I'll come straight to the point. Forge 1.12.2 - 14.23.5.2855. IntelliJ IDEA. Windows 10. Laptop. My problem is the following one. """ [Client thread/ERROR] [FML]: There was a problem reading the entry module-info.class in the jar C:\Users\Liplum\.gradle\caches\modules-2\files-2.1\org.ow2.asm\asm-analysis\6.2\c7d9a90d221cbb977848d2c777eb3aa7637e89df\asm-analysis-6.2.jar - probably a corrupt zip net.minecraftforge.fml.common.LoaderException: java.lang.IllegalArgumentException """ My TWO FRIENDS who use IDEA and forge 1.12.2 on the laptop AND I ALL meet it. When your Minecraft loads at 1/7 (Loading - Consturcting Mods) and 3/5(Consturction - Forge Mod Loader) , it will crash and leave a lot of error outputs but that one is the most special identifier. I don't know why and then search for it on google. And I've got two identical posts and translated them by google. French one:https://www.minecraftforgefrance.fr/topic/6416/erreur-de-lecture-de-class-dans-les-sources-de-minecraft Chinese one:https://v2mcdev.com/posts/715.html They all had the same problem in their programming on IDEA with Forge 1.12.2.

THANKS!!! It solved my problem bothering me for a long time in version 1.12.2. It's exactly as you said, I used the Eclipse to program formerly.

Thanks. I get it. But I still have 2 question. First, Is the change permanent? When the Minecraft 1.17 comes, I think lots of modders need adapt it. And then I have got to do as well. Second, Will the old mappings be still supported in the future? If not, for the portability, I need learn new mappings instantly. Well, by the way,there're two difficulties for me -- where can I learn the new mappings because the website doesn't provide; new-version forge provides a lot of hardcore premeters such as p_11111_11(is it a point?). Edited: Thank you. I've searched for Minecraft Forge Mappings on Google and now I know what it's and how to work.

After downloading the 1.16.5-36.1.0 version, I found that there were some changed APIs. For instance, In Item class, "use" replaces "onItemRightClick". In World class, "isClinetSide" replaces "isRemote". I've just started to program a mod so that I refer to some other famous mod such as TwilightForest and TConstructure (they are all 1.16.5 version but old). Their codes used old version of forge so that I can't imitate them and feel confused. Now I downgrade my forge to use the same APIs of these mods. So, how can I do? If the stable version will be as same as the recent ones. MUST I LEARN THE NEW API INSTEAD OF OLD ONE?
