Emmanuel Lécharny commented on MSOURCES-143:
--------------------------------------------
Ok, same issue with Apache MINA. We had a build that worked for more than a
decade, and since I bumped up the dependency to 3.3.0 version, it fails with
the exact same error:
{code:java}
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-source-plugin:3.3.0:jar (attach-source) on
project mina-legal: Presumably you have configured maven-source-plugn to
execute twice times in your build. You have to configure a classifier for at
least on of them. -> [Help 1] {code}
The plugin configuration, which is global for all the modules:
{code:java}
<plugin>
<artifactId>maven-source-plugin</artifactId>
<executions>
<execution>
<id>attach-source</id>
<goals>
<goal>jar</goal>
</goals>
</execution>
</executions>
</plugin>
{code}
The global pom reference: [https://github.com/apache/mina/blob/2.2.X/pom.xml]
This is just happening while I'm tryingh to cut a release with:
{code:java}
mvn -Pserial,apache-release -DdryRun=true release:prepare {code}
Of course, the 'standard' build just works fine:
{code:java}
mvn -Pserial clean install
{code}
