karaf-maven-plugin：将依赖项定义为特性

Question

我正在尝试让 karaf-maven-plugin 为我的应用程序生成一个功能文件。该应用程序依赖于 cxf 功能，但我似乎无法让插件生成功能 xml 来反映这一点。

我的功能模块截图：

    <dependencies>
        <dependency>
            <groupId>com.test.test</groupId>
            <artifactId>test</artifactId>
        </dependency>
    </dependencies>

    <build>
        <pluginManagement>
            <plugins>
                <plugin>
                    <groupId>org.apache.karaf.tooling</groupId>

                    <version>3.0.3</version>
                    <extensions>true</extensions>

            <startLevel>80</startLevel>
        <includeTransitiveDependency>true</includeTransitiveDependency>
        <aggregateFeatures>false</aggregateFeatures>
          </configuration>
        </plugin>
        </plugins>
    </build>

                <classifier>features</classifier>
                <type>xml</type>
            </dependency>


            <dependency>
                <groupId>org.apache.commons</groupId>
                <artifactId>commons-lang3</artifactId>
                <version>3.3.2</version>
            </dependency>
        </dependencies>

如您所见，我尝试将功能工件定义为编译范围的依赖项，以及 commons lang。其他所有内容均按照提供的范围进行。

            <dependency>
                <groupId>org.apache.cxf.karaf</groupId>
                <artifactId>apache-cxf</artifactId>
                <version>${cxf.version}</version>
                <classifier>features</classifier>
                <type>xml</type>
            </dependency>


            <dependency>
                <groupId>org.apache.commons</groupId>
                <artifactId>commons-lang3</artifactId>
                <version>3.3.2</version>
            </dependency>

在生成的 features.xml 文件中，commons 包已注册，但功能未注册：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<features xmlns="http://karaf.apache.org/xmlns/features/v1.2.1" name="feature">
    <feature name="feature" version="0.1-SNAPSHOT" description="test-feature">
        <details>test</details>
        <bundle start-level="80">mvn:com.test.test/test/0.1-SNAPSHOT</bundle>
        <bundle start-level="80">mvn:org.apache.commons/commons-lang3/3.3.2</bundle>
    </feature>
</features>

我想这样结束：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<features xmlns="http://karaf.apache.org/xmlns/features/v1.2.1" name="feature">
    <feature name="feature" version="0.1-SNAPSHOT" description="test-feature">
        <details>test</details>
        <feature version="3.0.2">cxf</feature>
        <bundle start-level="80">mvn:com.test.test/test/0.1-SNAPSHOT</bundle>
        <bundle start-level="80">mvn:org.apache.commons/commons-lang3/3.3.2</bundle>
    </feature>
</features>

轻微更新： 当我将<aggregateFeatures>true</aggregateFeatures> 添加到插件配置中时，整个 cxf 功能被解压缩到我的 features.xml 文件中，但是像“cxf”这样的功能依赖项仍然没有出现在生成的功能中。

Answer 1

恕我直言，这是 karaf-maven-plugin 中的错误或未完成的问题。我曾经也有过一样的问题。 对我来说，我找到的解决方案是在 src/main/feature 下添加一个 feature.xml 模板，其中包含我需要的功能和其他文件（配置文件）。在你的情况下会是这样的：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<features xmlns="http://karaf.apache.org/xmlns/features/v1.2.1" name="feature">
    <feature name="feature" version="${yourprojectversion}" description="test-feature">
        <feature version="${cxf.version}">cxf</feature>
    </feature>
</features>

我也用：<aggregateFeatures>true</aggregateFeatures>

请注意，在我的功能模板中，我使用了一些自定义 maven 属性来处理 pom.xml 中定义的版本。 最后，您将获得您期望的功能。

如果要将依赖项作为捆绑包包含在生成的 features.xml 文件中，则需要将依赖项标记为范围“运行时”。
