Hi All,
Once I added the jollyday and joda-time as dependecies to the pom and
embedded those dependencies from the felix plugin this problem got solved.
dependencies:
<dependency>
<groupId>de.jollyday</groupId>
<artifactId>jollyday</artifactId>
<version>0.4.7</version>
</dependency>
<dependency>
<groupId>joda-time</groupId>
<artifactId>joda-time</artifactId>
<version>2.1</version>
</dependency>
felix plugin:
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>1.4.0</version>
<extensions>true</extensions>
<configuration>
<instructions>
<Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
<Bundle-Name>${project.artifactId}</Bundle-Name>
<Export-Package>
edu.stanford.nlp.*; version="3.4",
</Export-Package>
<Import-Package>
*;resolution:=optional
</Import-Package>
<DynamicImport-Package>
*
</DynamicImport-Package>
<Embed-Dependency>jollyday,joda-time</Embed-Dependency>
</instructions>
</configuration>
</plugin>
It seems to me that we have to embed any dependency used by the library at
the invocation.
Welcome any comments or thoughts on this solution.
Thank You.
Malithi.
