SNAPSHOTs: maven-metadata incorrectly calculates snapshotVersion?

[mmoayyed]

Expected and Results

Perhaps a continuation of #73

Using the latest versions of the plugin here, 1.1.x, I see the following maven-metadata.xml file is published for an artifact:

<?xml version="1.0" encoding="UTF-8"?>
<metadata modelVersion="1.1.0">
  <groupId>org.apereo.cas</groupId>
  <artifactId>cas-server-support-bom</artifactId>
  <versioning>
    <lastUpdated>20250911235415</lastUpdated>
    <snapshot>
      <timestamp>20250911.235415</timestamp>
      <buildNumber>230</buildNumber>
    </snapshot>
    <snapshotVersions>
      <snapshotVersion>
        <extension>pom</extension>
        <value>7.3.0-20250911.235415-1</value>
        <updated>20250911235415</updated>
      </snapshotVersion>
      <snapshotVersion>
        <extension>pom.asc</extension>
        <value>7.3.0-20250911.235415-1</value>
        <updated>20250911235415</updated>
      </snapshotVersion>
    </snapshotVersions>
  </versioning>
  <version>7.3.0-SNAPSHOT</version>
</metadata>

Note how the <buildNumber>230</buildNumber> is set, yet all <value> tags point to -1. This effectively makes the artifact invisible to Maven:

The project org.apereo.cas:apereo-cas-build:1.0.0-SNAPSHOT (/Users/misagh/Workspace/GitWorkspace/cas-server/ci/verify-pom.xml) has 5 errors
[ERROR]     Non-resolvable import POM: The following artifacts could not be resolved: org.apereo.cas:cas-server-support-bom:pom:7.3.0-SNAPSHOT (absent): Could not find artifact org.apereo.cas:cas-server-support-bom:pom:7.3.0-20250911.235415-1 in sonatype-snapshots (https://central.sonatype.com/repository/maven-snapshots/) @ line 31, column 25 -> [Help 2]

I suspect the counter here should follow the build number, and not restart at 1. Is there a bug here?

Related environment and versions

• Gradle 9.1 RC3
• Java 21

Reproduction steps

• Attempting to publish SNAPSHOTs via:

./gradlew publishAggregationToCentralPortalSnapshots \
    --info -x test -x javadoc -x check --no-daemon --parallel \
    -DskipAot=true -DpublishSnapshots=true --stacktrace \
    --no-configuration-cache --configure-on-demand \
    -DrepositoryUsername="$REPOSITORY_USER" \
    -DrepositoryPassword="$REPOSITORY_PWD"

I see:

Nmcp: put 'https://central.sonatype.com/repository/maven-snapshots/org/apereo/cas/cas-server-support-bom/7.3.0-SNAPSHOT/maven-metadata.xml'

The produced metadata seems incorrect:
https://central.sonatype.com/repository/maven-snapshots/org/apereo/cas/cas-server-support-bom/7.3.0-SNAPSHOT/maven-metadata.xml

Anything else?

Thanks for sharing this. Fix is at #193. I'll update nmcp to use it and if everything looks good will publish a new version.

[martinbonnin]

This seems to work well here. Any chance you can try the Nmcp snapshot before I cut a release?

[martinbonnin]

1.2.0 is released, let us know how that works!

[mmoayyed]

Thank you 👍 I will return with an update before the end of the week.

Thanks! Let me know how that goes!
