A Maven Projection That Bring Multiple Holding Files Via Maven Antrun Plugin

This tutorial volition response several questions (below) within a maven projection that has several configuration files (dataset, property, persistence).

1.) How to accept multiple persistence, datasource too belongings files depending on the profile or surroundings variable (xxx-dev, xxx-integr, xxx-prod)?

2.) How to execute a maven copy/rename/move inwards a pom?

3.) How to execute an emmet if within a maven pom?

It's best to response this inquiry inwards this uncomplicated chunk of code :-)

<plugin>  <artifactId>maven-antrun-plugin</artifactId>  <version>1.7</version>  <executions>   <execution>    <phase>install</phase>    <configuration>     <target>      <echo>Execute emmet tasks</echo>      <taskdef resource="net/sf/antcontrib/antcontrib.properties">      </taskdef>      <if>       <isset property="local.tomcat.home" />       <then>        <copy         file="${project.basedir}/src/main/resources/ipiel-${env}.properties"         tofile="${local.tomcat.home}\conf\ipiel.properties" />       </then>      </if>      <copy       file="${project.basedir}/src/main/resources/META-INF/persistence-${env}.xml"       tofile="${project.build.directory}/${project.artifactId}-${project.version}/META-INF/persistence.xml" />     </target>     </configuration>    <goals>     <goal>run</goal>    </goals>   </execution>  </executions>  <dependencies>   <dependency>    <groupId>ant-contrib</groupId>    <artifactId>ant-contrib</artifactId>    <version>20020829</version>   </dependency>  </dependencies> </plugin> 

Some notes:
1.) We demand to define a dependency to ant-contrib to endure able to role the emmet if tag.
2.) The re-create belongings file volition execute if property local.tomcat.home is set.

Note, using -P production volition solely activate that profile simply volition non supervene upon whatsoever variable inwards the actual belongings file. To endure able to larn the actual file nosotros demand to specify -Denv=prod. Also nosotros demand to bind it to the exam stage too non the install phase.
