java - 使用来自 Square 的最新 jar 的问题 - retrofit、okhttp、okio 和 okhttp-urlconnection

Question

我为我正在开发的功能引入了以下 Square jars:

• okttp-2.0.0
• okhttp-urlconnection-2.0.0.jar
• okio-1.0.0.jar
• retrofit-1.6.1.jar

我从中央 Maven 仓库下载了这些。

在本地一切正常，我将我的代码提交给 svn。我们有一个生成调试和发布版本的 Jenkins CI 服务器。这失败了。

我的本​​地环境和 Jenkins 有很多不同:

• 我在本地运行 java 8，Jenkins 运行 java 6
• 在本地我只生成调试版本，Jenkins 生成调试版本和发布版本
• 本地我有构建工具版本 22.6.2，Jenkins 运行 18.0.1

这些是我在 Jenkins 日志中看到的问题:

即使在 Jenkins 上，调试版本也说它通过了但发布版本失败了。问题只是 Proguard 吗？

我确实找到了一些设置，我当前的 proguard 文件有以下关于库的指令:

-dontwarn com.squareup.okhttp.**
-keep class retrofit.** { *; }
-keepclasseswithmembers class * {
@retrofit.http.* <methods>;
}

由于差异如此之大，我正试图找出可能的罪魁祸首!任何想法从哪里开始？如果我可以通过 proguard 更改摆脱困境，我不愿意更改 jenkins 上的配置。

Answer 1

这个问题终于解决了，但需要进行多次更改。

1. 我在运行 Jenkins 的节点上将 jdk 更新为 7。
2. 我更新了android sdk工具

3. 我在混淆器中添加了以下内容:

   -dontwarn com.facebook.android.BuildConfig
   
   -dontwarn rx.**
   
   -dontwarn okio.**
   
   -dontwarn com.squareup.okhttp.*
   
   -dontwarn retrofit.appengine.UrlFetchClient
   
   -keepattributes *Annotation*
   
   -keep class retrofit.** { *; }
   
   -keepclasseswithmembers class * {
       @retrofit.http.* <methods>; 
   }
   
   -keepattributes Signature
