多模块项目。包括：主模块和子模块：客户端，共享服务器。如何？ [英] Multi module project. Consist of : parent module and submodules: client, shared, server. How to?

问题描述

我想有web应用程序的多模块项目。有父模块的内容3子模块：

I would like to have multimodule project of web app. There is parent module that content 3 submodules:

客户端，共享，服务器。

我想建立一个与Maven。

I would like to build that with maven.

我想客户端可以访问：服务器和共享模块code。

I would like to client could access: server and shared modules code.

我想共享可以访问：服务器模块code

I would like to shared could access: server modules code.

依赖我wonna实现

client -> shared -> server
client -> server

难道是用Maven构建？

Can it be build with maven?

下面是我目前的劲歌：

父：

<modules>
    <module>server</module>
    <module>shared</module>
    <module>client</module>
</modules>

客户端：

<dependencies>
    <dependency>
        <groupId>pl.derp</groupId>
        <artifactId>shared</artifactId>
        <version>${project.version}</version>
    </dependency>
    <dependency>
        <groupId>pl.derp</groupId>
        <artifactId>server</artifactId>
        <version>${project.version}</version>
    </dependency>
</dependencies>

共享不依赖

服务器：

<dependencies>
    <dependency>
        <groupId>pl.derp</groupId>
        <artifactId>shared</artifactId>
        <version>${project.version}</version>
    </dependency>
</dependencies>

修改

我想有我的共享模块能够获得服务器模块code，但是当我添加依赖关系服务器模块共享模块内，我收到关于循环依赖一个错误，并且不能建立项目。我的问题是如何prepare劲歌所有子模块实现这一目标？正如你可以看到共享模块没有任何相关性了。 -

I would like to have my shared module had access to server module code, but when I add dependencies to server module inside shared module, I am getting an error about cycle dependencies and can not build project. My question is how to prepare poms in all submodules to achieve this? As You can see shared module doesn't have any dependencies now. –

推荐答案

我倾向于尝试，使生活更简单，只是有两个模块（模式，代理服务器和客户端code）。

I'd tend to try and make life simpler and just have two modules (for model, proxies and client code).

例如

model (maven project)
webclient (maven project)
    shared (package)
    server (package)
    client (package)

我不完全相信你一定能因为交叉依赖三个模块做到这一点。

I'm not totally sure you can do it with three modules because of the cross dependencies.

FWIW我们有数据库，模型和客户端（GWT Web客户端）作为分割的主要关切，并保持相关性松潘县的模块。

FWIW we have modules for database, model and client (gwt web client) as that splits the main concerns and keeps the dependencies sane.
