mvn validate

The Maven Plugin creates the following version.properties file:

version=1.0.1

mvn validate

The Plugin has an optional parameter “includeEmptyDirs” with a default value “false”. Add the parameter to the plugin configuration to copy any empty directories included in the Resources.

...
<includeEmptyDirs>true</includeEmptyDirs>
...

Execute specific Maven goal using profiles

			</build>
		</profile>
	</profiles>
</project>

To call the above profiles, run the following command:

mvn validate -Pprofile-one

or

mvn validate -Pprofile-two

If you call validate without a profile no goal will be executed:

mvn validate

Profiles can also be active by default using a configuration like the following:

<profiles>
  <profile>
    <id>profile-one</id>
    <activation>
      <activeByDefault>true</activeByDefault>
    </activation>
    ...
  </profile>
</profiles>

For more informations have a look at the Build Lifecycle and Profiles.
