标题Gradle构建问题
切换到Project工程下.idea/gradle.xml添加属性
<option name="delegatedBuild" value="false" />
图例
PS：下面通过示例代码看下JAVA中的main函数
package com.han;
public class HanTest {
public static void main(String[] args){
if(args==null){
throw new NullPointerException("The input is \"null\"");
}else if((args.length!=1&&args.length!=2)){
Throwable cause=new Throwable("You have to input 1 or 2 String arguments");
throw new IllegalArgumentException("Wrong numbers of args",cause);
//throw new IllegalArgumentException("Wrong numbers of args");
}else if(args.length==1){
System.out.println(args[0]);
}else if(args.length==2){
System.out.println(args[0]);
System.out.println(args[1]);
}
}
}
package com.han;
public class HanTest2 {
public static void main(String[] args){
String[] input={"han"};
//HanTest.main(null);
HanTest.main(input);
}
}
