I'm trying to create a bundle using HttpService for register Servlet using maven-bundle-plugin.
The pom.xml of the project is:

In the configuration of the maven-bundle-plugin you have to specify all the packages you need to import.
In your case it should be:
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
...
<Import-Package>org.osgi.service.http, org.osgi.framework;version="1.0.0", javax.servlet, javax.servlet.http</Import-Package>
</instructions>
</configuration>
</plugin>
The given answer is wrong. You don't need to specify ALL the packages you need to import. Simply put a * at the end of your instruction to import (without version definition) the missing packages:
<Import-Package>org.osgi.framework;version="1.0.0", javax.servlet, javax.servlet.http**,***</Import-Package>
Use the newer bundle version: org.apache.felix maven-bundle-plugin 2.0.0 true
