我一直在尝试使用MCP将Minecraft源代码反编译为Eclipse工作区。我正在使用mcp940反编译Minecraft 1.12。当我运行BATCH文件decompile.bat时，它给了我很多错误。我正在跟踪此问题底部的视频教程，主持人完全跳过了这一步。 eclipse工作区仍在加载并具有所有代码，但是所说的代码充满错误。当我尝试运行带有主方法的类Start时，出现以下错误消息：
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
该视频教程链接到另一个视频教程（也在下面链接），有关修复领域jar版本。我已解决此问题，但似乎该问题只是其中的一个。 修复此部分后，我尝试运行它，但仍然收到相同的错误消息。
这是控制台的输出：

Press any key to continue . . .
注意：我不得不删除一堆折旧警告以适合此要求。
这应该只是在调试模式下实时运行Minecraft。

答案 0 :(得分：2)
我发现了问题，并将其放置在这里，供任何分享我的问题的人使用。我使用的是JDK 10，这导致了很多版本错误。我下载了JDK和JRE 8，调整了系统变量以解决该问题，删除了失败的MCP eclipse工作区，重新下载了MCP，这次再次与Java 8一起运行decompile.bat。
这是我使用的Java 8版本的下载链接： https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
