初识Gradle系列一

背景

以前听说过Gradle,也查阅过相关资料,自定义生命周期等等,比Maven牛X, 但Maven在项目中已经够用, 所以一直未做构建迁移.

今天业余搞点Android小应用, 经过对比, 最终选择了Android Studio(1.0.3), 该软件默认使用Gradle构建, 在此记录下使用历程及碰到的问题.

安装Gradle

笔者操作系统为Mac, 以下目录采用Mac目录

1. 下载安装包: https://services.gradle.org/distributions/gradle-2.2.1-all.zip
2. 解压
3. 制作超链接

cd /usr/bin
ln -s /Users/arccode/ProgramFiles/gradle-2.2.1/bin/gradle gradle

1. 查看版本号: gradle -v

新建HelloWorld

使用Android Studio按照提示完成HelloWorld App的建立.

Gradle使用

尝试使用gradle来构建App.

问题

• 执行命令gradle clean报错,

FAILURE: Build failed with an exception.

* Where:Build file '/Users/arccode/AndroidStudioProjects/HelloWorld/build.gradle' line: 5* What went wrong:A problem occurred evaluating root project 'HelloWorld'.> Could not find method jcenter() for arguments [] on repository container.* Try:Run with --stacktrace option to get the stack trace.

BUILD FAILED

老版本bug, 使用gradle-2.2.1无此问题.

• 没找到gradle build后生成的apk包(汗, 😓),

项目的根目录下有build目录, 但gradle构建生成的目录默认放在app/build, 所有生成的apk包也在app/build目录下.
