[MPLUGIN-524] "org.apache.maven.artifact.repository.metadata.Plugin.getPrefix() is null" with Nexus Staging plugin

While attempting to release a plugin with nexus-staging-maven-plugin, I get the following exception:

Downgrading to 3.12.0 works fine. The bug is similar to MPLUGIN-384 and I suspect it was introduced with MPLUGIN-520.

The big question for me is: Is this a flaw in our code or a flaw in the plugin? We consider the plugin as useless these days. Tamas Cservenak ,  sjaranowski .

Tamas Cservenak commented

Just take a peek at stack trace:

• org.sonatype.nexus.maven.staging.deploy.strategy.AbstractDeployStrategy.deployUp initiates a deploy
• goes thru org.eclipse.aether.internal.impl.DefaultDeployer
• and then resolver ends up here, in a Maven2 class https://github.com/apache/maven/blob/master/maven-compat/src/main/java/org/apache/maven/artifact/repository/metadata/MetadataBridge.java
• hence, it means that DeployRequest.metadata contained this Maven2 class, and request was created by offender in first bullet

Slawomir Jaranowski commented

unfortunately it is still widely used
https://github.com/search?q=nexus-staging-maven-plugin+language%3A%22Maven+POM%22&type=code&l=Maven+POM

We should talk with Sonatype about it ... how we cen help to improve ...

Also Sonatype prepare next plugin for new Central portal
https://central.sonatype.org/publish/publish-portal-maven/ 

I afraid it is similar to old one

None of refd issues are related, cause is this MNG-8121.

Meaning, user had no prefix set beforehand, and now that m-p-p requires it, the old MD used by staging plugin pukes.

Tamas Cservenak commented

I am keep saying that "staging" in Maven is not solved, and will never be solved by these third-party sub-optimal plugins. We need to step up and do something about this, like proof of concept MDK is https://github.com/maveniverse/mdk Am really really clueless why no Maven dev reviews and/or responds about it on ML.

[jira-importer]

Tamas Cservenak commented

Possible circumvention: downgrade to "working" one (3.12.0), make your plugin have a (now mandatory) prefix, deploy, upgrade.

[jira-importer]

Tamas Cservenak commented

Real solution: move off this unsupported and pretty much dead plugin. Maven4 is soon coming, while this one is still from Maven2 times.

Just wondering, is nexus-staging-maven-plugin useless? How else are we supposed to release to Sonatype? All our jobs for Eclipse EE4J and Jakarta EE use the nexus-staging-maven-plugin.

[jira-importer]

Tamas Cservenak commented

Eclipse uses Nx2 just like ASF. We do not use this plugin.

[jira-importer]

David Matějček commented

Just fyi, the plugin seems compatible with Maven 3.8.6. We need to fix it for Jakarta EE projects.

Alvaro Sanchez-Mariscal commented

Tamas Cservenak it is false that this is caused by a missing prefix. I've always had a prefix.

On Central there is a prefix (although different?), whilst on s01 there isn't.

Regarding the Nexus Staging plugin, I think we all followed Sonatype's recommendation here. What is your advise for today's Maven 3? Just use maven-deploy-plugin? Because as far as I can tell, it won't do releases with a staging workflow that implies:

• Staging locally.
• Creating a private staging remote repository.
• Performing atomic upload into staging repository.
• Closing staging repo (or dropping if upload failed).

The closest would be m-d-p's deployAtEnd, but if I'm not mistaken, it doesn't perform a "transactional release", and considering that Sonatype won't delete incomplete release artifacts, I see a high risk here,

[jira-importer]

Tamas Cservenak commented

Vanilla deploy plugin will not stage locally, true, but will create (implicitly) staging remote repository, nexus-staging plugin does not deploy "atomically" either, and yes, staging plugin can close the staging repository...

So, as long as Nexus2 is in picture, I'd recommend vanilla maven-deploy-plugin, as nexus-staging plugin has severe issues.
