Need some help from Java experts. Knowing SCons might help too.

I'm trying to create a top-level jar from other jars and some classes I compiled. I don't want actual jarA in jarB, I want jarA's contents at the top level of jarB. It doesn't seem possible from the jar command itself and that only ant(the build I'm trying to translate into SCons) with <zipgroupfileset> and maven can do this kind of jaring natively.

So, if this isn't possible in SCons or the jar command...is there an elegant way of doing this? SCons is basically Python, so that's what I have available.

As I remember jars are just zip files. Unpack the jars you want to include and put the class files wherever you want and then re-jar all that together. Am I misunderstanding what you want?

No, that's it, was just hoping there was a less manual way. Seems like something that should be more easily automated in popular build systems.

Can you run a script as part of your build process? Seems easy enough to script out the unzip, copy extra stuff and re-jar steps.

Yeah, that parts easy even if it is annoyingly not automated. What I'd really prefer to have automated is the handling of information in META-INF. Did you know you can hide dependencies via the 'Class Path' field in manifest.mf?

I *think* what you're asking for is shading your JAR. Try the maven shade plugin.

Trying not to use another build system if possible. While SCons is great for building everything, it's not great at building everything. For now, we're stuffing all the dependency jars into our third-party folder and I'm going to alter the class-path in the manifest to reference them. Which, of course, I'm now running into some of the silly restrictions Oracle has put on the manifest file. 72 character width...why that specific number?

Can you not call Maven from SCon? I have no experience with it but it sounds like if you're calling java jar you should be able to just call mvn package.

So instead they're telling you to cobble together home made scripts to try and be a ghetto maven? Sounds legit.

Part of the problem is how do you expose dependencies to SCons that maven or ant would inherently handle?

Anyone here familiar with C++ enough to give me some advice on a project? It's a 300 level class on OOP.

I'm familiar with C++, not an expert though. There's bound to be at least a few here. Ask away, I'm sure others will like figuring it out anyway.
