Sonatype Maven Shell and Parallel builds in Maven 3

Today I played around with the parallel build feature from Maven 3 and with the sonatype maven shell. The sonatype maven shell is based (required) on Maven 3. Here my first build performance results.

	Maven 3	Maven 3 (mvn -T 10)	Maven 3 (mvn -T 1.5C)	Maven Shell
mvn clean compile	ca. 5 sec	ca. 3 sec	ca. 4 sec	ca. 2 sec
mvn clean package	ca. 12 sec	ca. 10 sec	ca. 10 sec	ca. 7 sec
mvn package	ca. 7 sec	ca. 6 sec	ca. 6 sec	ca. 3 sec
mvn clean site	ca. 4 min	ca. 4 min	ca. 4 min	crashed
mvn javadoc:javadoc	ca. 56 sec	ca. 29 sec	ca. 29 sec	ca. 27 sec

Apache Maven 3 and the Maven Site Plugin

Today I have a look on maven 3 features, when I start to build the maven site of my project it always failed. Because the configuration for the maven site was changed in the maven version 3.X. Here my first maven site configuration that worked for my project:

	<build>
