事情是这样的：
我在VsCode上写了一段代码（Java）
之前还挺正常的，直到今天我打开Vs的时候
它给我报错Error occured initializing language server
.log的日志报错是这样的：

}
（代码块里没有纯文本选项QAQ，所以只能用xml）
我当时安装了以下几个插件：
Extension Pack for Java
Maven for Java
Debugger for Java
Project Manager for Java
Test Runner for Java
Language Support for Java(TM) by Red Hat
Java Run
用Java Run运行是可以运行的，
但是如果alt+F5的话，调试终端会报错：
Exception in thread "main" java.lang.Error: Unresolved compilation problems: ocumentation.ErrorMappingsDocGenerator'
MysqlErrorNumbers cannot be resolved
MysqlErrorNumbers cannot be resolved to a type
MysqlErrorNumbers cannot be resolved
at documentation.ErrorMappingsDocGenerator.dumpSqlStatesMappingsAsXml(ErrorMappingsDocGenerator.java:56) r.java:56)
at documentation.ErrorMappingsDocGenerator.main(ErrorMappingsDocGenerator.java:44)
调试命令是：c:; cd 'c:\Users\Administrator\Desktop\Javatest'; & 'C:\Program Files\Java\jdk-18.0.1.1\bin\java.exe' '--enable-preview' '-XX:+ShowCodeDetailsInExceptionMessages'
'-cp' 'C:\Users\Administrator\AppData\Roaming\Code\User\workspaceStorage\b8aed93921873591fa0a8b328e92a733\redhat.java\jdt_ws\jdt.ls-java-project\bin' 'documentation.ErrorMappingsDocGenerator'
而且我写的代码里根本没有用到MySQL模块
C:\Users\Administrator\AppData\Roaming\Code\User\workspaceStorage\b8aed93921873591fa0a8b328e92a733\redhat.java\jdt_ws\jdt.ls-java-project\bin路径下有一个documentation文件夹，里面有一个ErrorMappingsDocGenerator.class，反编译之后是这样的：
package documentation;
public class ErrorMappingsDocGenerator {
public ErrorMappingsDocGenerator() {
}
public static void main(String[] args) throws Exception {
dumpSqlStatesMappingsAsXml();
}
public static void dumpSqlStatesMappingsAsXml() throws Exception {
throw new Error("Unresolved compilation problems: \n\tMysqlErrorNumbers cannot be resolved\n\tMysqlErrorNumbers cannot be resolved to a type\n\tMysqlErrorNumbers cannot be resolved\n");
}
}
我试过把eclipse和vscode都卸载有重新安装了，可是丝毫没有效果。
求各位博主，到底该怎么办
