Is it possible to override executions in maven pluginManagement?

Question

In parent POM, I have:

 
            
                maven-resources-plugin

A quick option is to use <phase>none</phase> when overriding each execution. So for example to run execution 3 only you would do the following in your pom:

<build>
  <plugins>
    <plugin>
        <artifactId>maven-resources-plugin</artifactId>
        <version>2.5</version>
        <executions>
            <execution>
                <id>execution 1</id>
                <phase>none</phase>
                ...
            </execution>
            <execution>
                <id>execution 2</id>
                <phase>none</phase>
                ...
            </execution>
            <execution>
                <id>execution 3</id>
                ...
            </execution>
        </executions>
    </plugin>
    ...
  </plugins>
  ...
</build>

It should be noted that this is not an officially documented feature, so support for this could be removed at any time.

The recommend solution would probably be to define profiles which have activation sections defined:

<profile>
  <id>execution3</id>
  <activation>
    <property>
      <name>maven.resources.plugin.execution3</name>
      <value>true</value>
    </property>
  </activation>
  ...

The in your sub project you would just set the required properties:

<properties>
    <maven.resources.plugin.execution3>true</maven.resources.plugin.execution3>
</properties>
