Hello,

I have a plugin for Cytoscape 3.0 with a dependency on the external library
org.apache.commons.math (2.1)
Compilation is ok but at runtime the dependency jar is not getting deployed
or bundled when starting Cytoscape 3.0:

org.osgi.framework.BundleException: Unresolved constraint in bundle
org.cytoscape.dyn [48]:
Unable to resolve 48.0: missing requirement [48.0] package;
(&(package=org.apache.commons.math)(version>=2.1.0)(!(version>=3.0.0)))

The dependency is specified as a Maven dependency in the pom file:

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-math</artifactId>
    <version>2.1</version>
</dependency>

How can I fix this?
Thanks in advance,

Sabina

Hi Sabina,

You can bundle your dependencies in your app JAR by adding the following
snippet to your pom.xml:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.felix</groupId>
            <artifactId>maven-bundle-plugin</artifactId>
            <version>${maven-bundle-plugin.version}</version>
            <configuration>
                <instructions>
                    ...

<Embed-Dependency>commons-math;groupId=org.apache.commons;inline=true</Embe d-Dependency>
                    <Import-Package>*;resolution:=optional</Import-Package>
                    ...
                </instructions>
            </configuration>
        </plugin>
    </plugins>
</build>

The other alternative is to use Bnd to wrap commons-math as an OSGi bundle
and distribute that with your app bundle.  Unfortunately, the App Store
doesn't currently support multi-bundle apps yet, so you wouldn't be able to
distribute your app through that channel.  Embedding the dependency as
described above is probably the best thing to do for now.

Hope this helps,
Jason
