Debugging Tips and Tricks

The following static fields can be set to true (e.g. via Script Console) while Jenkins is running to enable various debugging aids:

org.kohsuke.stapler.jelly.JellyFacet.TRACE: Jelly will emit XML comments that help understand Jelly view composition from fragments. This can help understand how a view is composed. The corresponding Java system property is stapler.jelly.trace.

Support for Jelly tracing is broken in Jenkins 2.287 and earlier (JENKINS-65288). Some plugins with custom JavaScript may also have problems if this is set to true.

org.kohsuke.stapler.jelly.ReallyStaticTagLibrary.EMIT_LOCATION: Jelly will emit line and file attributes on rendered HTML/XML tags. This can help understand how a view is composed. There is no corresponding Java system property.
