Cannot upload coverage if not using GOPATH for Go projects.

[F21]

I am using Go 1.11 with Go modules. When Go modules are used, it's possible to build projects outside of the GOPATH. For example, rather than placing the project inside /pipeline/source/github.com/user/repo, we can clone the project directly into /pipeline/source.

The test-reporter currently does not support this. It throws an error because it's looking for files in the github.com/user/repo folder when the files are directly in the /pipeline/source folder:

Usage:
  cc-test-reporter after-build [flags]

Flags:
  -s, --batch-size int               batch size for source files (default 500)
  -e, --coverage-endpoint string     endpoint to upload coverage information to (default "https://api.codeclimate.com/v1/test_reports")
  -t, --coverage-input-type string   type of input source to use [clover, cobertura, coverage.py, excoveralls, gcov, gocov, jacoco, lcov, simplecov]
      --exit-code int                exit code of the test run
  -r, --id string                    reporter identifier (default "2bc093d2d74702b0e5ebc9bbb0d38136b6dc2780b24e47250a5d963b3c881361")
      --insecure                     send coverage insecurely (without HTTPS)
  -p, --prefix string                the root directory where the coverage analysis was performed (default "/pipeline/source")

Global Flags:
  -d, --debug   run in debug mode

@F21 test-reporter is parsing the content on the c.out file, which probably has on it the full file paths. You could use the --prefix flag to remove github.com/Boostport/ and the test-reporter will be able to find the files. The invocation would look something like

cc-test-report after-build --prefix github.com/Boostport/

Thanks @ale7714. --prefix github.com/Boostport/address/ worked for me! 😄
