idea,eclipse创建多模块项目

Posted 2020-09-26 牵牛花

新建一个maven项目

iead,新建是不选择archetype,新建好之后,pom中的

<packaging>pom</packaging>节点是默认的,如果不是要改成这这样子

然后选中这个项目,新建一个module,之后就和建立普通项目一样了.

 

eclipse,新建一个maven项目,archetype 选quickstart那个,本来应该是不选的,但是好像不能不选

然后修改<packaging>pom</packaging>,然后选中项目点击新增此时选择maven model 

然后想建立普通项目一样就建立好了

<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>

        </dependency>

        <dependency>

        <dependency>

            <artifactId>hadoop-mapreduce-client-common</artifactId>

    </dependencies>
</project>

这个是ieda子项目的pom,上部有些和eclipse生成的不一样,需要改成这样子的
