[解決済み] Minecraft Forge Mod Loader (FML) ロードしてクラッシュするMC

質問内容

Minecraft CodingとForgeの初心者です。FML(Forge Mod Loader)の読み込みでエラーが発生するというエラーが何度も出ます。FMLは1.12.2 MC用、Forgeバージョンは1.12.2-14.23.5.2854を所持しています。 Forge バージョン 1.12.2-14.23.5.2855 も試しましたが、同じエラーが発生しました。 私はJRE 1.8.0_251を使用しています。 私のIDEはEclipse 2020-12です。

そして、Minecraft Client 1.12.2 を起動する "runClient.launch" を実行すると、Constructing Mods と表示されるが、3ステップ目まで来ると、バーンとクラッシュしてしまうのだ。 eclipseの環境設定タブで、「正しいJRE」を選択しています。 Plsは、この問題に関して私を助けてください。

解決方法は？

1.12.2より上位のバージョンにアップグレードすることで解決しました。これで、EclipseからrunClientが実行されるようになりました。 ありがとうございます。
