Minecraft won't start through Eclipse

[veky]

Hey guys,

 

I wanted to get familiar with minecraft modding and while trying to set up everything, I tried to run Minecraft through Eclipse (runClient). The FML early loading progress shows up, then Minecraft pops up for a second and closes right after.

 

I only modified the Example.java and mods.toml so the Mod-Tag and the modId are the same so far.

Thank you very much. I installed AdoptOpenJDK 8 now and it's working just fine.
