Minecraft Forge Mod Loader (FML) 加载和崩溃 MC

Question

我是 Minecraft Coding and Forge 的新手。 我反复收到 FML（Forge Mod Loader）加载导致错误的错误。 我有 1.12.2 MC 和 Forge 版本 1.12.2-14.23.5.2854 的 FML 我也尝试了 Forge 版本 1.12.2-14.23.5.2855，但抛出了同样的错误。 我正在使用 JRE 1.8.0_251。 我的 IDE 是 Eclipse 2020-12

当我执行启动 Minecraft Client 1.12.2 的“runClient.launch”时，它会显示 Constructing Mods，但是当涉及到第 3 步时，然后 bam，它在 eclipse 的首选项选项卡中崩溃。我选择了正确的 JRE。 请帮我解决这个问题。

JVM 参数-Xmx2G

Answer 1

我只是想弄清楚如何解决这个问题。 根据我的研究，您可以删除主目录中的.gradle文件夹，或者重新加载 gradle。

Answer 2

当我执行“runClient”时，我也遇到了与您相同的错误（唯一的区别是我使用的是 IDEA）。 我发现目录名可能是错误的原因。我的目录名是“1.12.2”。我尝试将其更改为“mod”并rebuild.gradle。 之后“runClient”就可以正常运行了。
