transformClassesWithDexForDebug fails with non-zero exit value 3

Question

I'm compiling multidex project and gradle gives me this:

Execution failed for task ':Project:transformClassesWithDexForLiteDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_31.jdk/Contents/Home/bin/java'' finished with non-zero exit value 3

I suppose it happens because gradle runs out of memory and there are solutions to add:

dexOptions {
    javaMaxHeapSize "4g"
}

But in my case I get another error from gradle: Cannot resolve symbol 'javaMaxHeapSize'.

And it just does not compile. Any help very appresciated!

To me, if you have this kind of error, it is because you misplaced this dexOptions:

What you have to do is to put it as a child of android in your module (I guess called app) gradle file.

Like this:

android {
    signingConfigs {

    }
    compileSdkVersion 23
    buildToolsVersion "23.0.1"
    defaultConfig {

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.Lolo

        }
        debug{

        }
    }
    dexOptions {
        javaMaxHeapSize "4g"
    }
}
