Gradle build incredibly slow

Question

Build time right now is ranging around ~2-4 min.

I'm using about 11 libraries provided via Gradle.

I have the following set:

buildTypes {
    debug {
        multiDexEnabled = true
        applicationIdSuffix ".debug"
        minifyEnabled false
        proguardFile 'proguard-rules.pro'
    }
}

dexOptions {
    javaMaxHeapSize "4096M"
    preDexLibraries false
    jumboMode = true
    incremental = true
}

Gradle: Offline mode

I have the following setting in gradle.properties org.gradle.jvmargs=-Xmx4096m -XX:MaxPermSize=1024m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

In the global properties I have:

org.gradle.daemon=true
org.gradle.parallel=true
org.gradle.configureondemand=true

I've looked through about every article I can find on it on Google/Stackoverflow.

Is there any way to speed the process up to below 1 minute at least?

These really helped speed things up for me.

gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-2.5-all.zip

build.gradle project dependencies

classpath 'com.android.tools.build:gradle:1.3.0'

I've found that as it turns out using Protoc is very very slow for Android. I switched to Wire and it took the compilation time from 2 min. to 10s-30s.

Answer 1

I found that multiDexEnabled = true makes my build process extremely slow. I don't know if it's possible to improve it's performance somehow, but for now I just turned it off.

You have to use it only if amount of methods in your project (including libraries) goes beyond 65k limit. Maybe you can cut off some of your 11 libraries, then turning off multiDexEnabled option should solve your problem.

You can also upgrade gradle by editing the gradle-wrapper.properties file and set gradle-2.4-all.zip
