Hi Moquette Team,

I'm currently trying to include an embedded version of moquette into my spring boot app. I added the repository link and dependency to my pom.xml, but when i try to run it I get the following errors at mqttBroker.startServer(classPathConfig, userHandlers);:

Exception in thread "main" java.lang.NoClassDefFoundError: org/mapdb/DBMaker at io.moquette.spi.persistence.MapDBPersistentStore.initStore(MapDBPersistentStore.java:97) at io.moquette.spi.impl.SimpleMessaging.init(SimpleMessaging.java:86) at io.moquette.server.Server.startServer(Server.java:125) at io.moquette.server.Server.startServer(Server.java:110) at com.comm.pubsub.mqtt.moquette.EmbeddedLauncher.start(EmbeddedLauncher.java:46) at com.comm.pubsub.ServerApplication.main(ServerApplication.java:49) Caused by: java.lang.ClassNotFoundException: org.mapdb.DBMaker at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357)

I assume this is caused by a missing DBMaker dependency, but when I include the maven link

org.mapdb mapdb 1.0.8 i still get the same error. My IDE does not yield any pre compile errors (like missing / unknown includes). Am I missing something? (I guess so, but what? :D) In case thats helpful, im using STS on a windows 10 machine.

Thanks for your help Thomas

Edit: Im using a slightly edited version of your code from here

If you do mvn dependency:tree to see how maven resolves, which is the output? This seems strange it look like the dependency in you pom is scope runtime

@Klarzahs could you try with version 0.9? To reprodcue I just need to create a plain maven Spring boot app and add the Moquette dependency?
