Running a Post-Build Script via maven-invoker-plugin

Question

I am trying to run a simple beanshell script to print 'Hello World' after building the war file. I am making references from this. However, I keep getting "No projects were selected for execution." after running mvn clean install. I am unsure if the error comes from the directories of the files or I am unable to just print 'Hello World' after the war file is built.

   +- project folder/
      +- buildTargetWarFileFolder/
      +- python/
         +- folder/
         |  +-helloWolrd.bsh

           <plugin>
             <artifactId>maven-invoker-plugin</artifactId>
                <version>3.2.1</version>
                <configuration>
                    <debug>true</debug>
                    <projectsDirectory>project folder</projectsDirectory>
                    <postBuildHookScript>python/folder/helloWorld.bsh</postBuildHookScript>
                </configuration>
                <executions>
                    <execution>
                        <id>print Hello World</id>
                        <goals>
                            <goal>run</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

I would recommend using the exec:exec goal directly, binding to the integration-test phase of the maven build (to try out your python script).

      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>exec-maven-plugin</artifactId>
        <version>3.0.0</version>
        <configuration>
          <executable>python</executable>
          <arguments>
            <argument>-c</argument>
            <argument>print('Hello world')</argument>
          </arguments>
        </configuration>
        <executions>
          <execution>
            <id>integration-test</id>
            <phase>integration-test</phase>
            <goals>
              <goal>exec</goal>
            </goals>
          </execution>
        </executions>
      </plugin>

This is the same as running the following on the command line after your war is created:

python -c "print('Hello world')"
