How can I run multiple Main classes from one jar file at once (parallel)

Take a look at http://stackoverflow.com/questions/3774432/starting-a-process-in-java . Or just Google starting a process in Java. — David says Reinstate Monica, Nov 10 '13 at 18:55

As of Gradle 1.9, Gradle can only run task from different projects in parallel. You can implement your own task and execute the main methods in parallel within that task, possibly using the Project.javaexec() method. However, you'll have to implement this yourself, for example with the GPars library.
