Double copy of XML in POMs
I got a lot of these error messages using Maven 3.5 on Windows 10.
*The POM for… jar… is invalid, transitive dependencies (if any) will not
be available, enable debug logging for more details*
It turns out that the POM files consisted of a *double copy *of the XML!
See the attached example.
I removed ~/.m2/ and rebuilt, and the POMs were OK.
Is this a known issue? It is very strange to see XML appearing twice.

Hard to tell if we cannot reproduce this. It also could be a Modello
issue. Have you checked open ones with MNG in JIRA?

I'll ask my team to report to me if anyone sees it.

If you ever have some ideas about how this could happen, we're really
curious about those details to be able to reproduce it.
thanks,
Robert

Thank you! Good to know that is is being handled. (It is not a blocker
since we deleted the repository and forced a new download.)

Re: Double copy of XML in POMs

Yes, this is a known issue, see MNG-6281[1] Up until Maven 3.3.9 this was
never an issue, until we fixed MNG-6020[2]. Before that Maven stopped
reading after the closing root-tag.
It is very hard to reproduce. One of the possibilities I have in mind is
that the same pom is required twice (either by 2 Maven executions or as
part of the reactor) and that the files are appended.
I still think MNG-6020 is a good fix: the file must contain valid XML. So
I'd love to see an explanation for this weird behavior and fix it.
thanks,
Robert
