====== Gradle ======

[[wiki>Gradle|Gradle]] 是一个Android常用的项目自动化建构工具。

===== Proxy =====

Gradle从bintray.com下载文件**非常慢**，可设置代理加速下载[(cite:>[[https://www.zhihu.com/question/37810416/answer/82464203|大家都是怎样处理Gradle中的这个文件下载慢的问题的？]])]：

<code ini $HOME/.gradle/gradle.properties>
org.gradle.daemon=true
org.gradle.jvmargs=-DsocksProxyHost=127.0.0.1 -DsocksProxyPort=1080
</code>

===== Usage =====

''Gradle'' 默认读取当前目录下的 ''build.gradle'' 文件。

列出所有任务：

  gradle tasks
