For declarative pipeline you can add this:

options {

    buildDiscarder(
        logRotator(
            // number of build logs to keep
            numToKeepStr:'5',
            // history to keep in days
            daysToKeepStr: '15',
            // artifacts are kept for days
            artifactDaysToKeepStr: '15',
            // number of builds have their artifacts kept
            artifactNumToKeepStr: '5'
        )
    )
}
