执行 Minecraft mod 时线程“主”java.lang.ExceptionInInitializerError 中的错误异常

Question

所以，我正在关注 1.16 中的 Minecraft 改装教程，我使用 Eclipse 和 1.16.4 mdk，一切都很顺利，直到我尝试启动游戏，它一直出现错误，这是控制台：

我尝试使用 ChatGPT 来修复它，但它说这是一个 Java 兼容性问题，我检查了几次后不是，版本是正确的，JRE 1.8.

Answer 1

java.lang.reflect.InaccessibleObjectException: Unable to make field private final java.util.jar.JarVerifier java.util.jar.Manifest.jv accessible: module java.base does not "opens java.util.jar" to unnamed module @5f683daf

版本对，JRE 1.8.

你的那一行错误意味着你实际上没有使用 JRE 1.8。模块和开放在当时甚至不作为概念存在。如果您真的切换到 JRE 1.8，那么该错误就会消失。
