The task-scanner plugin and CPD plugin fail to produce reports when I have the
following other post-build actions enabled, even though they are both correctly
configured:

• Publish Javadoc
• Publish JUnit test result report
• Record Emma coverage report
• Publish FindBugs analysis results
• Publish PMD analysis results
• Publish Java NCSS Report
• Editable Email Notification (Email-ext)

All of these others work as expected. The task-scanner and CPD plugins don't
seem to be invoked at all, since the console log ends with something like the
following:

BUILD FAILED

I have tried disabling the Email-ext notification, but this doesn't make any
difference.
