Hi Ed,
They should show up like:
344 | Active | 50 | 1.3.5 | jettison
345 | Active | 50 | 2.4.1 | Jackson-core
346 | Active | 50 | 2.4.1 | jackson-databind
347 | Active | 50 | 2.4.1 | Jackson-annotations
I’ve found the “dependency” is sometimes flaky and use the install=auto flag
when I want something to be installed
Here is my feature for Jackson:
<feature name="jackson" description="Jackson requirements for Karaf"
install="auto" version="2.5.4" resolver="(obr)">
<bundle>mvn:com.fasterxml.jackson.core/jackson-core/2.5.4</bundle>
<bundle>mvn:com.fasterxml.jackson.core/jackson-annotations/2.5.4</bundle>
<bundle>mvn:com.fasterxml.jackson.core/jackson-databind/2.5.4</bundle>
<bundle>mvn:com.fasterxml.jackson.jaxrs/jackson-jaxrs-json-provider/2.5.4</bundle>
<bundle>mvn:com.fasterxml.jackson.jaxrs/jackson-jaxrs-base/2.5.4</bundle>
<bundle>mvn:org.codehaus.jackson/jackson-jaxrs/1.9.13</bundle>
<bundle>mvn:org.codehaus.jackson/jackson-core-asl/1.9.13</bundle>
<bundle>mvn:org.codehaus.jackson/jackson-mapper-asl/1.9.13</bundle>
</feature>
I had to include the old codehaus jars for some CXF issues, hope this helps
Kind regards,
Jason

Subject: Understanding dependency in features.xml...
Hi. I am attempting to define bundles as dependencies, but am getting some
unexpected behaviour. My presumption is I don't understand how it's meant to
be used. The doco around this is short and sweet: "A bundle can be flagged as
being a dependency, using the dependency attribute set to true on the <bundle/>
element."
My interpretation is this means "If the bundle is not there already, install
it, I depend on it. If not, just use it". Perhaps I have interpreted it wrong.
I have a feature xml file that contains these definitions:
<feature name="jackson" version="2.5.4" description="Jackson libraries">
<bundle
dependency="true">mvn:com.fasterxml.jackson.core/jackson-core/2.5.4</bundle>
<bundle
dependency="true">mvn:com.fasterxml.jackson.core/jackson-annotations/2.5.4</bundle>
<bundle
dependency="true">mvn:com.fasterxml.jackson.core/jackson-databind/2.5.4</bundle>
<bundle
dependency="true">mvn:com.fasterxml.jackson.module/jackson-module-jaxb-annotations/2.5.4</bundle>
</feature>
<feature name="jackson-jaxrs" version="2.5.4" description="Jackson JAX-RS
libraries">
<bundle
dependency="true">mvn:com.fasterxml.jackson.jaxrs/jackson-jaxrs-base/2.5.4</bundle>
<bundle
dependency="true">mvn:com.fasterxml.jackson.jaxrs/jackson-jaxrs-json-provider/2.5.4</bundle>
</feature>
In the same file, I have a third feature that references these jackson features:
<feature name="my-core-bundles" version="1.0.4-SNAPSHOT">
<details>Features or bundles needed to support my code</details>
<feature version="1.0.2.RELEASE">gemini-blueprint</feature>
<feature version="4.0.0">war</feature>
<feature version="4.3.6.Final">hibernate</feature>
<feature version="2.5.4">jackson</feature>
<feature version="2.5.4">jackson-jaxrs</feature>
<feature version="3.1.0">cxf</feature>
<feature version="4.1.6.RELEASE_1">spring</feature>
<feature version="4.1.6.RELEASE_1">spring-jdbc</feature>
<feature version="4.1.6.RELEASE_1">spring-orm</feature>
<feature version="4.1.6.RELEASE_1">spring-tx</feature>
<feature version="1.2.1.RELEASE_1">spring-data-cassandra</feature>
<bundle
dependency="true">mvn:org.apache.commons/commons-math3/3.5</bundle>
<bundle dependency="true">mvn:com.hazelcast/hazelcast/3.5</bundle>
<bundle dependency="true">mvn:io.reactivex/rxjava/1.0.12</bundle>
</feature>
I can add my feature repository, and I can install my feature. And it works,
apparently without an error. If I list my installed features, it says the
Jackson features are started...
minestar-core-bundles | 1.0.4.SNAPSHOT | x | Started |
my-core-features-1.0.4-SNAPSHOT | myCore Bundles
jackson | 2.5.4 | | Started |
minestar-core-features-1.0.4-SNAPSHOT | Jackson libraries
jackson-jaxrs | 2.5.4 | | Started |
minestar-core-features-1.0.4-SNAPSHOT | Jackson JAX-RS libraries
However, the jackson bundles are not visible when I list the bundles. They're
not even installed. Anything I use which depends on Jackson won't resolve
because it can't find anything.
If I define my Jackson feature without the "dependency" attribute, it works
more like I expected.
Is my understanding of what the dependency attribute for a bundle in the
features.xml incorrect? If not, am I doing something else incorrectly?
Thanks for any help,
Ed
