在vscode中运行java代码时出现的问题

我想我已经把

task.json

和

launch.json

设置正确了

tasks.json

{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
    {
        "taskName": "Compile Java",
        "type": "shell",
        "command": "javac ${file}",
        "group": {
            "kind": "build",
            "isDefault": true
        }
    }
]
}

{

"version": "0.2.0",
"configurations": [
    {
        "name": "Java",
        "type": "java",
        "request": "launch",
        "stopOnEntry": true,
        "externalConsole": false,
        "preLaunchTask": "Compile Java",
        "jdkPath": "${env:JAVA_HOME}/bin",
        "cwd": "${fileDirname}",
        "startupClass": "${fileBasenameNoExtension}",
        "classpath": [
            "/Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home/lib",
            ".",
            "${fileDirname}"
        ]
    },
    {
        "name": "Java Console App",
        "type": "java",
        "request": "launch",
        "stopOnEntry": true,
        "preLaunchTask": "Compile Java",
        "jdkPath": "${env:JAVA_HOME}/bin",
        "cwd": "${fileDirname}",
        "startupClass": "${fileBasenameNoExtension}",
        "classpath": [
            "/Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home/lib",                
            ".",
            "${fileDirname}"
        ],
        "externalConsole": true
    }
]
}

这里是

launch.json

"version": "2.0.0",
"tasks": [
    {

        "group": {
            "kind": "build",
            "isDefault": true
        }
    }
]
}

        "classpath": [

            "${fileDirname}"
        ]
    },
    {
        "name": "Java Console App",
        "type": "java",
        "request": "launch",
        "stopOnEntry": true,
        "preLaunchTask": "Compile Java",

            "${fileDirname}"
        ],
        "externalConsole": true
    }
]
}

但是，当我单击调试按钮时，没有发生任何事情，调试控制台中也没有任何内容：

我点击顶部的暂停按钮，但什么也没发生。 然后我设置了一个断点，但它看起来像是试图进入程序，如下所示：
