[SOLVED] Linking FMP into Eclipse

Posted November 1, 201311 yr

I am trying to use ChickenBones' ForgeMultipart (which requires ChickenCodeLib) and need to link these external libraries into eclipse so I can develop my mod using them.

I've already searched Google and these forums but haven't found anything that works for me yet.

I have tried putting the jars into the mcp/lib folder and then linking them in eclipse and referenced libraries, which allows me to write code that imports classes, however when I run Minecraft from eclipse, the coremods contained in these libraries do not get loaded.

Can someone point out where I'm going wrong?

In the run configuration to need to specify to use those external jar files. That's what fixed it for me anyway...

Ah yes, thank you! I had totally forgotten about that step.

EDIT: Now I'm getting errors Do I need to install the Scala eclipse plugin?

Do you have scala installed?

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

Try installing the scala eclipse plugin.

I have installed the Scala IDE eclipse plugin (I hope that's the one you meant) but again, same error.

http://files.minecraftforge.net/fmllibs/scala-library.jar

Do you have that in your mcp/jars/mods directory?

No I don't, and I can't find the exact file you're referencing anyways, since the link takes me to a 404.

I appreciate both of your efforts to help me, regardless

EDIT: So just to check, I set up a normal minecraft instance with Forge, CCL, CCC and FML. It runs fine.

I then tried adding them to the mcp/jars/mods folder and removing the dev versions from my run config in eclipse; it throws the error. I wonder if this helps?

I did previously set this up on a different computer, but I cannot remember what I did differently/ how I got it to work.

Solved. I should note that I set up my dev environment the "Pahimar way" and therefore was using his Minecraft-Project-Eclipse github repo, see my pull request on there to see how I fixed my issue.

To clarify: it was not necessary to install Scala or the Scala IDE eclipse plugin.

Sorry for necro, but this is one of the first search results for this issue. Possible cause is Forge checking for zlib (the expected hash) and not accepting zlib-ng (the actual hash):

https://github.com/PrismLauncher/ForgeWrapper/issues/3

One possible workaround (aside from swapping zlib-ng for zlib which might cause other problems on your system) would be to use the prism flatpak.
