[SOLVED] Linking FMP into Eclipse

[toxicwolf]

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?

[luisc99]

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

[toxicwolf]

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?

[larsgerrits]

Do you have scala installed?

[toxicwolf]

I didn't, so I installed Scala, restarted my computer - but same error.

[larsgerrits]

Try installing the scala eclipse plugin.

[luisc99]

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

 

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

[toxicwolf]

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.

[toxicwolf]

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.

[MrNice]

hey i wanted to make some changes got same problem

Using forge xxx.953 unpacking sources, adding eclipse folder as workplace adding in jars/mods/

CCC,CCL, but when mod projectred req FMP it download and always FMP crash
