Checking an artifact with pom packaging fails

[bazusaladra]

The plugin loads just the pom.xml contents instead of the cached checksum, did you lose ".sha1" part?

Please run mvn with -X, extract the relevant 'DEBUG' information from the log, and add to this issue report.

I assume that version 0.6.0 works?

[bazusaladra]

Version 0.6.0 works. Now it fails on the checksum comparison for an artifact:

<failIfExists>false</failIfExists>
<cmpChecksum>true</cmpChecksum>
<failIfNotMatch>true</failIfNotMatch>
