Github user bbende commented on the issue: https://github.com/apache/nifi/pull/1156 @olegz I pushed up a second commit that with the change that I described above, and also some of the changes from your feedback. Unfortunately I had already rebased my branch before you had started reviewing, so i ended up having to force push, but I left it as two commits where the first one has the stuff you already looked at, and the second commit has changes after that. I think the remaining discussion point is mostly around how restrictive we get regarding what happens when one or more resources can't be found. I understand the point about what happens if something that is necessary can't be loaded, but I also want to give flexibility to the developers using this feature. There may be cases where someone wants to provide a couple of directories that are common locations for a given library, and if found then load whatever is found, but if not then maybe they don't care. One option might be to provide a validator that uses ClassLoader.getURLsforClasspath to validate everything resolves, and then document that this is available, but not enforce that it is always used.
