Java-导出包含引用库的可运行JAR（错误：清单主属性的签名文件摘要无效）

Question

我找了很多地方，但我没有找到一个对我有帮助的答案。我试图导出一个可运行的JAR，但我的应用程序依赖于Eclipse中Referenced Libraries文件夹中的三个JAR。我尝试了Eclipse为包含jar提供的所有三个选项（“将所需库提取到生成的jar中”、“将所需库打包到生成的jar中”和“将所需库复制到生成的jar旁边的子文件夹中”），但当我运行jar时，如下所示：

java -jar test2.jar

我得到了同样的错误：

在我的lib/meta-inf/manifest.mf中，我有：

大约700行，看起来就像这些，然后在最后我有

Class-Path: C:/Users/luis/workspace/jaf-1.1.1/activation.jar 
C:/Users/luis/workspace/javamail-1.4.7/mail.jar 
C:/Users/luis/workspace/sqljdbc_4.0/enu/sqljdbc4.jar

这是我要包括的三个罐子。有什么想法吗？提前道谢！

Answer 1

乍一看...必须修改当前清单文件，特别是替换从

Class-Path: C:/Users/luis/workspace/jaf-1.1.1/activation.jar
C:/Users/luis/workspace/javamail-1.4.7/mail.jar
C:/Users/luis/workspace/sqljdbc_4.0/enu/sqljdbc4.jar

检查所有换行符/新行/行尾是否为Windows CRLF格式。

在JAR导出过程中，选择“Package required

确保在导出过程中提及新保存的清单。

现在，将引用的库追加到新的jar文件中（例如，拖动引用的jar文件并拖放到yourjarfile上）

签名您的jarfile

 jarsigner "yourjarfile" KeyName -tsa http://timestamp.digicert.com 

对我有用...希望对你有用！
