Add support for Jenkins Blue Ocean #55
Description
Blue Ocean supports pull requests directly and uses a new version of the SCM plugin. This new version has changed the following environment variables used by codecov:
GIT_BRANCH has been replaced with BRANCH_NAME
GIT_COMMIT has no direct replacement (accessible only with Groovy)
SInce Blue Ocean no longer uses the GitHub Pull Request Builder plugin, all ghprb prefixed variables are not longer defined either, so:
ghrpbSourceBranch has been replaced with BRANCH_NAME
ghrpbActualCommit has no direct replacement (accessible only with Groovy)
ghprbPullId has been replaced with CHANGE_ID
The other environment variables are still available as before.
Here is a working Groovy implementation from the Docker team:
