Karaf-maven-plugin: defining dependency as a function

I am trying to get karaf-maven-plugin to create a function file for my application. The application depends on the cxf function, but I cannot get the plugin to generate the xml function to reflect this.

Cutout from my function module:

<dependencies> <dependency> <groupId>com.test.test</groupId> <artifactId>test</artifactId> </dependency> </dependencies> <build> <pluginManagement> <plugins> <plugin> <groupId>org.apache.karaf.tooling</groupId> <artifactId>karaf-maven-plugin</artifactId> <version>3.0.3</version> <extensions>true</extensions> </plugin> </plugins> </pluginManagement> <plugins> <plugin> <groupId>org.apache.karaf.tooling</groupId> <artifactId>karaf-maven-plugin</artifactId> <configuration> <startLevel>80</startLevel> <includeTransitiveDependency>true</includeTransitiveDependency> <aggregateFeatures>false</aggregateFeatures> </configuration> </plugin> </plugins> </build>

Dependencies on my module:

  <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.osgi</groupId> <artifactId>org.osgi.core</artifactId> <version>5.0.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.osgi</groupId> <artifactId>org.osgi.compendium</artifactId> <version>5.0.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.apache.felix</groupId> <artifactId>org.apache.felix.configadmin</artifactId> <version>1.8.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.2.8</version> <scope>provided</scope> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-frontend-jaxrs</artifactId> <version>${cxf.version}</version> <scope>provided</scope> </dependency> <!-- use extension providers --> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-rs-extension-providers</artifactId> <version>${cxf.version}</version> <scope>provided</scope> </dependency> <!-- use Jackson --> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-jaxrs</artifactId> <version>1.9.13</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-xc</artifactId> <version>1.9.13</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-transports-http</artifactId> <version>${cxf.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-ws-security</artifactId> <version>${cxf.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-ws-policy</artifactId> <version>${cxf.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-ws-addr</artifactId> <version>${cxf.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-frontend-jaxws</artifactId> <version>${cxf.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-rs-client</artifactId> <version>${cxf.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-transports-http-hc</artifactId> <version>${cxf.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.apache.cxf.karaf</groupId> <artifactId>apache-cxf</artifactId> <version>${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> </dependencies>

As you can see, I tried to define the artifact of the function as a compilation-dependent area, as well as commons lang. Everything else is limited as provided.

  <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>

The commons package is registered in the resulting features.xml file, but the function is missing:

 <?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>

I would like to end up with:

 <?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>

Small update: When I add <aggregateFeatures>true</aggregateFeatures> to the plugin configuration, the whole cxf function is unpacked into my features.xml file, but function dependencies like "cxf" still do not appear in the genetic function.

IMHO this is something wrong or not completed in karaf-maven-plugin. I had the same problem. For me, the solution I found is to add the feature.xml template to src / main / feature, just with the functions and other configfiles I need. In your case, it will be something like this:

 <?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>

I also use: <aggregateFeatures>true</aggregateFeatures>

Please note that in my property template I use some custom maven properties for version handling defined in pom.xml. In the end, you will get the function that you expect.
