How do I run a specific goal with a particular configuration in a Maven plugin when I have several configurations for that goal

Question

See plugin config from pom.xml below.

I can do:

mvn myplugin:myGoal

Which runs myGoal (both executions I suppose) but I want to be able to choose either the first or the second executions independently.

I know I can add an id to the execution element, but how do I refer to that id on the command line. I'd like to get to something which does what this imagined command does:

mvn myplugin:myGoal --executionId=1

Is this possible, or am I going about this the wrong way?

        <plugin>             <groupId>org.myplugin</groupId>             <artifactId>myplugin-maven-plugin</artifactId>             <version>1.1.1</version>             <executions>                 <execution>                     <id>process-cats</id>                     <goals>                         <goal>myGoal</goal>                     </goals>                     <configuration>                         <myParam>cats</myParam>                     </configuration>                 </execution>                 <execution>                     <id>process-dogs</id>                     <goals>                         <goal>myGoal</goal>                     </goals>                     <configuration>                         <myParam>dogs</myParam>                     </configuration>                 </execution>             </executions>         </plugin> 

Answer 1

Execution of multiple goals from the CLI is now supported in Maven 3.3.1+

mvn exec:java@first-cli mvn exec:java@second-cli 

Where first-cli/second-cli are the execution ids.

For your example the commands would be

mvn myplugin:mygoal@process-cats mvn myplugin:mygoal@process-dogs 

Answer 2

I can do mvn myplugin:myGoalWhich runs myGoal (both executions I suppose)

None of them (assuming they had unique id). Executions are bound to a phase, you need to run the given phase to trigger them.

I know I can add an id to the execution element, but how do I refer to that id on the command line.

Not supported. What is possible for plugins invoked on the CLI is to define a non global configuration in the POM using the special default-cli executionId, like this:

<plugin>   <artifactId>maven-assembly-plugin</artifactId>   <executions>     <execution>       <id>default-cli</id>       <configuration>         <descriptorRefs>           <descriptorRef>jar-with-dependencies</descriptorRef>           <descriptorRef>project</descriptorRef>         </descriptorRefs>       </configuration>     </execution>   </executions> </plugin> 

Is this possible, or am I going about this the wrong way?

No, not possible. Either pass the parameters on the command line or use profiles (with or without the above default execution).
