當我使用proguard生成發行版APK時出現錯誤

Question

如何解決這個錯誤？

Warning:com.parse.ParseOkHttpClient: can't find referenced class com.squareup.okhttp.Headers

Warning:com.ocpsoft.pretty.time.web.jsf.PrettyTimeConverter: can't find referenced class javax.faces.context.FacesContext

Warning:Exception while processing task java.io.IOException: Please correct the above warnings first.

Error:Execution failed for task ':project1:transformClassesAndResourcesWithProguardForRelease'.<br>
 java.io.IOException: Please correct the above warnings first.

將此添加到項目中的proguard-rules.pro文件中：

-keep class com.squareup.** {*;}
-dontwarn com.squareup.**
-keep class com.ocpsoft.** {*;}
-dontwarn com.ocpsoft.**
