环境变量配置

   MAVEN_HOME      E:\IDEA\apache-maven-3.9.0

  path 增加 %MAVEN_HOME%\bin

 

E:\IDEA\apache-maven-3.9.0\conf\settings.xml  要修改的地方

 <localRepository>E:\IDEA\maven-repository</localRepository>

  单个项目pom.xml

<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>wtl.test</groupId>
  <artifactId>wtl</artifactId>
<!--  生成的包,有jar \ war, war用于web-->
  <packaging>war</packaging>
  <version>1.0-SNAPSHOT</version>

<!--  模块名称,多模块引用有用到-->
  <name>wtl Maven Webapp</name>

  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
<!--      compile	编译时需要用到该jar包(默认) -->
<!--      test	编译Test时需要用到该jar包	 -->
<!--      runtime	编译时不需要,但运行时需要用到 -->
<!--      provided	编译时需要用到,但运行时由JDK或某个服务器提供-->
      <scope>test</scope>
    </dependency>
  </dependencies>
  <build>
<!--    要填一个默认-->
    <defaultGoal>compile</defaultGoal>
<!--    编译后打包文件名,如这个会是wtl.war-->
    <finalName>wtl</finalName>

<!--    使用的编译插件-->
    <plugins>

      </plugin>
    </plugins>

  </build>
  <properties>
<!--    编译的编码,中文要用UTF-8,这个是用于编译后的*.class里的文件的中文,不是浏览器请求说的那个中文-->
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

===========================================================

多模块

模块的就可以简化为

<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>

    <parent>
        <groupId>com.itranswarp.learnjava</groupId>
        <artifactId>parent</artifactId>
        <version>1.0</version>
        <relativePath>../parent/pom.xml</relativePath>
    </parent>

    <artifactId>module-a</artifactId>
    <packaging>jar</packaging>
    <name>module-a</name>
</project>

  模块B依赖A这样写

 <dependencies>
        <dependency>
            <groupId>com.itranswarp.learnjava</groupId>
            <artifactId>module-b</artifactId>
            <version>1.0</version>
        </dependency>
    </dependencies>

  

 

根级别的pom.xml

<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.itranswarp.learnjava</groupId>
    <artifactId>build</artifactId>
    <version>1.0</version>
    <packaging>pom</packaging>
    <name>build</name>

    <modules>
        <module>parent</module>
        <module>module-a</module>
        <module>module-b</module>
        <module>module-c</module>
    </modules>
</project>

  

 

 servlet5.0的依赖
<dependency>
            <groupId>jakarta.servlet</groupId>
            <artifactId>jakarta.servlet-api</artifactId>
            <version>5.0.0</version>
            <scope>provided</scope>
</dependency>
