Regex in Jenkins pipeline
You can use String.startsWith(str) that returns true if env.GERRIT_PROJECT starts with platform/zap.
stage ('zap') { when { expression { env.GERRIT_PROJECT?.startsWith("platform/zap") } } steps { build job: 'Zap', parameters: [ string(name: 'ZAP_PROJECT', value: env.GERRIT_PROJECT) ] }}To avoid NPE if env.GERRIT_PROJECT is null for some reason, you can use NPE-safe operator ?. to invoke startsWith method.
The alternative solution that uses Groovy's exact match operator with regex could look like this:
stage ('zap') { when { expression { env.GERRIT_PROJECT ==~ /^platform\/zap(.*)$/ } } steps { build job: 'Zap', parameters: [ string(name: 'ZAP_PROJECT', value: env.GERRIT_PROJECT) ] }}

Execute the stage when the specified environment variable is set to the given value, for example: when { environment name: 'DEPLOY_TO', value: 'production' }
Maybe this can help?
