如何解决VScode UnsupportedClassVersionError? [英] How to solve VScode UnsupportedClassVersionError?

问题描述

当我运行HelloWorld时，它将返回:

When i run my HelloWorld, it returns:

"java.lang.UnsupportedClassVersionError:HelloWorld已编译通过Java Runtime的最新版本(类文件版本)52.65535)，此版本的Java运行时只能识别52.0以下的类文件版本.

"java.lang.UnsupportedClassVersionError: HelloWorld has been compiled by a more recent version of the Java Runtime (class file version 52.65535), this version of the Java Runtime only recognizes class file versions up to 52.0 "

我该如何解决这个问题?

How do I solve this problem?

public class HelloWorld{
    public static void main(String[] args) {
        System.out.println("123");
    }
}

问题与Java Debugger扩展有关.我遇到了同样的问题，它已经记录在问题日志中: https://github.com/Microsoft/vscode-java-debug/issues/555

问题仅适用于单个文件应用程序，例如HelloWorld.如果您运行的是Maven项目，那没关系.

Problem is only with single file applications like HelloWorld. It is ok if you run maven project.
