安卓自动化之旅（三）——尝试使用Docker环境来构建APK 上

[soapgu]

• 起因

  原因是在上一篇里面，在coding自动化构建尝试升级Gradle版本到7，彻底失败。由于腾讯的主机把http的源配置进去了。然后在Gradle初始化环境的时候直接报错。
  后续发工单找客户询问，经过几轮答非所问以后，客服建议用Docker来构建。不得不说起码最后一条还是一条很有启发性的建议。
  

• 过程

1. 装Docker
   首先我需要在本机安装Docker。过程不表。很久没玩了，windows docker的图形化界面做得好多了
   

2. 找Docker基础镜像
   gradle的环境需要是JAVA的环境。gradle wrapper是会自动安装的
   所以从JRE镜像着手。
   先本机查看 JAVA -version
   openjdk:11.0.10-jdk-buster
   
   找了一个和本机版本一致的

3. 写一个安卓程序
   DockerBuildApk
   一个空的app，使用gradle版本7.0.2

gradle-wrapper.properties

#Wed Aug 04 14:45:37 CST 2021
distributionBase=GRADLE_USER_HOME
distributionUrl=https\://services.gradle.org/distributions/gradle-7.0.2-bin.zip
distributionPath=wrapper/dists
zipStorePath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME

4. Build Docker
   为了保证代码文件时干净的，我用git clone后的文件夹作为Build根目录。不再用Android Studio打开

Dockerfile

FROM openjdk:11.0.10-jre-buster AS base

RUN mkdir /andriod
WORKDIR /andriod
ADD . /andriod
RUN chmod +x ./gradlew

docker build -t soapgu/androiddockertest:v1.0 .

5. Run Gradle
   先小试牛刀，跑个gradle version试试

PS D:\WorkSpace\PlayPen\DockerBuildApk> docker run -it  soapgu/androiddockertest:v1.0 ./gradlew -version
/usr/bin/env: ‘sh\r’: No such file or directory

是吧了，这个报错是什么鬼

PS D:\WorkSpace\PlayPen\DockerBuildApk> docker run -it  soapgu/androiddockertest:v1.0 ls /andriod
Dockerfile  build.gradle  gradle.properties  gradlew.bat
app         gradle        gradlew            settings.gradle

问题文件确实存在的
还是StackOverflow比较厉害

Error with gradlew: /usr/bin/env: bash: No such file or directory

The problem's cause was that Git on Windows converted the line endings of gradlew from Unix style (LF) to Windows style (CRLF).

用notepad++转

BUILD FAILED in 4m 34s

本来想一鼓作气的。结果还是太乐观，Gradle在下完依赖后就构建失败了，缺了Android的SDK环境。
以前都是装Android Studio自动全配好的没有关注这一块（IDE也害人啊，离开就是残废啊）。Anyway，开局还行。
Dockfile还要重做，下一篇 我们来解决Android编译环境的问题
