当我尝试使用 vscode 调试 java 程序时收到此错误：

java.lang.UnsupportedClassVersionError: 
test (class file version 52.65535) was compiled with preview features that are unsupported. 
This version of the Java Runtime only recognizes preview features for class file version 55.65535

这是launch.json：

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "java",
            "name": "Debug (Launch) - Current File",
            "request": "launch",
            "mainClass": "${file}"
        },
        {
            "type": "java",
            "name": "Debug (Launch)-test",
            "request": "launch",
            "mainClass": "test"
        }
    ]
}

这是java的版本：

java --version:
openjdk 11.0.2 2019-01-15
OpenJDK Runtime Environment (build 11.0.2+9-Ubuntu-3ubuntu118.04.2)
