dependencies节点要放到project下，即所有节点都必须放到project中，参考如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>org.example</groupId>
    <artifactId>com.lyc</artifactId>
    <packaging>jar</packaging>
    <version>1.0-SNAPSHOT</version>

    <dependencies>

    <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
             <version>4.12</version>
             <scope>test</scope>
    </dependency>

      </dependencies>
</project>
