-----------------------------------------

             Summary: Running test in Maven is slower than in Ant
                 Key: NETBEANS-4746
                 URL: https://issues.apache.org/jira/browse/NETBEANS-4746
             Project: NetBeans
          Issue Type: Task
          Components: projects - Maven
    Affects Versions: 12.0
            Reporter: Jaroslav Tulach
            Assignee: Jaroslav Tulach
         Attachments: justtest.diff

NetBeans users has just recently complained that Maven support is slower than Ant - some even claimed they [rather maintain dual Ant script support|http://mail-archives.apache.org/mod_mbox//netbeans-dev/202008.mbox/browser] 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:
{code:java}
$ 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
{code}
and you can also run it with Ant:
{code:java}
 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
real    0m1,899s
user    0m4,250s
sys     0m0,244s
 {code}
2.6s vs. 1.9s! Really? Is that the problem? Probably not, I guess the difference is the integration into the IDE then.
