Здравствуйте, народ! Мне посоветовали Eclipse, и я теперь не могу понять его. Я говорю: File — New — Java Project — ProjectName=Hello — Finish — File — New — Class — Helloworld — ставлю галку рядом с void main(String[] args) — Finish — пишу в main’е System.out.print(2+2);
Результат: Errors exist in required project(s):
Hello
Proceed with launch?
Я нажимаю proceed. Вылезает следующее: ‘Launching Helloworld’ has encountered a problem. The specified JRE installation does not exist.
Хотя у меня есть и JRE и JDK. Помогите, пожалуйста, в чем проблема?

Java-машину устанавливали ПЕРЕД установкой Эклипса?

посмотрите, куда в Эклипсе сохраняются Ваши проекты. И затем, соответственно, что там находится.

This is probably caused because you have somehow altered the «minecraft.jar,» and Eclipse needs to rebuild the Environment but it doesn’t know it. Whenever this happens to me, I just restart Eclipse, or sometimes I’m lucky and it automatically rebuilds the environment.

You may need to reinstall eclipse, create a new workspace, or I don’t know what else could’ve happened for this error to appear, so you may need to re-decompile Minecraft and start over.

idk, you might want to search online a bit more before restarting. It’s just an eclipse glitch.

You go inside your mcp folder and open the src and eclipse, and go to the folder that has ibmx and all in the both (src and eclipse), then you pick up all the files from the src and past in the eclipse
Remembering, not the folder, the content, for exemple the ibmx, the folder with your mod .java’s …
If you are with the same error as me, your eclipse folder will be reset, check it, then you choose if you do it or not, its for your own risk man

See ya

the folders in the eclipse ibmx are .class and the ones in src are .java.
