    Hi! I'm starting in the world of mod development for minecraft but I'm having a problem in which I can't get minecraft to run directly through eclipse whenever I trigger the error:
    Picked up _JAVA_OPTIONS: -Xmx512M
    [08:53:53] [main/INFO] [LaunchWrapper]: Loading tweak class name cpw.mods.fml.common.launcher.FMLTweaker

    So, have any of you ever faced something like that? I have already mapped the two versions of java on my machine (8u271 and 8u202) but it seems to me that the "main class" argument is not fulfilling its service the arguments are as follows:

    Main Class: 
    net.minecraft.launchwrapper.Launch
    
    Program Arguments:
    --version 1.12.2 --tweakClass cpw.mods.fml.common.launcher.FMLTweaker --username [my personal mojang login username] --password [my personal mojang login password]
    
    VM Arguments: 
    -Dfml.ignoreInvalidMinecraftCertificates=true

     My minecraft runs perfectly on the machine. Currently I have installed on my machine jdk and jre 8u202 / 8u271 and jre integrated with curseforge / overworlf I would appreciate it very much if you could help me! I look forward to starting coding! xD
