使用分类器更改对工件的Maven依赖关系 [英] Change maven dependency for artifact using classifier

问题描述

使用Maven jar插件，我构建了两个jar:bar-1.0.0.jar和bar-1.0.0-client.jar.

With the maven jar plugin I build two jar: bar-1.0.0.jar and bar-1.0.0-client.jar.

实际上，在我的POM中，我具有以下依赖性:

Actually in my POM I have the following dependency:

<dependency>   
   <groupId>de.app.test</groupId>
   <artifactId>foo</artifactId>
   <version>1.0.0</version>
</dependency>

此工件还存在于两个版本的bar-1.0.0.jar和bar-1.0.0-client.jar

This artifact exist also in two version bar-1.0.0.jar and bar-1.0.0-client.jar

我想使bar-1.0.0-client.jar依赖于foo-1.0.0-client.jar和bar-1.0.0.jar依赖于foo-1.0.0.jar .

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

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

->第一个(错误的)解决方案:定义所提供的范围，并在使用bar.jar时使用正确的foo包

->First (wrong) solution: define the scope as provided and use the right foo package when using bar.jar

->第二(长)解决方案:将服务器"分类器添加到另一个jar中.使用不同的配置文件来构建foo工件，并将分类器放在属性中.

->Second (long) solution : Add 'server' classifier to the other jar. Use different profile to build the foo artifact and put the classifier in a property.

<dependency>
    <groupId>de.app.test</groupId>
    <artifactId>foo</artifactId>
    <version>1.0.0</version>
    <classifier>${profile.classifier}<classifier>
</dependency>

================
关于配置文件解决方案.

================
Concerning the profile solution.

此解决方案的问题是由于我的客户端接口缺少一些接口，并且在编译阶段maven抛出了编译错误.

The problem with this solution is due to the fact that my client interface have some missing interfaces and maven throw a compilation error during the compile phase.

如果我使用myapp-model和其他项目，那么我就不会依赖于正确的myapp-interface.

And if I use myapp-model and an other project I didn't not have dependency to the right myapp-interface.

我想知道是否有可能建造一个罐子并将特定的pom放入其中?

I wonder if it's possible to build a jar and put a specific pom inside ?

推荐答案

用于接口.

我什么也没做，并构建了两个interfaces.jar(客户端+服务器).

I change nothing and build the both interfaces.jar (client + server).

对于模型 我将两个jar都导入为可选

For the Model I import the both jar as optional

<dependency>
        <groupId>com.app</groupId>
        <artifactId>myapp-interfaces</artifactId>
        <version>${myapp-interfaces.version}</version>
        <classifier>client</classifier>
        <optional>true</optional>
    </dependency>
    <dependency>
        <groupId>com.app</groupId>
        <artifactId>myapp-interfaces</artifactId>
        <version>${myapp-interfaces.version}</version>
        <classifier>server</classifier>
        <optional>true</optional>
    </dependency>

这样我就可以构建两个模型的版本而没有任何错误.

With that I can build the both model's version without any error.

在我的客户端应用程序和服务器应用程序中

对于每个应用程序，我都创建了对正确的interfaces.jar和models.jar的依赖项

For each application I create the dependency to the right interfaces.jar and models.jar
