Maven 从父 pom 中的命令行调用插件

Question

My project sturcture:

 - something-parent -- something-one -- something-two

something-parent -> pom.xml :

 <packaging>pom</packaging> <modules> <module>something-one</module> <module>something-two</module> </modules> <build> <plugins> <plugin> <groupId>io.github.something</groupId> <artifactId>something-maven-plugin</artifactId> <version>1.0.0</version> </plugin> </plugins> </build>

Now I want to execute mvn something:help , but I can't: No plugin found for prefix 'something' .

If I remove modules section - it works. It also works in other modules.

It just doesn't work in parent module with modules section. I couldn't find any documentation or literally anything describing this, is this intended? Is there any workaround?

I know io.github.something:something-maven-plugin:1.0.0:help will work, but I need the shortcut version to work.

//Edit1 - I know about settings.xml solution, but it requires manual edit by user, I would like something on a project level

//Edit2 - found out another quirk, it works when I do mvn something:help -N

I understand that you want to use a short name to refer the plugin when calling it from the command line. To do that, you have to define a plugin group in your settings.xml, as of https://maven.apache.org/settings.html#plugin-groups In your case it would be:

<pluginGroups>
   <pluginGroup>io.github.something</pluginGroup>
</pluginGroups>

This allows you to call:

mvn something:goal
