I'm not 100% sure if this will fix the issue.
There are 2 issues which both result in an ArrayIndexOutOfBoundsException.
One has to do with a process instruction inside the plugin configuration
(fixed).
You mean the m2e configuration thing like "<?m2e ...>"...
This is fixed ,cause this will fail in all Maven versions if you use a
parent which contains such configuration...Tested with the current
master of plexus-utils it works fine...
But if we have a new release of plexus-utils we could at least tell
people in such cases to replace the plexus-utils to prevent this issue...
The other has to do with invalid XML.
Ok this is a different story...
It looks to me that most of the time the second issue is being hit.
Clearing the local repository and re-downloading the pom file is the
cure. (this is actually the best way to identify which of the 2 is being
hit)
What I've seen is that sometime the content of the pom is duplicated, i.e.
<project>
...
</project>
<project>
...
</project>
I could imagine that this happens when a 2 threads download the same pom
at the same time and for some reason are appended.
From the same Maven run ? Or by using two different maven runs which
use the same local cache ?
Up until Maven 3.3.9 the XML stopped at the closing root-tag, not at the
document-end.
Maybe I misunderstand a thing but isn't the reading of the XML file done
by plexus-utils?
When the pom is not a valid XML, then IMHO the pom should be re-downloaded.
There are now a couple of issues:
- you cannot see which pom is causing the ArrayIndexOutOfBoundsException
- you cannot simply switch to strict checksums at system level. You
cannot use MAVEN_OPTS in this case because --strict-checksum is a Maven
argument, not a JVM argument.
Couldn't checkSum policy being used in settings.xml to configured to fail ?
Kind regards

These issues need to be fixed in Maven.
So I would go for improving this in Maven, just updating plexus-utils
will give users false hope.
Maybe we don't need to make the release of plexus-utils very prominent ;-)
Kind regards

thanks,

Hi,
based on the current issue related to reading pom files etc.
(ArrayIndexOutOfBoundsException)
I would like to make a new release of Plexus-Utils 3.1.0.....after
that people can simple replace the old version of plexus-utils-3.0.24
in their maven installation with the new one until we made a new
release of Maven Core ....
If there are no objections I would like to start with the release at
Tuesday ?
Kind regards
Karl Heinz Marbaise
