Custom modpack wont run

[K1ngD3rp]

Ive been working on making a modpack, with a couple of friends. This pack is in 1.12.2, and it runs for the other two, and I can run other modpacks, but anytime I try and run our pack nothing happen, it just reopens the launcher.
I have the logs but they are to large to use in pastebin.

No clue what to do ¯\_(ツ)_/¯

Just open the logs, copy paste the second half, try to pastebin that.

You are on Java 7, while modpacks require java 8 nowadays. If version is a problem, download 8u25.
