Dear list, I am trying to upgrade an existing and working continuum 1.2.3 install towards 1.3.6. To do this, I have followed the upgrade procedure (http://continuum.apache.org/docs/1.3.6/installation/upgrade.html) to the letter. When starting the new continuum, all projects are there, but I cannot build anything. All projects fail with this error:
org.codehaus.plexus.taskqueue.execution.TaskExecutionException: Error executing action 'execute-builder' at org.apache.maven.continuum.buildcontroller.DefaultBuildController.performAction(DefaultBuildController.java:415) at org.apache.maven.continuum.buildcontroller.DefaultBuildController.build(DefaultBuildController.java:157) at org.apache.maven.continuum.buildcontroller.BuildProjectTaskExecutor.executeTask(BuildProjectTaskExecutor.java:48) at org.apache.continuum.taskqueueexecutor.ParallelBuildsThreadedTaskQueueExecutor$ExecutorRunnable$1.run(ParallelBuildsThreadedTaskQueueExecutor.java:12 0) at edu.emory.mathcs.backport.java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:442) at edu.emory.mathcs.backport.java.util.concurrent.FutureTask.run(FutureTask.java:176) at edu.emory.mathcs.backport.java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:987) at edu.emory.mathcs.backport.java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:528) at java.lang.Thread.run(Thread.java:595) Caused by: org.apache.maven.continuum.ContinuumException: No such executor: 'maven2'. at org.apache.maven.continuum.execution.manager.DefaultBuildExecutorManager.getBuildExecutor(DefaultBuildExecutorManager.java:84) at org.apache.maven.continuum.core.action.ExecuteBuilderContinuumAction.execute(ExecuteBuilderContinuumAction.java:96) at org.apache.maven.continuum.buildcontroller.DefaultBuildController.performAction(DefaultBuildController.java:393) ... 8 more This probably means the executors map in DefaultBuildExecutorManager is empty. When starting continuum, it even warns me there are no executors available: 2011-02-02 11:33:59,652 [WrapperSimpleAppMain] WARN org.apache.maven.continuum.execution.manager.DefaultBuildExecutorManager - No build executors defined. I thought this had something to with the migration, but the same warning appears when doing a fresh (= empty data folders) install. This warning appears in 1.3.6 and I even tried 1.3.5, same thing. In 1.4.0 I don't get this warning. There is even a Unit test in your continuum-core, throwing the same exception as the one mentioned above (PrepareBuildProjectsTaskExecutorTest), which I find very disturbing. Can someone please help me getting Continuum 1.3.6 alive? regards, Kenneth
