一、錯誤描述
剛剛完成一個新功能，然後加上了混淆配置，接著Jenkins自動化編譯的時候出錯了，錯誤描述如下所示：

二、解決錯誤
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
看上面的錯誤提示是Proguard在讀取配置檔案 /data/jenkins/workspace/AP_GlobalLoginBindModule/watch/proguard-module.pro 的時候，讀取到142行的時候出現了錯誤，我們來看一看這一行到底有什麼錯誤
# 漢字筆劃排序
-keep com.xtc.watch.view.account.login.utils.stroke.bean.** {*;}
哎，寫的太快了，少寫了一個關鍵字 class，暈死。
立馬修復，將錯誤的keep改為 keep class
# 漢字筆劃排序 -keep class com.xtc.watch.view.account.login.utils.stroke.bean.** {*;}
修改完畢之後，提交程式碼，重新使用Jenkins編譯即可成功！
