  • Post the complete and exact error message, as text. I can't even see what error you're talking about in your picture. – JB Nizet Aug 19 '13 at 12:39
  • In the second screenshot, the root package (`com`) has a blue folder icon which means you have set it as a "Source Root", when its parent folder (`benchmark`) is already set (correctly) as a "Source Root". Right-click on `com`, "Mark Directory As" / "Unmark as Source Root". – Frank Pavageau Aug 19 '13 at 12:44
  • Actually, `benchmark` should be marked as a "Test Source Root", not a "Source Root". – Frank Pavageau Aug 19 '13 at 12:46
  • @FrankPavageau I change to bechmark maked as a "Test Source Root" – fuyou001 Aug 19 '13 at 14:14

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.

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
$

    That's my point: _you can't_. Google has not released a version of Caliper with that class, the benchmarks are used internally and cannot be built with the publicly available tools & libs. – Frank Pavageau Aug 20 '13 at 07:39

    That's not exactly true.... it's in no release, but it's in the git repository already: commit 439ca07, 2013-06-21. – maaartinus Aug 20 '13 at 08:21
  • @maaartinus my bad, I didn't check the available code for Caliper. I think the step-by-step answer to set up the necessary environment (with local modifications to Guava's pom.xml) is a bit out of the SO scope, though... – Frank Pavageau Aug 20 '13 at 08:58
  • No idea how to do it with Maven, etc.; this might get complicated. In Eclipse I simply created a separate project and added it to Java Build Path. – maaartinus Aug 20 '13 at 09:25
  • @maaartinus would you give me the git repository.Thanks! – fuyou001 Aug 22 '13 at 00:56
  • @fuyou001: I can't, as it's not mine. :D But it's free: `git clone https://code.google.com/p/caliper/`, see [here](http://code.google.com/p/caliper/source/checkout). – maaartinus Aug 25 '13 at 13:44
