Running a task post maven install

maven, maven-2

Solution

If you want to run this command as part of the normal build lifecycle, there is no other way than binding the `exec` goal on the `install` phase:

<build>
  <plugins>
    <plugin>
      <groupId>org.codehaus.mojo</groupId>
      <artifactId>exec-maven-plugin</artifactId>
      <version>1.1.1</version>
      <executions>
        <execution>
          <id>my-exec</id>
          <phase>install</phase>
          <goals>
            <goal>exec</goal>
          </goals>
          <inherited>false</inherited>
        </execution>
      </executions>
      <configuration>
        <executable>COMMAND</executable>
      </configuration>
    </plugin>
  </plugins>
</build>

I did a simple test using the configuration above (using `ls` as "COMMAND") with a freshly created maven project and running `mvn install` produces the following output:

$ mvn install
[INFO] Scanning for projects...

[INFO] ------------------------------------------------------------------------

As we can see, the command is executed at the end of the `install` phase (after the copy of the artifact to the local repository).

And if you really don't want to add the snippet to your pom, then you'll have to explicitly call `exec:exec` after `install` on the command line as suggested by whaley.
