Question

我看了很多，但我找不到能帮助我的答案。我正在尝试导出Runnable JAR，但我的应用程序取决于我在Eclipse的Referenced Libraries文件夹中的三个JAR。我已经尝试了Eclipse提供的所有三个选项，包括JAR（“将所需的库提取到生成的JAR中”，“将所需的库打包到生成的JAR中”，以及“将所需的库复制到生成的JAR旁边的子文件夹中”）但是我像这样运行我的罐子：

java -jar test2.jar

我得到同样的错误：

在我的lib / META-INF / MANIFEST.MF中我有：

Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.2
Created-By: 16.2-b04 (Sun Microsystems Inc.)

Name: com/microsoft/sqlserver/jdbc/SQLServerException.class

大约700行看起来像这些然后最后我

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

我想要包含哪三个JAR。有任何想法吗？提前谢谢！

Answer 1

On First Glance ...您当前的Manifest文件必须进行修改，尤其是从以下开始替换最后几行

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

一个CRLF ...

检查所有换行符/新行/行结尾是否为Windows CRLF格式。

在JAR导出期间，选择＆＃34;打包所需的库＆＃34;

确保在导出期间提及新保存的清单。

现在将引用的库附加到新的jar文件中（即拖动引用jar文件并在yourjarfile上删除）

签署你的jar文件

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

它对我有用...希望它适合你！
