Problem
Sometimes the coverage reporting will report on source files that really shouldn't be in the coverage report, giving wildly skewed results. See #1749 for an example of somebody reporting this issue or see the following screenshot where I ran into this today while working on a Minecraft modding project (the coverage reporter is reporting on the Minecraft source code in addition to my own).
Solution
Add a new configuration option:
java.test.config.coverage.excludes. This option supports any "globbing" pattern supported by minimatch internally since it's used for the pattern matching support. Run the list of files returned by the coverage provider through this pattern matcher set. Only provide coverage results from the total set that aren't excluded by the patterns.Empty lists will still return all coverage results, see the below screenshot.
See the below screenshots for examples of working patterns.
Filtering the entire build directory.
Filtering only one path out of several.
Multiple path filters.
