android 使用Jenkins打包遇到的问题

使用Jenkins持续集成时运行遇到的问题总结

Build step 'Invoke Gradle script' changed build result to FAILURE

Build step 'Invoke Gradle script' marked build as failure

Finished: FAILURE

解决：

这个gradle的配置不对。进入项目的详情页，点击设置，找到“构建”那里的Invoke Gradle script，设置为：Use Gradle Wrapper，然后task里输入build。最后保存。

问题二

’Users/wys/Library/Android/sdk’ not exist

在这里插入图片描述

Google 了一下原因：是由于文件权限的问题
https://stackoverflow.com/questions/39568402/jenkins-giving-the-sdk-directory-doesnt-exist#comment66465785_39568402

设置的路径是Android Studio sdk的默认路径 Users/***/Library/Android/sdk，Library目录是系统的目录，没有读取Library 目录的权限，所以导致失败。

解决办法：

• 添加权限：
  通过终端进入Library目录

  执行 chmod -R 777

  或者 sudo chmod -R 777

• 把sdk换个目录存放 。

问题三：

* What went wrong:
Execution failed for task ':app:lint'.
> Lint found errors in the project; aborting build.

  Fix the issues identified by lint, or add the following to your build script to proceed with errors:
  ...
  android {
      lintOptions {
          abortOnError false
      }
  }
  ...
 
  Errors found:
 
  /Users/Shared/Jenkins/Home/workspace/test/app/build.gradle: Error: All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 28.0.0-alpha1, 28.0.0. Examples include com.android.support:support-media-compat:28.0.0-alpha1 and com.android.support:animated-vector-drawable:28.0.0 [GradleCompatible]  

从log 理可以看出，是由于引入的库版本不一致造成的，解决方法可以是：

添加：

 android {
      lintOptions {
          abortOnError false
      }
  }
 

或者修改一致版本

问题四

这个问题是自己忘了配置打包环境。。。

Build step 'Invoke Gradle script' changed build result to SUCCESS
[WanAndroid] $ echo '"resolving effective environment"'
ERROR: Build step failed with exception
java.lang.NullPointerException

    at hudson.model.Executor.run(Executor.java:429)
Build step 'Sign Android APKs' marked build as failure
Finished: FAILURE

在android gradle下：

signingConfigs {
    release {
        keyAlias '*****'
        keyPassword '****'
        storeFile file('****')
        storePassword '***'
    }
}

问题五 配置打包后文件

在项目配置中

Jenkins 构建后操作 -- Archive the artifacts

在这里插入图片描述
在这里插入图片描述

构建完成后的控制台会显示出构建成功的apk文件

在这里插入图片描述
希望能够帮到遇到相同问题的小伙伴～～～
