Gradle 知识点

Gradle 简介

官网地址: https://docs.gradle.org

Gradle 默认安装路径

  • C:\Users\username (大微软 Windows)
  • /Users/username (Mac OS X)
  • /home/username (Linux)

常用版本路径(以下为 Mac OS X 平台示例)

  • ~/.gradle/wrapper/dists/gradle-4.4-all/9br9xq1tocpiv8o6njlyu5op1
  • ~/.gradle/wrapper/dists/gradle-4.1-all/bzyivzo6n839fup2jbap0tjew
  • ~/.gradle/wrapper/dists/gradle-3.5.1-all/42vjebfdws9pjts3l4bouoq0p

简单优化

配置全局的 gradle.properties

1. daemon

使 Gradle 启动后常驻后台进程, 避免反复初始化, 加快 Android 项目打包速度.

打开 /Users/.gradle/gradle.properties(没有就创建一个), 添加这一句org.gradle.daemon=true, Save it.

or 来点有逼格的玩法：

  • Windows 下命令行创建该文件, 并添加上述优化内容

    (if not exist "%USERPROFILE%/.gradle" mkdir "%USERPROFILE%/.gradle") && (echo org.gradle.daemon=true >> "%USERPROFILE%/.gradle/gradle.properties")

  • Mac 下命令行创建, 并添加上述优化内容

    touch ~/.gradle/gradle.properties && echo "org.gradle.daemon=true" >> ~/.gradle/gradle.properties

配置本地项目的 gradle.properties

1. JVM 内存

Gradle 的 jvm 的内存分配设置

在 Android 工程里打开 gradle.properties,, 添加org.gradle.jvmargs=-Xmx2048M, Save it.

为什么是 2048M? 可以设置其它值吗?

  1. 这个值是我项目在 Terminal 执行 ./gradlew build 命令时给的提示, 你自己的操作时注意观察一下.
  2. 可以设置其它值，根据机器配置高低不同
