Manipulating Jenkins build parameter with groovy script, used for sonar analysis - groovy

Question

At the moment, i have Sourcetree making my branches, they will be called "feature/my-branch" and i can send that to my hg repo, and retrieve it from jenkins and build.
but, sonar does not accept "/" in the branch name, so i wanted to change "/" to "-" or something.. in a groovy script in the build phase.
Is something like that possible?
my solution so far:
parameter: BRANCH
default value: feature/my-branch
groovy scrips: def replaced = BRANCH.replaceAll(/\//, '-')
but it will not recognize my BRANCH, i've tried adding it in all sorts of ways..
any help to make my "feature/my-branch" be analyzed by sonar will be appreciated.

How are you invoking SonarQube on Jenkins? I assume it's via the SonarQube Jenkins Plugin. You could use the EnvInject Plugin to edit BRANCH. Here's an untested possibility for you to mull over:
SONAR_BRANCH=${BRANCH//\//-}
And in the SonarQube plugin's "Additional options":
sonar.branch=${env.SONAR_BRANCH}
If that won't work, or if you don't want EnvInject, you could do everything in one Execute Shell build step:
SONAR_BRANCH=${BRANCH//\//-}
mvn sonar:sonar -Dsonar.branch=${SONAR_BRANCH}
