NoClassDefFoundError when running local tests with only tenant-scp-neo included in POM

Question

Motivated by this blog entry , I tried to implement multitenancy for our existing application on the classic SAP Neo SCP.

I added the dependency

<dependency>
    <groupId>com.sap.cloud.s4hana.cloudplatform</groupId>
    <artifactId>tenant-scp-neo</artifactId>
    <version>1.9.5</version>
</dependency>

to my POM and accessed the tenant in a test program via

String tenantId = TenantAccessor.getCurrentTenant().getTenantId();

Then, I got this error

java.lang.NoClassDefFoundError: com/google/common/collect/Multiset
    at com.sap.cloud.sdk.cloudplatform.monitoring.ExceptionMonitor.<init>(ExceptionMonitor.java:30) ~[core-1.9.5.jar:na]

    at com.sap.cloud.sdk.cloudplatform.tenant.ScpNeoTenantFacade.<clinit>(ScpNeoTenantFacade.java:21) ~[tenant-scp-neo-1.9.5.jar:na]

How can I solve this issue?

Answer 1

After some investigation, it seems that the issue was a corrupt guava jar file in the Maven repository (within the .m2 folder). Deleting the respective folders and having Maven download them again fixed the issue.
