Question

我在Android应用中使用“jackrabbit-webdav-2.2.5-jar-with-dependencies.jar”。我自己构建了它，只要我直接从eclipse调试或运行应用程序，一切正常。此外，当我将应用程序导出为没有Proguard的“已签名的应用程序包”以便在任何设备上安装时，everthing工作正常。

但是当使用Proguard（java混淆器）时会启动问题。以下是控制台的快照：

我尝试了几个proguard标签，但没有帮助。似乎proguard需要在类路径中明确地需要所有依赖项。也许问题必须用maven解决？（我不是使用maven的专家 - 我尝试了几件事，但他们没有帮助。）

有人也有这样的问题吗？有任何建议或提示如何解决？

提前致谢！约翰

Answer 1

ProGuard确实需要其静态分析的所有依赖项。但是，可能从未使用过丢失的类，因此您可以告诉ProGuard忽略它们：

-dontwarn javax.jcr.**
-dontwarn org.slf4j.**

请参阅ProGuard手册＆gt;疑难解答＆gt; Warning: can't find referenced class

Android和Proguard与jackrabbit-webdav：Proguard返回错误代码1.请参阅控制台
