args 'something somethingelse'
jvmArgs = ['-Xmx12g']

classpath
classpath = sourceSets.main.runtimeClasspath
classpath = configurations.runtimeClasspath
main
The main class. Must be available on classpath.
main = 'playground.javaExec.Main'
args
"args" can be provided as a single string, but in this case, even if individual tokens are separated by space, the main() method will get just one single string as argument:
args 'A B C'
This will be passed to the Java main() method as args[0].
