Tricky set-up for Mac OS X (>=1.8) with JDK 1.7

[artheus]

Hey ppl,

 

I just went through a couple of hours debugging the java build of my Minecraft Forge instance.

The I kept getting errors all the time.

 

My suggestion would be to add fixes/patches for the following:

 

1.

First off I kept getting error messages telling me that automatic download of the files `scala-library.jar`and `bcprov-jdk15on-148.jar`was not possible.

I tried then to find out where to download these manually, as the links where clearly broken.

The links I tried was `http://files.minecraftforge.net/fmllibs/{filename}`. I then discovered a forum post where they told others to just add `.stash` to the filename. So for scala-library it would be `http://files.minecraftforge.net/fmllibs/scala-library.jar.stash` and now that worked like a charm!

I just had to add the files to forge/mcp/jars/lib/ and that part was resolved.

 

2.

Next problem was that some of the libs where not compatible with JDK 7 SE ( java version "1.7.0_45" to be specific ).

I got the error

 

_NSJVMLoadLibrary: NSAddLibrary failed for /libjawt.dylib

JavaVM FATAL: lookup of function JAWT_GetAWT failed. Exit

 

So, not so clearly, this had to do with the java version. You should use JDK 6 SE.

What I needed to do to make this work was to edit `forge/mcp/runtime/commands.py` line 789:

 

- self.cmdjava = '"%s"' % os.path.join(results[0], 'java')

+ self.cmdjava = '/usr/libexec/java_home -v1.6.0 --exec=java'

 

After all this, I got to finally compile my client with the mod.

 

Hope this helps someone, and that this can be fixed.

 

Cheers,

Artheus

1) Is intentional, update

2) Not applicable to the new system, and we don't back port things, So no. The only solution you'll get is to update to the new system.

Okay, I can understand that.

But it seems that does not support older versions of Minecraft, like 1.5.2.

 

My use-case is that I would like to create extra mods for a mod package that me and my friends are using.

I guess that this might be a slim use-case for trying to convince you that it might be good to support even older versions. But I am guessing that there might be others trying to do the same thing as me.

 

So my new suggestion being that you could add a small documentation on your site, on "How to do stuffs for the 1.5.2".

 

Might not be a really bad idea, as people would much rather it actually works directly than having to change stuff. But if they are determined on getting it to work for 1.5.2, I guess they'd like a little guidance before having to go through the trouble I went through.

 

If you want, I can write a documentation page for this. I'm more than happy to contribute stuff. ( Documentations, development tools, environmental tools, source code )

How to mod for 1.5.2:

Don't, 1.6.4+ is what you should dev for.
