My mod works fine in eclipse , but not when I export it. None of the "import net.minecraft.client.Minecraft" libs can be found and it crashes.

How do you exported your mod? Did you recompile it? Or did you just copied the class files into a .jar archive?

Just in case you did not know that:

gradlew.bat build builds your mod, and places it relative to your workspace in build/libs.

I didn't know that, thank you. but now when i run that, the jar it makes is empty. but the window says seccessful. is there a tutorial on this?

Did you set it to your mod in the build.gradle file? You need to set lines 20-22 to the info relevant to your mod.
