如何使用嵌套的JAR库生成java库？

Question

I need save my application, that included external JAR libraries, in single JAR file for future use as single lib. When I export it to JAR file, all nested jars append to archive, but not work as part of single lib. What I do wrong?

How can I make nested libraries private for external application?

Answer 1

I think jars in a jar is not supported. But you can always extract the external JAR libraries and than create a jar containing their content and your classes in one jar.

This way you can also remove the parts of the external libraries, you don't need, to reduce the size of the jar you create.

Answer 2

Single Executable jar with all dependency nested is not possible by standard jar making process. Alternatively you can place all dependent jars in a folder parallel to your own executable jar.

There is another way to create Single Jar with all nested dependent jar with the help of One-Jar . I personally never tried this.

Hope this helps.
