Caching with SDK > 3.0 - No CachingProviders have been configured

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.

As requested by Emdee, here is the complete stack trace of the exception:

Update 2

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

Answer 1

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>
