So I had give IntelliJ a try like about 3 times already, and always have some problem when trying to use it as a Minecraft Development Environment. There is always some issue and I give up and keep using Eclipse.

 

This time I followed yet another Youtube tutorial, and I'm having some issues.

 

When I try to launch MC now I get this error:

Anyone know what could it be that I'm missing. Or anyone has some fools proof tutorial of the step by step on how to set up IntelliJ, it looks like the ones I followed always forget to cover some topic and that makes it so it doesn't work for me.

Thanks a lot.

There's a section about setting up IntelliJ IDEA in the official docs: http://mcforge.readthedocs.io/en/latest/gettingstarted/#terminal-free-intellij-idea-configuration. Give it a try, if it doesn't work, you can always try this tutorial by diesieben07, which should still work:

Thanks a lot. Gonna save that for reference. I just uninstalled IntelliJ, Java JDK and JRE reinstall everything and after another minor bump with IntelliJ trying to "Compile"(?) agains't Java 9 and changing that to Java 8 in 3 different places, I now finally got it to launch

Now let's this experience begin. I have used IntelliJ in the past for Android, but never for MC. Let's see how it goes.

 

Thanks once again.

 

FML isn't compatible with Java 9, which means you can run your dev environment with Java 9 until cpw finished the rewrite of FML.

Thanks. Yes not even sure why this happen, I saw Java 9 but I installed the 8. I guess IntelliJ wanted to check against Java 9 anyway. That fixed it making sure I had selected Java 8 everywhere and finally was able to launch
