Maven/Ant echoproperties at build time

Once you have started using automation tools for continuous builds, you often find edge cases where your builds have minor variations due to the environments on which the projects have been built. To isolate these, it is often useful to have the build tool output a snapshot of it’s properties at the time the project was built. Thankfully, Ant and Maven make this easy to implement, required additions to your config files are below for each tool.

Maven: (pom.xml)

....
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.7</version>
<executions>
<execution>
<phase>install</phase>
<configuration>
<target>
<echoproperties />
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>

NOTE: ‘target’ is preferred over ‘tasks’ in newer versions of the plugin, it was deprecated in 1.5.

Ant: (build.xml)

...
<echoproperties />
