Was it helpful?

Solution

The guava-tests/benchmark directory is currently not set as a source root in the Maven configuration because it won't build. That said, we just need to push a new version of Caliper to Maven Central that includes the new annotations and such, and I think that should be happening sometime soon.

OTHER TIPS

No publicly available version of Caliper contains the com.google.caliper.BeforeExperiment class.

You can compare the result of the following class searches on search.maven.org for yourself:

You can also check what's in your jar:

$ jar tf ~/.m2/repository/com/google/caliper/caliper/0.5-rc1/caliper-0.5-rc1.jar | \
    grep -E com.google.caliper.B | sort
com/google/caliper/Benchmark.class
$

Or using the most recent "release" of Caliper:

$ jar tf caliper-1.0-beta-1.jar | grep -E com.google.caliper.B | sort
com/google/caliper/Benchmark.class
$
