VSCODE搭建JAVA基本开发环境，vscode搭建java

1.安装java extension

• Language Support for Java™ by Red Hat
• Debugger for Java
• Java Test Runner
• Maven for Java

2.下载JDK并在系统变量配置JAVA_HOME路径。
3.打开VSCODE个人设置界面，配置java.home路径。

4.新建项目建立.classpath、.project、.launch.json文件，具体如下。
.classpath：

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
	<classpathentry kind="src" path="src"/>
	<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8/"/>
	<classpathentry kind="con" path="org.eclipse.buildship.core.gradleclasspathcontainer"/>
	<classpathentry kind="output" path="bin"/>
	<!-- <classpathentry kind="lib" path="lib/fel-0.8.jar"/>引用的jar包 -->
</classpath>

.project:

<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
	<name>testjava</name>
	<comment>Project testjava created by Buildship.</comment>
	<projects>
	</projects>
	<buildSpec>
		<buildCommand>
			<name>org.eclipse.jdt.core.javabuilder</name>
			<arguments>
			</arguments>
		</buildCommand>
		<buildCommand>
			<name>org.eclipse.buildship.core.gradleprojectbuilder</name>
			<arguments>
			</arguments>
		</buildCommand>
	</buildSpec>
	<natures>
		<nature>org.eclipse.jdt.core.javanature</nature>
		<nature>org.eclipse.buildship.core.gradleprojectnature</nature>
	</natures>
</projectDescription>

.launch.json:

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "java",
      "name": "Debug (Launch)",
      "request": "launch",
      "cwd": "${workspaceFolder}/bin",
      "sourcePaths": [
        "$(workspaceRoot)/src"
      ],
      "classPaths": [
        "",
        "$(workspaceRoot)/bin"
      ],
      // "mainClass": "Main",入口类名
      "args": ""
    }
  ]
}

5.好了，现在让我们搞个类跑一下hello world!
Main.java:

public class Main{
  public static void main(String[] args) {
      System.out.println("hello world!"); 
  }
}
