Hi all,
I encountered a problem while running the nemo project. I added the following third-party dependencies in my pom file:
<dependency>
<groupId>net.sourceforge.collections</groupId>
<artifactId>collections-generic</artifactId>
<version>4.01</version>
</dependency>
<dependency>
<groupId>net.sf.jung</groupId>
<artifactId>jung-api</artifactId>
<version>2.0.1</version>
</dependency>
<dependency>
<groupId>net.sf.jung</groupId>
<artifactId>jung-graph-impl</artifactId>
<version>2.0.1</version>
</dependency>
<dependency>
<groupId>net.sf.jung</groupId>
<artifactId>jung-algorithms</artifactId>
<version>2.0.1</version>
</dependency>
The project could be built successfully, but when I ran the project and installed my feature, I got the following error:
Error executing command: Can't install feature odl-nemo-engine/0.0.0:
Could not start bundle mvn:org.opendaylight.nemo/nemo-impl/1.0.0-SNAPSHOT in feature(s) odl-nemo-engine-1.0.0-SNAPSHOT: The bundle "org.opendaylight.nemo.impl_1.0.0.SNAPSHOT [166]" could not be resolved. Reason: Missing
Constraint: Import-Package: edu.uci.ics.jung.algorithms.filters; version="0.0.0"
Then, I added the following configuration in the pom file and solved this problem.
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Bundle-ClassPath>.,{maven-dependencies}</Bundle-ClassPath>
<Import-Package>*;resolution:=optional</Import-Package>
<Export-Package>*</Export-Package>
<Embed-Dependency>*</Embed-Dependency>
<Embed-Transitive>true</Embed-Transitive>
<Embed-Directory>lib</Embed-Directory>
<Embed-StripGroup>true</Embed-StripGroup>
<_failok>true</_failok>
<_nouses>true</_nouses>
</instructions>
<manifestLocation>${project.build.outputDirectory}/META-INF</manifestLocation>
</configuration>
</plugin>
But when I ran the project again, I got an exception as follows:

Is there anybody can help me and give me some suggestions? Thanks so much!
