Subject Camel features using karaf feature xml
Date Mon, 14 Sep 2015 11:00:47 GMT
Hi,

How do I get camel features automatically installed by a feature xml.

In my scenario, I am creating my own Karaf feature xml to install all dependent bundles before
my bundles can be started. From what I observe, few camel features such as camel-core, camel-http4,
camel-jackson are installed while camel-blueprint does not get installed, this eventually
cause an issue starting my bundle.

Here is a simplified example.

1. Generate maven project
mvn archetype:generate \
-DarchetypeGroupId=org.apache.karaf.archetypes \
-DarchetypeArtifactId=karaf-feature-archetype \
-DarchetypeVersion=4.0.1 \
-DgroupId=com.acme.mediation \
-DartifactId=acme-mediation \
-Dversion=1.3.0-SNAPSHOT \
-Dpackage=com.acme.mediation \
-DinteractiveMode=false

2. Create feature xml as follow
[build@localhost EIP]$ cat acme-mediation/src/main/feature/feature.xml 
<?xml version="1.0" encoding="UTF-8"?>
<features name="${project.artifactId}-${project.version}" xmlns="http://karaf.apache.org/xmlns/features/v1.0.0">
	<repository>mvn:org.apache.camel.karaf/apache-camel/2.15.2/xml/features</repository>
    <feature name='${project.artifactId}-common' description='${project.name}' version='${project.version}'>
        <details>${project.description}</details>
	<feature version="2.15.2" prerequisite="true" dependency="true">camel</feature>
	<feature version="2.15.2" prerequisite="true" dependency="true">camel-blueprint</feature>
	<feature version="2.15.2" prerequisite="true" dependency="true">camel-jdbc</feature>
	<feature version="2.15.2" prerequisite="true" dependency="true">camel-http4</feature>
	<feature version="2.15.2" prerequisite="true" dependency="true">camel-jackson</feature>
    </feature>
</features>

3. Add following to pom.xml (I am using Nexus as MRM)
    <distributionManagement>
        <snapshotRepository>
            <id>snapshots</id>
            <url>http://localhost:8081/nexus/content/repositories/snapshots</url>
        </snapshotRepository>
    </distributionManagement>

4. Deploy the feature
mvn deploy

5. Install the feature in karaf (4.0.1)
dev@ubuntu:~/apache-karaf-4.0.1$ bin/karaf
karaf@root()> feature:repo-add mvn:com.acme.mediation/acme-mediation/1.3.0-SNAPSHOT/xml/features
karaf@root()> feature:install acme-mediation-common
karaf@root()> feature:list -i

* In this simplified example, I don’t get any of the specified camel features installed
even when I specified it in my feature xml.

Thanks and regards,
