How to skip Maven plugin parent pom execution? - maven

Question

I have a parent aggregator POM with multiple modules. I have a build/pluginManagement in the parent since plugin execution is the same for each sub module.
If I execute in each sub module (mvn package) it works fine. If I execute in the parent: mvn package -Pmytest, I want to skip plugin execution in the parent module, so I added:
<plugin>
<groupId>org.wildfly.plugins</groupId>
<artifactId>wildfly-maven-plugin</artifactId>
<configuration>
<skip>true</skip>
</configuration>
</plugin>
However, it's not working.

I'm getting a file not found error. The file is not supposed to exists here. The issue is why it's not skipping parent module execution.

I found the issue. If the execution id is parameterized, in my case:
<plugin>
<groupId>org.wildfly.plugins</groupId>
<artifactId>wildfly-maven-plugin</artifactId>
<executions>
<execution>
<id>add-${project.artifactId}</id>
...
...
<executions>
<execution>
<id>remove-${project.artifactId}</id>
...
...
to skip plugin execution, you'd have to explicitly specify the execution id and phase:
<plugin>
<groupId>org.wildfly.plugins</groupId>
<artifactId>wildfly-maven-plugin</artifactId>
<executions>
<execution>
<id>add-jboss-config</id>
<phase/>
</execution>
<execution>
<id>remove-jboss-config</id>
<phase/>
</execution>
</executions>
<configuration>
<skip>true</skip>
</configuration>
</plugin>
Now, it skips the parent, executes in all the children modules, and I only have one place for plugin configuration.
Note: I tried using static execution ids, but it has the side effect of skipping execution in the children modules as well. Also, I'm not sure if all of these issues are just in wildfly-maven-plugin.
