Looks like something to with 'retry' class in resilience jar. Please let me know the solution.

Answer 1

java.lang.ClassNotFoundException: io.github.resilience4j.core.IntervalBiFunction

It seems there is a version conflict in your dependency setup of your pom.xml. Please run mvn dependency:tree and investigate. Make sure resilience4j-core has one version referenced only. Use <exclusions> to avoid an old transitive version or <dependencyManagement> / <dependency> to enforce a specific version of Resilience4j.

Please find this guide on dealing with dependency conflicts in the SAP Cloud SDK documentation.
