What phase do I use for my task? - maven

Question

I'm using Maven 3.0.3. I want to run a task to copy environment specific properties before I package my WAR file. Below is my task.
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<phase>prepare-package</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<tasks>
<delete file="${project.build.outputDirectory}/environment.properties"/>
<copy file="src/main/resources/${env}_environment.properties"
tofile="${project.build.outputDirectory}/environment.properties" />
<delete file="${project.build.outputDirectory}/${env}_hibernate.cfg.xml"/>
<copy file="src/main/resources/${env}_hibernate.cfg.xml"
tofile="${project.build.outputDirectory}/hibernate.cfg.xml" />
<echo message="Copied ${env}_hibernate.cfg.xml properties. " />
</tasks>
</configuration>
</execution>
</executions>
</plugin>
However, when start up my app, invoking a goal from my Tomcat profile, by running "mvn -P tomcat tomcat:run", the above task doesn't get run. Any ideas how I can correct this? The Tomcat profile I include is below. - Dave

Answer 1

You should attach it to the compile phase. This will actually get executed after the compilation has finished.

Answer 2

The maven-antrun-plugin runs at prepare-package so you can add that to your command:
mvn -P tomcat tomcat:run prepare-package

Answer 3

From documentation of tomcat:run,
tomcat:run Invokes the execution of the lifecycle phase compile prior to executing itself.
prepare-package phase comes later - before package
Perhaps you should try tomcat:run-war.
tomcat:run-war Invokes the execution of the lifecycle phase package prior to executing itself.
