Context
-------
I have an IntelliJ project with multiple modules. I am using the maven-shade-plugin to jar with dependencies whilst reducing jar size. The project structure is as follows;
- top-level parent (pom) (aggregates api and world-teleport)
- api (inherits parent)
- world-teleport (inherits parent, api)

The problem

Everytime I perform a clean and a new install or package it is indicated to me that there are duplicate dependencies.

Question

What is causing this warning? What if anything is wrong with my maven pom structure?

Duplicate Question

If this is a duplicate question please feel free to provide any resources, they would be greatly appreciated.

答案1

得分: 1

以下是翻译好的内容：

我认为问题在于您在api模块和module-1模块中都添加了io.github.classgraph和org.spigotmc的依赖。

问题的发生过程如下：

  1. api模块将生成包含io.github.classgraph和org.spigotmc依赖的jar构件。
  2. 依赖于api模块的module-1模块将导入该jar文件。
  3. 现在，module-1模块从jar中获取了io.github.classgraph和org.spigotmc的依赖，并且在module-1模块的pom.xml文件中再次声明了它们。

因此，解决方案是从module-1模块的pom.xml中移除io.github.classgraph和org.spigotmc的依赖：

<parent>
    <groupId>com.jsonmack</groupId>
    <artifactId>mcplugins</artifactId>
    <version>1.10-SNAPSHOT</version>
</parent>

<dependencies>
    <dependency>
        <groupId>com.jsonmack</groupId>
        <artifactId>api</artifactId>
        <version>1.10-SNAPSHOT</version>
    </dependency>

    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
    </dependency>
</dependencies>
英文:

I think the problem is that you have the io.github.classgraph and the org.spigotmc dependency added in the api and the module-1 as well.

So what happens:

  1. The api module will generate the jar artifact with
    io.github.classgraphand the org.spigotmc dependencies included in it.
  2. The module-1 modul which depends on the api module will import the
    jar file.
  3. Now the module-1 module has the io.github.classgraphand the org.spigotmc dependency
    from the jar, and they are declared again in the module-1 module's
    pom.xml file.

So the solution will be to remove the io.github.classgraph and the org.spigotmc dependency from your module-1 module pom.xml:

&lt;parent&gt;
&lt;groupId&gt;com.jsonmack&lt;/groupId&gt;
&lt;artifactId&gt;mcplugins&lt;/artifactId&gt;
&lt;version&gt;1.10-SNAPSHOT&lt;/version&gt;
&lt;/parent&gt;
&lt;dependencies&gt;
&lt;dependency&gt;
&lt;groupId&gt;com.jsonmack&lt;/groupId&gt;
&lt;artifactId&gt;api&lt;/artifactId&gt;
&lt;version&gt;1.10-SNAPSHOT&lt;/version&gt;
&lt;/dependency&gt;
&lt;dependency&gt;
&lt;groupId&gt;junit&lt;/groupId&gt;
&lt;artifactId&gt;junit&lt;/artifactId&gt;
&lt;/dependency&gt;
&lt;/dependencies&gt;

在这里，我想要赞赏您积极的态度，注意到许多开发人员不断添加不必要的依赖项，对于这些警告他们并不在意。

回答我的问题，因为您有三个不同的模块。这些模块会被单独部署（独立地），还是会一起打包在一个war、jar或者包中？

如果您的答案是肯定的，那就没什么可担心的了。

如果您的答案是否定的，那么我认为io.github的依赖是多余的，可以将其去除。

从子模块或者引用模块中删除这些多余的依赖项。

抱歉如果有拼写错误，我是在手机上回答的，但会为您完成这项工作。

英文:

Well here I would like to appreciate your proactive was of noticing that as many developers keep on adding decencies and do not bother about such warnings.

Answer my question, as you have three different modules. Will those modules be deployed differently (independently) or together in one war or jar or package?

If your answer is yes here is nothing to worry.

If your answer is no then
I see io.github dependency as redundant just get rid of it.

Delete the redundant dependencies from child module or referenced module.

Sorry if there are typos, answered in mobile but will do the job for you.

谢谢大家的帮助。我已经找到了解决方案，即 API 模块应该继承来自父模块的依赖项，如 spigot 和 classgraph，但这些依赖项的范围应该仅为 provided。这将允许依赖项在编译时被引入，但在打包时被排除在 shading 之外。这是可能的，因为 API 模块将不会在这些模块之外被使用，所以 API 模块始终会通过其他模块来获取所需的依赖项。

api-module.pom

    <dependencies>
        <dependency>
            <groupId>io.github.classgraph</groupId>
            <artifactId>classgraph</artifactId>
            <scope>provided</scope>
        </dependency>

        <dependency>
            <groupId>org.spigotmc</groupId>
            <artifactId>spigot-api</artifactId>
            <scope>provided</scope>
        </dependency>

        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>
英文:

Thank you for the help everyone. I have found the solution which is that the API module should inherit the dependencies such as spigot and classgraph from parent but the scope of those dependencies should only be provided. This will allow the dependencies to compile but be excluded from packaging when shading. This is possible because API will not be used outside of these modules, so the API will always have the dependencies required through the other modules.

api-module.pom

    &lt;dependencies&gt;
        &lt;dependency&gt;
            &lt;groupId&gt;io.github.classgraph&lt;/groupId&gt;
            &lt;artifactId&gt;classgraph&lt;/artifactId&gt;
            &lt;scope&gt;provided&lt;/scope&gt;
        &lt;/dependency&gt;

        &lt;dependency&gt;
            &lt;groupId&gt;org.spigotmc&lt;/groupId&gt;
            &lt;artifactId&gt;spigot-api&lt;/artifactId&gt;
            &lt;scope&gt;provided&lt;/scope&gt;
        &lt;/dependency&gt;

        &lt;dependency&gt;
            &lt;groupId&gt;junit&lt;/groupId&gt;
            &lt;artifactId&gt;junit&lt;/artifactId&gt;
            &lt;scope&gt;test&lt;/scope&gt;
        &lt;/dependency&gt;
    &lt;/dependencies&gt;
