Maven mojo plugin, how to define phases that must be triggered before this goal?

问题

hey, I have a deploy pojo plugin (deploying a war to a remote server). I have the remote-deploy plugin in the build section of pom definition, I need package phase to be triggered before deploy-remote goal, for it the war be already created before I secure-copy it to a remote server.

With the execution elements (according to a documentation), I can attach my goal to a particular phase, for instance bind it to the phase after, so in my case, install phase ...but that's just a workaround.

  <build>
    <plugins>
      <plugin>
        <groupId>sample.plugin</groupId>
        <artifactId>maven-hello-plugin</artifactId>
        <version>1.0-SNAPSHOT</version>
        <executions>
          <execution>
            <phase>package</phase>
            <goals>
              <goal>sayhi</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

simply put, if I place only my goal into the build section, and run it, package phase is not run before. Please help

You can't.

I have the remote-deploy plugin in the build section of pom definition, I need package phase to be triggered before deploy-remote goal, for it the war be already created before I secure-copy it to a remote server.

Just bind it to the package phase, your goal will be called after the goals bounds to package by default (so the war will be there).

Here is an example demonstrating this behavior with the Maven AntRun plugin configured like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.6</version>
    <executions>
      <execution>
        <phase>package</phase>
        <configuration>
          <target>
            <echo message="Hi!!!!!"/>
          </target>
        </configuration>
        <goals>
          <goal>run</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

And the output of mvn package:

$ mvn package

The antrun plugin is executed after package, as expected.

You can try use PREPARE_PACKAGE phase in your @Mojo annotation:

@Mojo(name = "myName", defaultPhase = LifecyclePhase.PREPARE_PACKAGE)
