導入Idea

源碼下載下來之后，新建一個tomcat文件夾，把源碼文件夾復制進去重命名為apache-tomcat，
在tomcat文件夾下建立一個pom.xml


<?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/maven-v4_0_0.xsd">

    <modelVersion>4.0.0</modelVersion>
    <groupId>com.ztianzeng</groupId>
    <artifactId>tomcat</artifactId>
    <name>Tomcat</name>
    <version>1.0</version>
    <packaging>pom</packaging>

    <modules>
        <module>apache-tomcat-8.5.16-src</module>
    </modules>
</project>

在源碼包里面也建立一個pom.xml


<?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"

                </configuration>
            </plugin>
        </plugins>
    </build>
    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>

            <scope>test</scope>

最后的目錄結構應該是這樣子：
