Hmm okay just ran the gradlew eclipse command, opened eclipse and now i can see some source files. all good, opened the same file back in netbeans and that is linked perfect as well.
Name forge-1.14.3-27.0.20_mapped_snapshot_20190704-1.14.3
file : GLX from pacage package com.mojang.blaze3d.platform;
[Removed]
that is all good and pretty, however
some other files under package net.minecraft.state for example is still the compiled jiberish.
[Removed]
im calling it a nigth and concluding that the mapper and forge it self is still in beta and i should properly wait untill a stable release, thank a lot guys i learned some new thing here that hopefully will make the error fixing easyer in the future.
