      My job stopped to poll changes from SVN some time ago - it all runs properly when started manually or by timer, but it won't poll when a change occurs in repository. I have tried tweaking with Maven installations, cloning the job etc. Other jobs using Git do not have this problem. SVN polling shows:

      ERROR: Failed to record SCM polling for hudson.maven.MavenModuleSet@eafaabe[scmTest]

      When I get into job configuration in Maven build section I get "ERROR" below Root POM line. I am attaching the exact ERROR message as a separate file.
