1. Adjust memory configurations to optimum for eg: add this line to mvn.bat set MAVEN_OPTS=-Xmx512m -XX:MaxPermSize=256m

2. Clean phase of mvn normally deletes target folder. Instead if we are renaming target folder the cleaning phase will be much faster.

3. -Dmaven.test.skip=true will skip the test execution.

4. Add -Denforcer.skip=true to mvn command line argument (This is enforcing versions of maven, jdk etc ,we can skip it after initial runs)

5. Disable non-critical operations during build phase: Analysis, javadoc generation, source packaging. This will save huge time.

6. Spawnig new process also helps in time improvement -Dmaven.junit.fork=true (fork the junit tests into a new process) -Dmaven.compile.fork=true (forks the compilation)

   Hope it helps.
