Why would this not work ? - No CachingProviders have been configured

[Narahari Lakshminarayana]

Friends:

I have the following code that is not working.

@Grapes(
    @Grab(group='org.mnode.ical4j', module='ical4j', version='3.0.20')
)
@Grapes(
    @Grab(group='javax.cache', module='cache-api', version='1.1.1')
)
@Grapes(
    @Grab(group='com.github.ben-manes.caffeine', module='caffeine',
version='2.8.6')
)

import javax.cache.spi.*;
import javax.cache.*;
import javax.cache.configuration.*;
import com.github.benmanes.caffeine.*;

CachingProvider cachingProvider = Caching.getCachingProvider();

I get the following error

javax.cache.CacheException: No CachingProviders have been configured

===================

Not sure what is wrong in the above code.

Please help.
