If I surround a General build step (as described in the snippet generator) in a try-catch block, within a scripted Jenkins file, the error is not caught.
for example I expected the following code block to mark the build as unstable. But an error is thrown at the archiveArtifacts step.
EDIT (abayer): More generally - CoreStep executions of a SimpleBuildStep (such as archiveArtifacts, which is actually calling the ArtifactArchiver publisher from core), only throw an exception if the SimpleBuildStep itself throws an exception. And as a general rule, failure-but-not-error cases (like the non-existent path case here) of a SimpleBuildStep don't throw an exception, since the FreeStyleBuild they were initially used in would proceed anyway (especially in the case of publishers/recorders, which are the most common SimpleBuildStep implementations), after having set the build status.
