 Description   

From forum post:

I'm trying to commit project specific GRADLE_OPTS for gradlew/daemon into our VCS.

If I'm not missing anything, the best way to currently achieve this is by manually adding them as DEFAULT_JVM_OPTS in both gradlew and gradlew.bat.

But this has the severe downside that those changes will be overwritten whenever the wrapper task is executed. (I never edit the gradle-wrapper.properties manually. I always set the new version in the wrapper task and re-execute it.)

Shouldn't it be possible to either specify the defaultJvmOpts in the wrapper task or load those values from a file that is not created or overwritten by the wrapper task but loaded by the start scripts?

I'd prefer configuration of the wrapper task.

I tend to agree. I end up hacking this in to almost every project I work on.

Here is a workaround to set GRADLE_OPTS after the files have been generated:

def defaultWrapper = tasks["wrapper"]
task wrapper(overwrite: true, dependsOn: defaultWrapper) << {
    def gradleOpts = "-XX:MaxPermSize=1024m -Xmx1024m -XX:MaxHeapSize=256m"
    File wrapperFile = file('gradlew')
    wrapperFile.text = wrapperFile.text.replace("DEFAULT_JVM_OPTS=", "GRADLE_OPTS=\"$gradleOpts \$GRADLE_OPTS\"\nDEFAULT_JVM_OPTS=")
    File wrapperBatFile = file('gradlew.bat')
    wrapperBatFile.text = wrapperBatFile.text.replace("set DEFAULT_JVM_OPTS=", "set GRADLE_OPTS=$gradleOpts %GRADLE_OPTS%\nset DEFAULT_JVM_OPTS=")
}
