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

问题

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>
                    <goals>
                        <goal>myGoal</goal>
                    </goals>
                    <configuration>
                        <myParam>cats</myParam>
                    </configuration>
                </execution>
                <execution>
                    <goals>
                        <goal>myGoal</goal>
                    </goals>
                    <configuration>
                        <myParam>dogs</myParam>
                    </configuration>
                </execution>
            </executions>
        </plugin>

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).

回答2:

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.

Hey you can create your goal like this:-

org.myplugin:myplugin-maven-plugin:1.1.1:myGoal  i.e
<groupId>:<artifactId>:<version>:<yourgoal>

It works in my case ...

回答4:

The assumption you made that if you call

  mvn myplugin:myGoal

But the problem is that you will get an error message cause the execution have no unique id's (both in this case have the same).

You can reach what you like to do via profiles which you can activate via mvn -PXYZ and mvn -PABC
