             Summary: Regression in 3.1.2 when installing pom artifact
                 Key: MINSTALL-201
                 URL: https://issues.apache.org/jira/browse/MINSTALL-201
             Project: Maven Install Plugin
          Issue Type: Bug
    Affects Versions: 3.1.2
         Environment: macOS 14.5, Maven 3.9.8; probably any
            Reporter: Christian Kohlschütter


With 3.1.2, I'm seeing wrong artifact metadata (POM files) being installed for 
POM-packaged artifacts in a multi-module project.

Prior to 3.1.2, we were excluding some operations in InstallMojo.java when a 
project's packaging was "pom". The check got removed, leading to ".pom" 
artifact files being installed as some sort of zip file (yet having the ".pom" 
file suffix).

This breaks all sorts of things for me, effectively rendering version 3.1.2 
unusable.

Patch forthcoming.

To reproduce:
{code:java}
git clone [email protected]:kohlschutter/kohlschutter-parent.git
git checkout kohlschutter-parent-1.7.2
cd kohlschutter-parent
mvn clean install -Dignorant -DskipTests
file 
$HOME/.m2/repository/com/kohlschutter/kohlschutter-parent-multirelease/1.7.2/kohlschutter-parent-multirelease-1.7.2.pom
# the above command should return something like "XML 1.0 document text, ASCII 
text"
# 
# now change maven-install-plugin dependency version in kohlschutter-parent's 
pom.xml from 3.1.1 to 3.1.2
mvn clean install -Dignorant -DskipTests
file 
$HOME/.m2/repository/com/kohlschutter/kohlschutter-parent-multirelease/1.7.2/kohlschutter-parent-multirelease-1.7.2.pom
# 
# the above command now returns something like "Zip archive data, at least v1.0 
to extract, compression method=store"
# 
# contents of the zip file:
# META-INF/
# META-INF/MANIFEST.MF
# META-INF/maven/
# META-INF/maven/com.kohlschutter/
# META-INF/maven/com.kohlschutter/kohlschutter-parent-multirelease/
# META-INF/maven/com.kohlschutter/kohlschutter-parent-multirelease/pom.xml
# 
META-INF/maven/com.kohlschutter/kohlschutter-parent-multirelease/pom.properties}}
