在服务器上使用 gradle 打包 android 源码

安装 android-tools

mkdir ~/android && cd ~/android

wget https://dl.google.com/android/repository/tools_r25.2.3-linux.zip
unzip tools_r25.2.3-linux.zip

配置环境变量

echo 'export ANDROID_HOME=~/android' >> ~/.bashrc
echo 'export PATH=${ANDROID_HOME}/tools/bin:$PATH' >> ~/.bashrc
source ~/.bashrc

以编译 https://github.com/drakeet/Ti... 为例

git clone https://github.com/drakeet/TimeMachine.git
cd TimeMachine
./gradlew build

漫长的等待后错误如下：

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':timemachine'.
> You have not accepted the license agreements of the following SDK components:
  [Android SDK Build-Tools 25.0.2, Android SDK Platform 25].
  Before building your project, you need to accept the license agreements and complete the installation of the missing components using the Android Studio SDK Manager.
  Alternatively, to learn how to transfer the license agreements from one workstation to another, go to http://d.android.com/r/studio-ui/export-licenses.html

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Total time: 2 mins 40.822 secs

可以看出是因为缺少 [Android SDK Build-Tools 25.0.2, Android SDK Platform 25]
这时执行android list sdk --all 寻找匹配的序号

从上图可以看出匹配的是 3
执行 android update sdk -u -a -t 3 询问时输入 "y" 并耐心等待

额... 好像 gradle 进程被杀了,可能我内存太小了吧, 下次换个大点的再试
