Caching with SDK > 3.0 - No CachingProviders have been configured - sap-cloud-sdk

Question

I am trying to make some cached backend calls with the java SDK version 3.9.0. The only resource I found concering caching with the SDK version > 3.0.0 was the official release notes and this replay video of a community update call back in september.
After more or less copying the code from the video and adjusting it for my purposes I came up with the following to try caching myself:
private final ResilienceConfiguration configuration;
private final String purchaseOrder;
public GetSupplierFromPOCommand(String purchaseOrder) {
this.purchaseOrder = purchaseOrder;
this.configuration = ResilienceConfiguration.of(GetSupplierFromPOCommand.class)
.cacheConfiguration(ResilienceConfiguration.CacheConfiguration.of(Duration.ofHours(1)).withParameters(purchaseOrder));
}
public PurchaseOrder execute() {
logger.info("Running " + this.getClass().getName() + " ...");
Callable<PurchaseOrder> poCallable = ResilienceDecorator.decorateCallable(this::run, configuration);
try {
return poCallable.call();
} catch (Exception e) {
throw new RuntimeException("Failed to retrieve purchase order", e);
}
}
private PurchaseOrder run() throws ODataException {
Destination destination = DestinationAccessor.getDestination(DESTINATION_NAME);
return new DefaultPurchaseOrderService()
.getPurchaseOrderByKey(purchaseOrder)
.select(PurchaseOrder.SUPPLIER)
.execute(destination.asHttp());
}
However, when I try to run this command I get the following exception javax.cache.CacheException: No CachingProviders have been configured. As suggested by the release notes I added caffeine as a JCache implementation as a dependency to my application pom, but the error still remains the same.
The question is, what am I doing wrong here? Any help is appreciated.

Dependency tree via mvn dependency:tree. Unfortunately the output is too large for stack overflow, so I created this paste bin: https://pastebin.com/tu0HFi5B

Checking out the blog post about migration to the SAP Cloud SDK, it reveals that the following dependency is needed:
<dependency>
<groupId>com.github.ben-manes.caffeine</groupId>
<artifactId>jcache</artifactId>
<version>2.7.0</version>
</dependency>
