I make use of the Bitbucket team project plugin for Jenkins and that plugin creates jobs in the format of

job/<BB-PROJECT>/job/<bb-repo>/job/<branch-name>

So for example:

job/FOO/job/bar/job/master

However, when a / exists in the branch name (for example, feature/test), we get something along the lines of

job/FOO/job/bar/job/feature%2Fbb-test

Now, this is totally fine, as it's just encoding the /, however when it gets sent over to Splunk the source appears as

job/FOO/job/bar/job/feature%252Ftest

So the % sign seems to be doubly encoded and instead of feature%2Fbb-test we get feature%252Ftest.

This causes a downstream impact where the Splunk App for Jenkins can't find the console logs (despite them existing) for any job where there is a / in the job name.
