Mockingbird

Before I reinstalled I tried this aswell, but it didnt work

So actually I found the solution. For someone with the same problem: I had jdk version 14, but actually needed version 8. I dont know where exactly the problem was, but for me, reinstalling jdk (this time jdk-8u241) solved everything. And thank you Ugdhar

So I wanted to start with modding, following this tutorial: https://www.youtube.com/watch?v=H55ClYTdQEI. I did everything just like he did, installed jdk, jre and eclipse. Then I opened cmd, cd to the project folder with the unzipped forge 1.15.2 in it. Then typed: gradlew genEclipseRuns and gradlew eclipse. I started Eclipse and imported the Project. I had some Errors in the Project, without knowing what I could have done wrong. was something like: Project 'testmod' is missing required library: 'C:\Users\Username\Desktop\testmod\unresolved dependency - net.minecraftforge forge 1.15.2-31.1.0_mapped_snapshot_20190719-1.14.3'. I reinstalled everything, did all the steps again, and got following "Errors" in cmd I didnt see before: See attached file. Please say if you need anything else. Im sorry if its an obvious Problem, as I said im completely new to this. I dont know if I did anything wrong or how to solve this.mod genEclipseRuns Output.txt
