Posted March 28, 20205 yr 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
March 28, 20205 yr Quote java.lang.IllegalStateException: Could not find tools.jar. Please check that C:\Program Files\Java\jre1.8.0_241 contains a valid JDK installation. Looks like you have your JDK pointing to your JRE. Just to forewarn you, if you do not have previous java experience, modding will be nearly impossible, and only forge is supported on these forums, not basic java.
March 28, 20205 yr Author 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
