Question

我正在使用一个自定义Maven 3打包插件来处理一些非java工件，并且在传递依赖性的过程中遇到问题。我已经定义了三个项目， model ， model-impl 和 cli ，其依赖关系如下：

cli
  model-impl
    model

我的自定义生命周期插件正在每个项目中调用，我可以成功构建模型和 model-impl 。对于每个项目，预期的工件都存储在我的本地存储库中。然而， cli 失败了，因为我没有将 model 作为我的Mojo中的依赖项。我不完全确定这是我的代码中的问题，因为即使使用 mvn依赖：dependency-tree 也不会显示完整的依赖关系层次结构：

[INFO] Scanning for projects...

[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------

在这里，我希望每个项目都能看到一个包含三个级别的树。

这是我的自定义插件中定义的components.xml：

<component-set>
    <components>
        <component>
            <role>org.apache.maven.lifecycle.mapping.LifecycleMapping</role>

                    <deploy>org.apache.maven.plugins:maven-deploy-plugin:deploy</deploy>
                </phases>
            </configuration>
        </component>
        <component>
            <role>org.apache.maven.artifact.handler.ArtifactHandler</role>
            <role-hint>myproj</role-hint>

            <configuration>

                <addedToClasspath>true</addedToClasspath>
                <includesDependencies>true</includesDependencies>
            </configuration>
        </component>
    </components>
</component-set>

所有项目POM的包装都设置为 myproj ，并且所有依赖项的类型都设置为 myproj 。这是 cli 项目的pom：

<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">

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

        <dependency>

            <artifactId>myproj-model-impl</artifactId>
            <version>1.0.0-SNAPSHOT</version>
            <type>myproj</type>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>com.corp.maven</groupId>
                <artifactId>myproj-plugin</artifactId>
                <version>1.0.0-SNAPSHOT</version>
                <extensions>true</extensions>
            </plugin>
        </plugins>
    </build>
</project>

impl 项目的POM看起来很相似。任何想法都是我错过的？

includesDependencies

Answer 2

在尝试通过maven将我的android lib包含到我的另一个项目时，我一直在努力解决类似的问题。我的研究表明，库的pom文件不包含在maven库中，对于像我这样的一些案例 - 我有一个.aar文件。因此，您的项目构建系统对这些传递依赖项一无所知。我的解决方案是手动将它们指向我的Gradle文件。您可以在this topic中更具体地熟悉这一点。

自定义Maven包装，传递依赖性不包括在内
