Maven exec plugin execution conundrum

Sample maven output:

Shouldn't my-validation-one echo "My validation one" to the console? Why does it seem like maven is getting its wires crossed?

Thanks, Steven

You should put the configuration specific to the execution within the execution block. Then it should work correctly.

 <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <executions>
      <execution>
        <id>my-validation-two</id>
        <phase>validate</phase>
        <goals>
          <goal>exec</goal>
        </goals>
        <configuration>
           <executable>echo</executable>
           <arguments>
              <argument>"My validation two"</argument>
           </arguments>
        </configuration>
      </execution>
    </executions>
  </plugin>

Also, if both the executions are bound to same phase and goal, you can combine then within executions block instead of declaring the plugin twice.
