Our bundle can not load a dependent bundle (fasterxml).
Solution:
1. Check feature if the bundle dependency is declared:
<feature name="sd-server" version="${pom.version}">
<!--
<feature>http</feature>
-->
<feature>http-whiteboard</feature>
<feature>cxf-features-logging</feature>
<feature>cxf-jaxrs</feature>
<feature>cxf-rs-security-cors</feature>
<feature>cxf-jackson</feature> <-------- here it is
<feature>cxf-commands</feature>
<feature version="[4.3, 5.4)">hibernate</feature>
<!--
<bundle dependency="true">mvn:com.gtarc.servicedirectory.model.service/service-model/${pom.version}</bundle>
-->
<feature>sd-model</feature>
<bundle start-level="80">mvn:com.gtarc.servicedirectory.server.rest/sd-rest/${pom.version}</bundle>
<bundle start-level="80">mvn:com.gtarc.servicedirectory.server.rest/jiac-rest-server/${pom.version}</bundle>
</feature>
2. Check if the dependency is declared when building our bundle:
In our bundle's pom:
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Import-Package> com.fasterxml.jackson.* </Import-Package>
... ... ...
</instructions>
</configuration>
</plugin>
3. If changed, refresh are reload:
Rebuild feature:
mvn clean install
Reload karaf:
karaf@root()> feature:repo-refresh mvn:com.gtarc.servicedirectory/sd-feature/1.0.0/xml/features 16:25:31 Refreshing feature url mvn:com.gtarc.servicedirectory/sd-feature/1.0.0/xml/features karaf@root()> feature:install sd-all-test
