---------------------------------------
Summary: Metadata for submodules seems to be incomplete
Key: MINSTALL-191
URL: https://issues.apache.org/jira/browse/MINSTALL-191
Project: Maven Install Plugin
Issue Type: Bug
Components: install:install
Affects Versions: 3.1.1, 3.1.0, 3.0.0, 3.0.0-M1
Environment: Apache Maven 3.8.8
(4c87b05d9aedce574290d1acc98575ed5eb6cd39)
Java version: 11.0.18, vendor: Eclipse Adoptium
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "5.15.0-83-generic", arch: "amd64", family: "unix"
Reporter: Dorian Vallant
Attachments: maven-install-plugin-bug.tgz
maven-install-plugin 3.x (and maven-deploy-plugin 3.x too) seems to have a bug
when generating maven-metadata-*.xml for submodules containing custom
maven-plugins.
With version 2.5.2 maven-install-plugin generates the local metadata as follows:
{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<metadata>
<groupId>at.dvallant.maven</groupId>
<artifactId>plugins</artifactId>
<versioning>
<versions>
<version>0.1.0-SNAPSHOT</version>
</versions>
<lastUpdated>20230831082036</lastUpdated>
</versioning>
<plugins>
<plugin>
<name>my-maven-plugin</name>
<prefix>my</prefix>
<artifactId>my-maven-plugin</artifactId>
</plugin>
</plugins>
</metadata>
{code}
After upgrading to 3.1.1 (also testet with 3.0.0-M1, 3.0.0 and 3.1.0) the
generated file looks this:
{code:xml}
<metadata>
<groupId>at.dvallant.maven</groupId>
<artifactId>plugins</artifactId>
<versioning>
<versions>
<version>0.1.0-SNAPSHOT</version>
</versions>
<lastUpdated>20230831082207</lastUpdated>
</versioning>
</metadata>
{code}
A test-project to reproduce the issue is attached.
To reproduce build the project by calling `mvn clean install` and then check
the contents of
`~/.m2/repository/at/dvallant/maven/plugins/maven-metadata-local.xml`.
If you downgrade the version to 2.5.2, metadata generation works as expected.
If you could give me a hint where the problem might be in the code I can try to
fix it and open a pull request.
