How to set a property based on environment value? - maven

Question

I try to create a maven script which takes care of my packaging for different environments dev, test and production.
I'd like to make some kind of template which copies certain files into a specific directory. Something like this:
<profile>
<id>default-profile</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.8</version>
<executions>
<execution>
<id>prepare-package</id>
<phase>prepare-package</phase>
<configuration>
<target>
<echo message="Copying configuraiton files .."/>
<copy file="${package-mode.config-directory}/x.xml" todir="src/main/webapp/WEB-INF/config" />
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</pluginManagement>
</build>
</profile>
My current problem is that I need ${package-mode.config-directory} to be set according to the environment which I want to build for.
I am currently using the maven-enforcer-plugin in order to require an environment variable to be set:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-enforcer-plugin</artifactId>
<version>1.4.1</version>
<executions>
<execution>
<id>enforce-property</id>
<goals>
<goal>enforce</goal>
</goals>
<configuration>
<rules>
<requireProperty>
<property>package-mode</property>
<message>You must set a "package-mode" property!</message>
<regex>(test|dev|deploy)</regex>
<regexMessage>
[ ########### ] "package-mode"" must be either "test", "dev" or "deploy".
</regexMessage>
</requireProperty>
</rules>
<fail>true</fail>
</configuration>
</execution>
</executions>
</plugin>
But I'm now facing the problem that I need some kind of conditional build for ${package-mode.config-directory}. I would need something like this:
<plugin>
<!-- ... -->
<property>package-mode</property>
<condition>
<equals>test</equals>
<package-mode.config-directory>src/main/assembly/test</package-mode.config-directory>
</condition>
<condition>
<equals>dev</equals>
<package-mode.config-directory>src/main/assembly/dev</package-mode.config-directory>
</condition>
<condition>
<equals>deploy</equals>
<package-mode.config-directory>src/main/assembly/deploy</package-mode.config-directory>
</condition>
</plugin>
Is it possible to do that?

Turns out I could simply use the already enforced environment variable package-mode and just name the directories to its valid values. One can argue about whether this is "nice" or not but it works and it builds my war file:
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<version>3.0.0</version>
<executions>
<execution>
<id>prepare-package</id>
<phase>prepare-package</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>src/main/webapp/WEB-INF/config</outputDirectory>
<resources>
<resource>
<directory>src/main/assembly/${package-mode}/config</directory>
<filtering>true</filtering>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
