How to Increase the Memory that's available to gradle

Question

In the official post detailing the features of the stable release of Android Studio 2.1, I came across this:

We are also speeding up build times by using in-process dex, which converts class files to dex files within the Gradle daemon process. This avoids the costly processing operation of creating separate dex processes. To use this feature, you will need to increase the amount of memory available to the Gradle daemon to at least 2GB (1 GB is the default).

Please, how can I increase the memory that's available to Gradle?

In Android Studio 2.1 open your gradle.properties file. Find the line

\# org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

Uncomment the line. Gradle was faster after I did this.

In your app's build.gradle file, add the following:

android{
     //....
     dexOptions {
        javaMaxHeapSize "2g"
    }
}

Is there any way to use this as settngs, not to add to every project? – Marko Niciforovic May 12 '16 at 18:11

I have not try this but it should works:

In graddle.build file:

apply plugin: 'java'

compileJava {
    //raise heap
    options.fork = 'true'
    options.forkOptions.with {
        memoryMaximumSize = '2048m'
    }
}

If it does not work in Windows try to add it to a new file gradle.properties next to gradle.build

small nitpick but your quotes are stylized quotes and not standard ASCII quotes. makes for bad copy-paste. – fIwJlxSzApHEZIl Apr 18 '17 at 00:11
