- I have found that the task mvn clean, is taking 2 minutes to clean the TARGET folder before building. I did create a new task called quickclean, and i am using it instead of clean, this way
mvn -T 1C quickclean install -Dmaven.test.skip -DskipTests. This new task quickclean is only renaming the build folder from TARGET to TARGET-yyyy-MM-dd-HH-mm(what is VERY FAST). So now, every time you make a newmvn quickclean install..., you have a folder with the time of the build. The inconvient, it’s that this may take a lot of space on the hard disk, so you have to clean all this directories sometimes. So for that i have created another task called: trashclean, to put all this folder to trash. I am running this tasks maybe on time per week. or month, depending on my workmvn trashclean.

Maven 3.x has the capability to perform parallel builds. The command is as follows:
1）mvn -T 4 clean install
Builds with 4 threads
2）mvn -T 1C clean install
1 thread per cpu core
3）mvn -T 1.5C clean install
1.5 thread per cpu core
