Answer 1

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.

Answer 2

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:

• com.google.caliper.BeforeExperiment
• com.google.caliper.Benchmark

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
$
