Hello, I have some problem with Continuum 1.0.3 after upgrading from 1.0.2. I have followed exactly the procedure described here : http://maven.apache.org/continuum/upgrade.html I'm using external application folders. After migrating, everything seems to be OK : - all projects are presents - I am able to read last build log But : - build history is empty for each projects, even if build log files appear in history folder - if I launch a build (M2 project), it fails with the following error : **************************************************************************** Build Error: **************************************************************************** org.apache.maven.continuum.execution.ContinuumBuildExecutorException: Error while mapping metadata. at org.apache.maven.continuum.execution.maven.m2.MavenTwoBuildExecutor.updateProjectFromCheckOut(MavenTwoBuildExecutor.java:117) at org.apache.maven.continuum.core.action.UpdateProjectFromWorkingDirectoryContinuumAction.execute(UpdateProjectFromWorkingDirectoryContinuumAction.java:64) at org.apache.maven.continuum.buildcontroller.DefaultBuildController.build(DefaultBuildController.java:273) at org.apache.maven.continuum.buildcontroller.BuildProjectTaskExecutor.executeTask(BuildProjectTaskExecutor.java:47) at org.codehaus.plexus.taskqueue.execution.ThreadedTaskQueueExecutor$ExecutorRunnable.run(ThreadedTaskQueueExecutor.java:103) at java.lang.Thread.run(Thread.java:595) Caused by: org.apache.maven.continuum.execution.maven.m2.MavenBuilderHelperException: Cannot build maven project from /home/m2/continuum-folders/working-directory/44/pom.xml (null). at org.apache.maven.continuum.execution.maven.m2.DefaultMavenBuilderHelper.getMavenProject(DefaultMavenBuilderHelper.java:339) at org.apache.maven.continuum.execution.maven.m2.DefaultMavenBuilderHelper.mapMetadataToProject(DefaultMavenBuilderHelper.java:112) at org.apache.maven.continuum.execution.maven.m2.MavenTwoBuildExecutor.updateProjectFromCheckOut(MavenTwoBuildExecutor.java:113) ... 5 more Caused by: java.lang.NullPointerException at org.codehaus.plexus.util.xml.pull.MXSerializer.writeElementContent(MXSerializer.java:912) at org.codehaus.plexus.util.xml.pull.MXSerializer.text(MXSerializer.java:776) at org.apache.maven.settings.io.xpp3.SettingsXpp3Writer.writeSettings(SettingsXpp3Writer.java:581) at org.apache.maven.settings.io.xpp3.SettingsXpp3Writer.write(SettingsXpp3Writer.java:71) at org.apache.maven.continuum.execution.maven.m2.DefaultMavenBuilderHelper.writeSettings(DefaultMavenBuilderHelper.java:489) at org.apache.maven.continuum.execution.maven.m2.DefaultMavenBuilderHelper.getMavenProject(DefaultMavenBuilderHelper.java:301) ... 7 more What to do to upgrade succesfully ?
