Folks,

I am trying to investigate an issue with MINSTALL 3.0.0-M1 for MNG-6556
where the GroupRepositoryMetadata file is simply not written to disk,
thus the IT for MNG-3372 is failing.

As far as I can see everything in Maven 2 for this task has been moved
to Maven Artifact Transfer, Maven31ArtifactInstaller.

I do see in
for ( ArtifactMetadata metadata : mavenArtifact.getMetadataList() )
everything I need is there, but the instanceof tests simply ignore this
kind of metadata and it is never persisted to disk.

I am a bit lost because it looks like a several issue in our codebase.
Is the IT flawed and should exclude the Maven version which will include
MNG-6556 or am I just too stupid to see the obvious?

Here is a simple reproducer:
* Clone MINSTALL
I suppose you maven-install-plugin git repo? ..

* Open pom.xml and add MINSTALL 3.0.0-M1 to override from parent

* Delete org/apache/maven/plugins from your local repo

* Use Maven 3.6.1 to install MINSTALL 3.0.0-M2-SNAPSHOT

maven-metadata-local.xml will *not* be generated, remove change in
pom.xml and repeat, metadata file is there.

Would be nice if someone can confirm this.


Hm...I've tried your steps:

plugins (master)$ ls -la maven-install-plugin/
3.0.0-M1/                 3.0.0-M2-SNAPSHOT/
maven-metadata-local.xml
plugins (master)$ ls -la maven-install-plugin/3.0.0-M2-SNAPSHOT/
total 96

    </snapshotVersions>
  </versioning>

plugins (master)$

and I get a written maven-metadata-local.xml file?

Do I miss something?

In artifact-transfer the generation of the checksum has been moved from
install to deploy...?

Kind regards
