Android - Proguard返回错误代码1

Question

我希望我的应用程序受到progaurd保护。为此，我去将向您介绍一些教程，职位和从this帖最后我才知道，我只能这样做：

If you're using ADT 17 or newer, the documentation is slightly inaccurate. The generated file is proguard-project.txt and will be in the root directory of your project. 

To enable Proguard, you will need to ignore the "do not modify" warning in project.properties and uncomment the following line: 

proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt 

uncommeting上述建议行我试图出口未签名应用后。但有一个出口错误说progaurd returned error with code 1。当我点击了错误对话框中的详细信息按钮，我得到了如下图所示的错误日志：

Proguard returned with error code 1. See console

任何想法，为什么会出现这种情况？我正确配置progaurd或错过了步骤？

Answer 1

的根本原因是在堆栈跟踪上市：

Caused by: java.io.IOException: Can't read [C:\Users\SURESH\Desktop\ActionBarSherlock-4.2.0\ABSlibrary\bin\abslibrary.jar] (Unexpected end of ZLIB input stream) 
... 
Caused by: java.io.EOFException: Unexpected end of ZLIB input stream 
    at java.util.zip.InflaterInputStream.fill(InflaterInputStream.java:223) 
    ... 

您应检查以下内容：

• 本在指定的位置文件abslibrary.jar？
• 它是一个有效的jar（你可以用一些解压缩工具打开它）吗？
• 它是在编译过程中写入的吗？如果以某种方式异步写入，ProGuard读取它时可能仍然不完整。

Answer 2

我通过关于无法找到的jar的注解-libraryjars来解决这个问题。文件说不会出现jar，它会在运行时加载jar。
