Command line like this:
java -jar jenkins-plugin-manager-1.0.1.jar -f plugins.txt --verbose --plugin-download-directory ~/plugins --no-download --list --war /usr/lib/jenkins/jenkins.war --jenkins-update-center https://jenkins-updates.cloudbees.com/
fails with stack trace containing
java.io.FileNotFoundException: https://jenkins-updates.cloudbees.com//update-center.json
Remove the trailing slash from the desired update center and it accepts the supplied update center. (This is the workaround)

If you are still encountering this error, could you post the full stack trace as well as the plugins.txt file you are using? Thanks.
Edit: based on minimal testing, it looks like it might be a a specific issue with the jenkins-updates.cloudbees.com update center. Using another update center, with and without a trailing slash, doesn't seem to recreate the error.
