The Gradle Daemon is a key performance enhancer, making builds up to 75% faster, but it needed to be explicitly enabled in previous versions of Gradle. This is no longer necessary as the Daemon is now enabled by default in 3.0.

Daemon がデフォルトで起動され, 75% の速度向上らしいので.

Android Studio で使ってみよう

プロジェクトルートの位置で.

./gradlew wrapper --gradle-version=3.0

これで, Gradle 側はラッパーインストールできますが, Android Plugin が 2.1.x系では対応できていないようです.

最新のbetaを入れてみましょう.

com_android_tools_build_gradle

com.android.tools.build.gradle

(project-root)/build.gradle


buildscript {
  //System.properties['com.android.build.gradle.overrideVersionCheck'] = 'true'
  repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.0-beta1'
    }
}

Total time: 6.543 secs
↓
Total time: 1.472 secs

小さいプロジェクトでも, 2回目以降のビルドで, 高速になったことが体感できます.

まあ, beta ということで少し待っていたほうがいいのかも知れませんが.
