Find mechanism to aggregate measure and results

[romanowski]

Each run of community build will provide a lot of data. We want to find a mechanism to aggregate and store that data.

There is not hard stop how many features we would like to have so I split them into 'must have' and 'nice to have'.

Must have

• allow to gather and aggregate data on few levels (run of community build, build of a single project and finally run of single target)
• gather numerical data like no. of warning, errors, failed tests or line compiled. It should also include compilation speed, times, or sizes generated .classes and .jar files
• allow to report data from distributed build
• allow to aggregate across different runs (e.g. we want to display time of compilation for given project across many builds)
• generating reports should be easy
• easy way to anonymize data

** nice to have **

• ability to track failures of single test
• ability to track compilation problems / warning

We would prefer to use some lightweight solution.
