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 vim /etc/profile

4、写入环境变量:

export GRADLE_HOME=/opt/gradle/gradle-2.0
export PATH=$GRADLE_HOME/bin:$PATH

5、环境变量生效source /etc/profile

6、检查结果

gradle -v
