bnd-export-maven-plugin questions

I am using bnd-export-maven-plugin to generate a runnable jar, with the pom.xml defined as follows:

Unfortunately, I get the following error when launching the application:

randy@MacBook-Pro target % java -jar com.xyz.masterdata.application.services.jar

    ... 14 more

Note that I may use the referenced .bndrun file to launch the application just fine from within Eclipse, and the application is generated just fine when using gradle.

The maven command I used to build this runnable jar file is simply as follows:

mvn clean package

I have further extracted the content of the runnable jar file, with the following showing embedded jar files.

enter image description here

So it is clear the required jar files are not making it into the runnable jar file. But it is unclear to me why this is.

I am making the transition from gradle to maven, however, and seem to be stuck on this last item. Pointers for resolving are appreciated.

Thanks, Randy

Maybe you are missing a dependency to the felix framework. Not sure why it then works in bndtools though.

    <dependency>
        <groupId>org.apache.felix</groupId>
        <artifactId>org.apache.felix.framework</artifactId>
        <version>6.0.3</version>
    </dependency>

I think the problem is that you specify "-runfw: org.eclipse.osgi;version=3.13" which selects the equinox framework. You should use bndtools view to switch to the felix framework.

Maybe it works in eclipse as eclipse runs on equinox .. not sure.
