maven继承父工程统一版本号

一、建立一个maven工程 pom类型

　　统一管理依赖以及版本号

　　子工程不会使用所有的定义的依赖

　　子工程使用依赖时无需指定版本号

其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/xsd/maven-4.0.0.xsd">

  <packaging>pom</packaging>
  <!-- 集中定义依赖版本号 -->

二、新创建一个maven工程

在pom.xml中，继承父工程，依赖去掉版本号

<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">

            <artifactId>poi</artifactId>
            <version>3.10.1</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind -->
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>

        <!-- 切面 -->

        </dependency>
        <!-- pagehelper -->

            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper</artifactId>
            <version>5.1.2</version>
        </dependency>

        <!-- c3p0数据源 -->
        <dependency>

        </dependency>

        <!-- -->
        <dependency>

            <artifactId>slf4j-log4j12</artifactId>
        </dependency>
        <!-- https://mvnrepository.com/artifact/junit/junit -->

        <dependency>
            <groupId>commons-fileupload</groupId>
            <artifactId>commons-fileupload</artifactId>
            <version>1.3.1</version>
        </dependency>


        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-core</artifactId>
            <version>1.4.0</version>
        </dependency>
        <dependency>

            <version>1.4.0</version>
        </dependency>
  </dependencies>
</project>

 三、配置tomcat插件

在子工程pom.xml中继续添加

<build>
      <plugins>
          <!-- 配置tomcat插件 -->
          <plugin>
              <groupId>org.apache.tomcat.maven</groupId>
            <artifactId>tomcat7-maven-plugin</artifactId>
            <!-- tomcat配置 -->
            <configuration>
                <!-- 端口号 -->
                <port>8001</port>
                <!-- 项目的路径 -->
                <path>/</path>
            </configuration>
          </plugin>
      </plugins>
  </build>

子工程邮件run as configurations ，点击左边的Maven Build新增配置

 

 运行后，会发生以下错误

 这时将父工程maven install，安装到本地仓库中，再运行则不报错
