[jira] [Commented] (MASSEMBLY-923) NPE when axis:axis-ant:1.4 is
part of dependencySet
[ https://issues.apache.org/jira/browse/MASSEMBLY-923?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16996562#comment-16996562 ]
Karl Heinz Marbaise commented on MASSEMBLY-923:
-----------------------------------------------
It is caused by that the given [artifact contains an relocation|https://search.maven.org/artifact/axis/axis-ant/1.4/jar] and not a real artifact.
If you take a look into the [given pom file|https://repo1.maven.org/maven2/axis/axis-ant/1.4/axis-ant-1.4.pom] which looks like this:
{code:xml}
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>axis</groupId>
<artifactId>axis-ant</artifactId>
<version>1.4</version>
<distributionManagement>
<relocation>
<groupId>org.apache.axis</groupId>
</relocation>
</distributionManagement>
</project>
{code}
If you change the groupId of the dependency the given example works perfect.
So the question is: Can we somehow identify such situation in maven assembly plugin?

> ---------------------------------------------------
>
> Key: MASSEMBLY-923
> URL: https://issues.apache.org/jira/browse/MASSEMBLY-923
> Project: Maven Assembly Plugin
> Issue Type: Bug
> Components: dependencySet
> Affects Versions: 3.1.1, 3.2.0
> Reporter: Václav Haisman
> Priority: Critical
>
> I can reproduce a NPE when axis:axis-ant:1.4 is part of dependencySet. See GitHub repository [https://github.com/wilx/maven-assembly-plugin-npe] for easy reproduction. Just run mvn clean install. It appears to be caused by the POM format of the axis-ant as it is installed in Maven Central. This was tested with Maven 3.6.2.
