How do I link a plugin execution to a phase in maven without forcing me to specify plugin on command line

Question

I have a simple pom and added an ant-run to the compile but it only executes then when I do the following: mvn install antrun:run
mvn install -- doesn't process the ant-run mvn antrun:run -- doesn't process the ant-run

I thought that be linking the plugin to the lifecyce phase that the plugin would be executed when I try to achieve that phase. This is not what is happening.

Am I missing some nuance, do I need to have a profile which enables the plugin?

Thanks for the help (pom below)

Answer 1

You've specified the plugin below the <pluginManagement> section. This means that this configuration will be used if the plugin is also declared directly under build/plugins, for example in a child POM.

To make it work in this instance remove the <pluginManagement> tags so that <plugins> is directly below <build> like this:

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      ...
    </plugin>
  </plugins>
</build>

Answer 2

You need to add a phase.

e.g.:

      <executions>
            <execution>
                <id>xml2fastinfoset</id>
                <phase>generate-sources</phase>
                <goals>
                    <goal>xml2fastinfoset</goal>
                </goals>
            </execution>
        </executions>
