  1. Compile project with maven

  * sample project: https://github.com/ctron/kura-examples/tree/master/camel/camel-example4

  1.1 Importing jar as dependency

  This is very ugly. The source project can not be identified. * https://www.tutorialspoint.com/maven/maven_external_dependencies.htm <code> <dependency> <groupId>ldapjdk</groupId> <artifactId>ldapjdk</artifactId> <scope>system</scope> <version>1.0</version> <systemPath>${basedir}\src\lib\ldapjdk.jar</systemPath> </dependency> </code>
