[keycloak-user] Keycloak 3.4.3, custom SPI deployment: noclassdef-error caused by ClassNotFoundException when trying to call LDAPStorageProvider

Hi everyone, sorry for spamming, but I have another problem here: I am using maven to deploy my jar-file to keycloak 3.4.3. I added the dependencies for kerberos and ldap federation like this (with and without scope provided): <dependency> <groupId>org.keycloak</groupId> <artifactId>keycloak-kerberos-federation</artifactId> <version>3.4.3.Final</version> </dependency> <dependency> <groupId>org.keycloak</groupId> <artifactId>keycloak-ldap-federation</artifactId> <version>3.4.3.Final</version> </dependency> In my IDE I can call the Classes in Question, e.g. LDAPStorageProvider, but when the jar is successfully deployed to keycloak, I get the following exception when my method is called: ...Caused by: java.lang.ClassNotFoundException: org.keycloak.storage.ldap.LDAPStorageProvider from [Module "deployment.ldap-authenticator.jar" from Service Module Loader] I looked in modules/...keycloak/ and saw all jars lying there in version 3.4.3.Final, I even looked inside with jar -tf, and the class in question is provided. As said, I tried to use scope provided and no scope, without effect. Apart from that, I changed the module.xml for the private jars by removing the private part from them and restarting the kc server, but without any effect. At this link u can see the build-definition of my pom.xml: https://pastebin.com/xgHdSGFa So, am I missing something? Hope anyone could help me out here. :/
