Michael Osipov commented on MNG-6556:
-------------------------------------
Something between Maven Install Plugin 2.4 and 3.0.0-M1 introduced a bug where
the {{maven-metadata.xml}} of for the plugin prefix is not written.
One can use this to poke around with:

~/apache-maven-3.6.0/bin/mvn -Dmaven.repo.local=$(pwd)/../repo-3.6.0 clean
install
~/apache-maven-3.6.1-SNAPSHOT/bin/mvn
-Dmaven.repo.local=$(pwd)/../repo-3.6.1-SNAPSHOT clean install
[mosipov@mika-ion
~/Projekte/maven-integration-testing/core-it-suite/target/test-classes/mng-3372/direct-using-prefix/project]$
~/apache-maven-3.6.0/bin/mvn -Dmaven.repo.local=$(pwd)/../repo-3.6.0 -s
../settings.xml mng3372:test
~/apache-maven-3.6.0/bin/mvn -Dmaven.repo.local=$(pwd)/../repo-3.6.1-SNAPSHOT
-s ../settings.xml mng3372:test
~/apache-maven-3.6.1-SNAPSHOT/bin/mvn
-Dmaven.repo.local=$(pwd)/../repo-3.6.1-SNAPSHOT -s ../settings.xml
mng3372:test
~/apache-maven-3.6.1-SNAPSHOT/bin/mvn -Dmaven.repo.local=$(pwd)/../repo-3.6.0
-s ../settings.xml mng3372:test
{noformat}
Maven fails with the error that the plugin with that prefix cannot be found in
any repo with the given plugin group from the local settings file.
Here is the diff between those two repos:
!diff in mc.png!
Note that the metadata file is missing in the 3.6.1-SNAPSHOT repo.
I haven't yet started going back in history of the plugin, but I assume it is
some dependency which broke it.
[~khmarbaise], any idea?
