Description

NetBeans users has just recently complained that Maven support is slower than Ant - some even claimed they rather maintain dual Ant script support than wait for Maven to launch. I've created this issue to investigate the problem.

First of all we need a sample project: justtest.diff - apply it patch -p1 <justtest.diff in an empty directory shall be enough. Then you can run it with Maven:

$ time JAVA_HOME=~/bin/jdk-8/ mvn -quiet -Dtest=com.mycompany.justtest.MainTest process-test-classes surefire:test
-------------------------------------------------------
 T E S T S
-------------------------------------------------------
Running com.mycompany.justtest.MainTest
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.071 sec
Results :Tests run: 1, Failures: 0, Errors: 0, Skipped: 0

real    0m2,633s
user    0m6,986s
sys     0m0,257s

and you can also run it with Ant:

 time JAVA_HOME=~/bin/jdk-8/ ant -q test-single -Djavac.includes=com/mycompany/justtest/MainTest.java -Dtest.includes=com/mycompany/justtest/MainTest.java

BUILD SUCCESSFUL
Total time: 1 second

user    0m4,250s
sys     0m0,244s
 

2.6s vs. 1.9s! Really? Is that the problem? Probably not, I guess the difference is the integration into the IDE then.
