Description

Error installing artifact's metadata: Error installing metadata: Error updating group repository metadata

end tag not allowed in epilog but got / (position: END_TAG seen ...\n

Looks like there might be an issue with updates to maven-metadata-local.xml during the mvn install task. we have a build server that is multi threaded. we often see this in the

</versioning>
</metadata>
</metadata>

maven-metadata-local.xml.

maybe a solution is to add maven-metadata-local.xml.lock to ensure two threads don't update the file at the same time

note that there is a duplicate report here http://jira.codehaus.org/browse/MINSTALL-54 but as the fix is inside this project i've raised a second bug report here.

The recommended practice for the Invoker is to use a private local repository somewhere inside the project's output directory where concurrency concerns should not apply. Hence, I am tempted to close this as won't fix.

I understand the point about the recommended practice, but...

The proposed fix - adding maven-metadata-local.xml.lock - seems pretty simple. Why not go ahead and fix it and save people like me the trouble of researching the problem and figuring out a workaround?

I think there are probably a lot of Maven users like me that just want to use the tool without making a career out of understanding all the ins and outs. That's possible because great tools like Maven "will run with sensible defaults" (see http://maven.apache.org/run-maven/index.html#Quick_Start for quote). In this case Maven doesn't run (at least not reliably) with the default behavior, and I'm using up a good chunk of my Sunday trying to figure out a workaround that won't break something else.

I agree with Benjamin.
Also, when comparing the overhead/costs of IO, synchronized methods (which only works within the same JVM), sleeps and timeouts with the chance that this situation occurs, IMHO it's not worth it.
