So, I just downloaded Java Eclipse IDE (latest version) and decompiled MCP (Minecraft) then opened it in Eclipse, fixed the errors then ran it. Then I get this error, can somebody help? https://gyazo.com/bc4ba064b31d5958fed3ca2f5a9a633e
My Java Memory settings are: -Xincgc -Xmx1024M -Xms1024M
which leads to the error Unrecognized option: -Xincgc
. What VM settings should I use instead?
