android - How to solve the ionic build error "java heap space"?

Question

I have a ionic project. The app was build and run in my android phone successfully before. But suddenly from someday, when I run command "ionic cordova run android" I get the build error as below:

Execution failed for task ':transformClassesWithDexForDebug'. com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: Java heap space

I have tried "cordova clean" to synchronise the cordova plugin. But it doesn't work..

How to solve this problem?

Answer 1

Open gradle.properties under your project root directory and add/modify below line to

org.gradle.jvmargs=-Xmx3536m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError

Specifies the JVM arguments used for the daemon process. The setting is particularly useful for tweaking memory settings. Change -Xmx3536m to a larger value if this still does not meet your requirement.

And, modify your module level build.gradle

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