becuase this plugin is "always on", we can't turn the plugin off. We have to disable the plugin to turn it off. I disabled the plugin and I was able to run xdoclet every time. As soon as I re-enabled the plugin. Run XDoclet stopped working.
