How to properly import/export dependencies in Karaf?

I have a simple servlet that calls AmazonS3Ciient class 

my pom.xml 

<plugin>
				<groupId>org.apache.felix</groupId>
				<artifactId>maven-bundle-plugin</artifactId>
				<extensions>true</extensions>
				<configuration>
					<supportedProjectTypes>
						<supportedProjectType>jar</supportedProjectType>
						<supportedProjectType>bundle</supportedProjectType>
						<supportedProjectType>war</supportedProjectType>
					</supportedProjectTypes>
					<instructions>
						<Bundle-SymbolicName>${bundle.symbolicName}</Bundle-SymbolicName>
						<Bundle-Version>${project.version}</Bundle-Version>
						<Import-Package>
						   com.amazonaws.*,
							*;resolution:=optional
						</Import-Package>
						<Export-Package>
							!*
						</Export-Package>
						<Bundle-Classpath>
							WEB-INF/classes
						</Bundle-Classpath>
						<Web-ContextPath>agwar</Web-ContextPath>
					</instructions>
				</configuration>
				<executions>
					<execution>
						<id>generate-manifest</id>
						<phase>process-classes</phase>
						<goals>
							<goal>manifest</goal>
						</goals>
					</execution>
				</executions>
			</plugin>
			<plugin>
				<artifactId>maven-war-plugin</artifactId>
				<configuration>
					<archive>
					
<manifestFile>${project.build.outputDirectory}/META-INF/MANIFEST.MF</manifestFile>
					</archive>
				</configuration>
			</plugin>

I'm getting the error noclassdeferror I believe it is a missing dependency
or dependency conflict?


I tried to find the class and it is present on both bundle

karaf@root()> find-class AmazonS3Client

Apache ServiceMix :: Bundles :: aws-java-sdk (133)
com/amazonaws/services/s3/AmazonS3Client$1.class
com/amazonaws/services/s3/AmazonS3Client$2.class
com/amazonaws/services/s3/AmazonS3Client$3.class
com/amazonaws/services/s3/AmazonS3Client.class

OPS4J Pax Web - Samples - Servlet3 (139)
com/amazonaws/services/s3/AmazonS3Client$1.class
com/amazonaws/services/s3/AmazonS3Client$2.class
com/amazonaws/services/s3/AmazonS3Client$3.class
com/amazonaws/services/s3/AmazonS3Client.class


Not really sure how to resolve this :(

Thanks in advance
