java.lang.NoClassDefFoundError with Netbeans and maven project #15

Hi, I'm experimenting a problem with my project including californium lib. I added repositories and dependency in my pom.xml. Compilation is OK. But when I run the application there is the following error Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/californium/core/CoapClient I noted that in lib folder there is the file californium-core-1.0.0-SNAPSHOT.jar but in MANIFEST.MF in classpath it's reported as lib/californium-core-1.0.0-20140715.144519-3.jar (the last part changes at any new recompilation date/hour). Changing manually the path in MANIFEST.MF the previous problem is fixed but I have

Create standard properties with file Californium.properties Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/californium/elements/Connector

Maybe I'm missing something. Can you help me? Thanks

Are you using OSGi?

mcicolella commented 10 years ago

No. My code is available at https://github.com/mcicolella/freedomotic/tree/coap-client/plugins/devices/coap-client

Might be related to this bug in maven-jar-plugin. Try either the proposed workaround (add <useUniqueVersions>false</useUniqueVersions> at https://github.com/mcicolella/freedomotic/blob/coap-client/pom.xml#L520) or try a different version of the maven-jar-plugin.
