Ubuntu环境安装Gradle

AndroidStudio使用全新的构建系列—–Gradle。

这是官方为什么使用gradle 的理由：

• Domain Specific Language (DSL) to describe and manipulate the build logic
• Build files are Groovy based and allow mixing of declarative elements through the DSL and using code to manipulate the DSL elements to provide custom logic.
• Built-in dependency management through Maven and/or Ivy.
• Very flexible. Allows using best practices but doesn’t force its own way of doing things.
• Plugins can expose their own DSL and their own API for build files to use.
• Good Tooling API allowing IDE integration

在Ubuntu安装Gradle也是很简单。切记请勿使用apt-get安装Gradle。因为Ubuntu源的Gradle实在太旧。我用的搜狐的源，竟然是2011年。

下面是安装步骤：

1. 在官网下载最新的Gradle版本。http://www.gradle.org/downloads
2. 解压安装包到目录
3. 打开环境文件
   

   sudo nano /etc/profile

4. 写入环境变量:
   

   #GRADLE_HOME是Gradle的所在目录

   GRADLE_HOME=/opt/gradle/gradle-1.4

   export GRADLE_HOME

   PATH=$GRADLE_HOME/bin:$PATH

   export PATH

5. 环境变量生效source /etc/profile
6. 检查结果
   

   gradle -v
