Java 使用来自Square-Reformation、okhttp、okio和okhttp urlconnection的最新JAR时出现问题

我为正在开发的功能引入了以下方形罐：

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

我从中央maven repo下载了这些

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

我当地的环境和詹金斯有很多不同之处：

• 我在本地运行Java8，Jenkins运行Java6
• 在本地，我只生成调试版本，Jenkins同时生成调试版本和发布版本
• 在本地，我有22.6.2版的构建工具，Jenkins运行18.0.1

这些是我在詹金斯日志中看到的问题：

即使在Jenkins上，调试版本也表示它通过了发布版本，但失败了。这个问题只是个未知数吗

我确实找到了一些设置，我当前的proguard文件有以下关于LIB的指令：

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

-dontwarn com.squareup.okhttp**
-保持类更新。**{*；}
-keepclassswithmembers类*{
@http.*；
}

有这么多不同之处，我正试图找到可能的罪魁祸首！你知道从哪里开始吗？如果我可以不做任何改动的话，我很不愿意更改jenkins上的配置。

更新你的dx，这是你android SDK的一部分。

这最终解决了，但需要多次更改

我在运行Jenkins的节点上将jdk更新为7

我更新了android sdk工具

我在proguard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

-dontwarn com.facebook.android.BuildConfig
-dontwarn rx**
-唐特沃恩·奥基奥**
-dontwarn com.squareup.okhttp*
-dontwarn改装.appengine.UrlFetchClient
-keepattributes*注释*
-保持类更新。**{*；}
-keepclassswithmembers类*{
@http.*；
}
-保留署名

添加-dontwarn java.util.zip.*和-dontnote java.util.zip.*对我来说很有用
