一、错误描述

刚刚完成一个新功能，然后加上了混淆配置，接着Jenkins自动化编译的时候出错了，错误描述如下所示：

Warning: Exception while processing task java.io.IOException: proguard.ParseException: Unexpected keyword 'com.xtc.watch.view.account.login.utils.stroke.bean.**' in line 142 of file '/data/jenkins/workspace/AP_GlobalLoginBindModule/watch/proguard-module.pro'
:watch:transformClassesAndResourcesWithProguardForRelease FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':watch:transformClassesAndResourcesWithProguardForRelease'.
> Job failed, see logs for details

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

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':watch:transformClassesAndResourcesWithProguardForRelease'.

二、解决错误

Caused by: proguard.ParseException: Unexpected keyword 'com.xtc.watch.view.account.login.utils.stroke.bean.**' in line 142 of file '/data/jenkins/workspace/AP_GlobalLoginBindModule/watch/proguard-module.pro'
    at proguard.ConfigurationParser.unknownAccessFlag(ConfigurationParser.java:1123)
    at proguard.ConfigurationParser.parseClassSpecificationArguments(ConfigurationParser.java:606)
    at proguard.ConfigurationParser.parseKeepClassSpecificationArguments(ConfigurationParser.java:535)
    at proguard.ConfigurationParser.parse(ConfigurationParser.java:164)
    at com.android.build.gradle.internal.transforms.BaseProguardAction.applyConfigurationFile(BaseProguardAction.java:146)
    at com.android.build.gradle.internal.transforms.ProGuardTransform.doMinification(ProGuardTransform.java:244)
    ... 5 more

看上面的错误提示是Proguard在读取配置文件 /data/jenkins/workspace/AP_GlobalLoginBindModule/watch/proguard-module.pro 的时候，读取到142行的时候出现了错误，我们来看一看这一行到底有什么错误

在这里插入图片描述

  # 汉字笔划排序
  -keep com.xtc.watch.view.account.login.utils.stroke.bean.** {*;}

哎，写的太快了，少写了一个关键字 class，晕死。
立马修复，将错误的keep改为 keep class

在这里插入图片描述

# 汉字笔划排序
-keep class com.xtc.watch.view.account.login.utils.stroke.bean.** {*;}

修改完毕之后，提交代码，重新使用Jenkins编译即可成功！
