自定义Maven包装,传递依赖性不包括在内

Question

我正在使用一个自定义的Maven 3打包插件来处理一些非java工件,并且遇到了一个让传递依赖性工作的问题.我有三个项目定义,模型,模型impl和cli,依赖如下:

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模型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,因为我没有将模型作为我的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依赖项:dependency-tree也不会显示完整的依赖关系层次结构:

[INFO] Scanning for projects...

在这里,我希望每个项目都能看到一个有三个级别的树.

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>
            <role-hint>myproj</role-hint>
            <implementation>
                org.apache.maven.lifecycle.mapping.DefaultLifecycleMapping
            </implementation>
            <configuration>
                <phases>
                    <initialize>com.corp.maven:myproj-plugin:unpackageDependencies</initialize>
                    <process-resources>org.apache.maven.plugins:maven-resources-plugin:resources</process-resources>
                    <compile>com.corp.maven:myproj-plugin:compile</compile>
                    <process-test-resources>org.apache.maven.plugins:maven-resources-plugin:testResources</process-test-resources>
                    <test-compile>org.apache.maven.plugins:maven-compiler-plugin:testCompile</test-compile>
                    <test>org.apache.maven.plugins:maven-surefire-plugin:test</test>
                    <package>com.corp.maven:myproj-plugin:package</package>
                    <install>org.apache.maven.plugins:maven-install-plugin:install</install>
                    <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>
            <implementation>org.apache.maven.artifact.handler.DefaultArtifactHandler</implementation>
            <configuration>
                <type>myproj</type>
                <extension>myproj</extension>
                <packaging>myproj</packaging>
                <addedToClasspath>true</addedToClasspath>
                <includesDependencies>true</includesDependencies>
            </configuration>
        </component>
    </components>
</component-set>

所有项目POM都将其包装设置为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">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.corp.arthur.nodes</groupId>
    <artifactId>myproj-cli</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>myproj</packaging>

    <name>myproj Test</name>

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

    <dependencies>
        <dependency>
            <groupId>com.corp.arthur</groupId>
            <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.任何想法都是我缺少的？

通过追踪该类的源代码，终于弄清楚发生了什么DefaultDependencyCollector。事实证明，我需要includesDependencies在我的 Components.xml 中将其设置为false。发生的情况是依赖项收集器看到该标志为 true，这意味着依赖项包含在工件中，因此不会递归它们。将其设置为 false 后，它会递归，并且我得到了预期的行为。
