Building project: outOfMemory (Android studio 3.4)

Question

I've upgraded Android Studio 3.x to 3.4 (with Grade plugin), and now, the build of my project is very very very long, and there is a final error (after 4-5mins of building):

> Task :app:compileDevelopmentDebugJavaWithJavac
Gradle may disable incremental compilation as the following annotation processors are not incremental: butterknife-compiler-10.1.0.jar (com.jakewharton:butterknife-compiler:10.1.0), esperandro-2.6.0.jar (de.devland.esperandro:esperandro:2.6.0).
Consider setting the experimental feature flag android.enableSeparateAnnotationProcessing=true in the gradle.properties file to run annotation processing in a separate task and make compilation incremental.
Note: [1] Wrote GeneratedAppGlideModule with: [com.bumptech.glide.integration.okhttp3.OkHttpLibraryGlideModule]
warning: No SupportedSourceVersion annotation found on de.devland.esperandro.processor.EsperandroAnnotationProcessor, returning RELEASE_6.
warning: Supported source version 'RELEASE_6' from annotation processor 'org.gradle.api.internal.tasks.compile.processing.TimeTrackingProcessor' less than -source '1.8'


The system is out of resources.
Consult the following stack trace for details.
java.lang.OutOfMemoryError: GC overhead limit exceeded
    at java.lang.StringCoding$StringEncoder.encode(StringCoding.java:300)
    at java.lang.StringCoding.encode(StringCoding.java:344)

Before this upgrade (done this morning), all works perfectly. Have you got some investigation ways please?

build.gradle:

buildscript {
    repositories {
        google()

        jcenter()
    }

    dependencies {
        // https://developer.android.com/studio/releases/gradle-plugin.html
        classpath 'com.android.tools.build:gradle:3.4.0'

        // https://developers.google.com/android/guides/google-services-plugin
        classpath 'com.google.gms:google-services:4.2.0'

        classpath 'com.google.firebase:firebase-plugins:1.2.0'

        // https://github.com/JakeWharton/butterknife
        classpath 'com.jakewharton:butterknife-gradle-plugin:10.1.0'
    }
}

gradle-wrappers.properties:

distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-all.zip

Increase the memory available to Gradle build system.

Put this in your gradle.properties file:

org.gradle.jvmargs=-Xmx2g

mx means max memory, 2g means two gigabytes.

If there already is a org.gradle.jvmargs add -Xmx2g at the end. Remove the old -Xmx if there is any.

You shouldn't need more than three gigabytes for your app. Adding more gigabytes doesn't necessarily give better performance.

Try options.forkOptions.setMemoryMaximumSize("2g") if you are also using options.fork.

For me, org.gradle.jvmargs or javaMaxHeapSize does not work. So I commented out lots of gradle script commands to diagnose which cause the problem, and found options.fork.

ps. Removing options.fork also works.
