java.lang.NoClassDefFoundError: eu/chargetime/ocpp/wss/WssSocketBuilder

Hello Thomas,
I build your code to these two jars:
common-0.5-SNAPSHOT.jar and v1_6-0.5-SNAPSHOT.jar

Then I took the jars and added in my project. The classes is found by IntelliJ perfectly fine.

But when I run the project I get a ClassDefFoundError

Exception in thread "main" java.lang.NoClassDefFoundError: eu/chargetime/ocpp/wss/WssSocketBuilder
at OcppDriver.connect(OcppDriver.java:121)

which is the following line of code of your JSONClientSample:

client = new JSONClient(core);

Do you have any suggestion what I am doing wrong?

EDIT:
After I added the OCPP-J-0.5-SNAPSHOT.jar the code seems to run.

Hi @pepperonas! I am running into a similar issue and wanted to know how did you build the project to get those 3 JAR files (and where would they be located after building)? Thank you.

Hi,

Sorry for my unresponsiveness. It looks like you found the class, which is located in the OCPP-J module. I split them up some time ago.

If you build the project from the root folder using mavens mvn install, then the jars should be placed in your maven cache.
If you use maven to build the project, then having the jars in the maven cache should work, but if you want to find the files you can find the cache here: https://www.baeldung.com/maven-local-repository

Hi @pepperonas,

Did I solve your problem? If so, can I get you to close the issue?
