Ant With Internal Dependencies

Question

I have a a jar right now that uses external dependencies. I'm trying to create a jar that packages all the external dependencies inside, and will just give me one jar. I saw this question asked multiple times, but I still can't figure it out. I'm using Ant, and copied some of the examples I saw on here. I'm using zipgroupfileset to reference the external(now internal) jars. As soon as I added the zipgroupfileset I got a runtime error that said my Runner class could not be found.

Answer 1

To make things simpler:

• Create a separate sources jar for compilation. Then, have a separate compiled jar without the sources.
• Don't include the third party jars. Instead, use Ivy with Ant. Ant will automatically download the required jars. In fact, I've see sources that just include the ivy.jar, so Ivy will automatically be configured when you unjar the sources. You type in ant, and everything just builds.

As an alternative, you can look at Maven which is how many projects are now packaged. In fact, if your jar is an open source project, you can probably host it on the OSS Maven repository. This way, no one even needs to manually download your compiled jar. If they want it, they configure their Maven project to do it for them.

Answer 2

i think the problem is that you use basedir="bin" in the your jar task. then path of your zipgroupfileset convert to bin/${external-lib-dir}
