jenkinsci / caliper-ci-plugin Goto Github PK

Hey, sorry I haven't debugged this more, but...

The plugin has been barfing for me in the deserialization of results files. eg (from jenkins main log)

Could not parse file as JSON, skipping: com.lcgerke.lcgutil.caliperexample.ListIterationBenchmark.2014-05-01T21:02:48Z.json

....

I tried to clone the project to verify that parsing was working in tests, but in an unmodified clone, i got the following on "mvn test" (linux, maven3).

It doesn't look exactly the same, but I'm wondering if there might be some global JSON parsing issue. Any thoughts, before I try to start debugging it myself?

Thanks for your hard work.
