Maven exec plugin not running - eclipse

Question

I am trying to executing a powershell script that writes to a file during a maven build.
I am invoking the build with mvn clean install through Eclipse IDE.
This is the plugin in my pom.xml:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.6.0</version>
<executions>
<execution>
<goals>
<goal>exec</goal>
</goals>
</execution>
</executions>
<configuration>
<executable>${project.basedir}/.my-file.ps1</executable>
</configuration>
</plugin>
</plugins>
The powershell script is a hidden file so that's why I have a . in front of the file name.
However, the plugin is not executing and I am following the instructions in the official documentation.

Answer 1

You are running mvn clean install which will go through various build phases, but your exec plugin execution is not attached to any phase. You'll have to either:
Attach your execution to a phase by adding the <phase> element to your execution, for example to attach it to the pre-integration-test phase:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.6.0</version>
<executions>
<execution>
<id>my-exec</id>
<phase>pre-integration-test</phase>
<goals>
<goal>exec</goal>
</goals>
</execution>
</executions>
<configuration>
<executable>${project.basedir}/.my-file.ps1</executable>
</configuration>
</plugin>
Or call specifically the exec goal using mvn exec:exec command.
If you are not familiar with the Maven lifecycle and various phases of a build, read the Introduction to the Build Lifecycle guide, or specifically the Plugins part to learn more about plugins executions and phases attachment.
