在Maven项目的模块内共享类 [英] Share classes within modules in maven project

问题描述

首先，我是maven的新手，对于这个问题是否太简单，我们深感抱歉:)

firstly I'm new to maven , so sorry for the question if it's too simple :)

我有主模块"main" 和子模块:a，b，c，...

I have main module "main" and child modules : a , b , c , ...

我想要与子模块b共享子模块a中的一些数据.

What I want is to share some data which is in child module a , with child module b.

父pom看起来像: 4.0.0

The parent pom looks like : 4.0.0

    <groupId>Parent</groupId>
    <artifactId>Parent</artifactId>
    <packaging>pom</packaging>
    <version>1.0-SNAPSHOT</version>

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

我要分享的孩子看起来像:

The child I want to share looks like :

<parent>
    <artifactId>Parent</artifactId>
    <groupId>Parent</groupId>
    <version>1.0-SNAPSHOT</version>
</parent>

<modelVersion>4.0.0</modelVersion>
<artifactId>a</artifactId>
</project>

和消费者"孩子看起来像:

and "consumer" child looks like :

<parent>
        <artifactId>Parent</artifactId>
        <groupId>Parent</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>

    <modelVersion>4.0.0</modelVersion>
    <artifactId>b</artifactId>

    <dependencies>
        <dependency>
            <groupId>${project.groupId}</groupId>
            <artifactId>a</artifactId>
            <version>${project.version}</version>
            <type>jar</type>
            <scope>compile</scope>
        </dependency>
    </dependencies>

我确实看到jar文件已添加到外部库"中(我正在使用Intellij) 但是该jar仅包含META-INF文件夹，没有代码(可以吗?)

I do see the jar file being added to the "External Library" (I'm using Intellij) But the jar contains only META-INF folder without the code (is it ok ?)

故事的结尾，我不能在ChildB类中使用ChildA类... 任何需要帮助的人！！

End of story, I cannot use Class ChildA in ChildB classes ... Any help whould be appriciated !!

推荐答案

问题是我已经弄乱了" maven的项目结构.... 一旦构建了应由maven进行的模块，就可以像一个魅力一样工作了:) http://maven.apache.org/guides /introduction/introduction-to-the-standard-directory-layout.html

The problem was that I've "btoken" maven's project stracture .... Once I've build the module as it should be by maven , works like a charm :) http://maven.apache.org/guides/introduction/introduction-to-the-standard-directory-layout.html
