Jenkins Declarative Pipeline that Satisfy ALL, one value and multi-value option to run multiple stages

Jenkins pipeline that can accept multiple release values and an ALL option let's consider pipeline has 4 stages stage1 then stage 2 then stage3 and then stage 4 each is dependent on previous only to complete ex: ALL, 1,2,3,4,5 When we choose ALL, all 4 stages should run in parallel for 1,2,3,4,5 when we choose anyone for ex: 3 then all 4 stages should run in parallel for 3 we also should be able to multiple release values, example: 3 and 5 in this all 4 stages should run in parallel for 3 and 5 I tried matrix, and it's working for ALL options but not for selective, so I had to write duplicate stages for individual ones like below. But it doesn't support choosing multiple VERSION values, and code is not re-used effectively. Need help with code refactor to run it for multiple options and in parallel ``` pipeline { agent none parameters { string( name: 'BRANCH', defaultValue: '', description: '...') choice( name: 'VERSION', choices: ["ALL", "1", "2", "3", "4", "5"], description: 'Select version(s) for cluster deploy') } stages { stage('New Cluster') { when { expression { [login to view URL] == "ALL" } } matrix { axes { axis { name 'BASE_VERSION' values "1", "2", "3", "4", "5" } } Stages { stage (1){ ... } stage (2) { ... } stage (n) { ... } } } } stage('Desired Version Cluster') { when { expression { [login to view URL] != "ALL" } } Stages { stage (1){ ... } stage (2) { ... } stage (n) { ... } } } } } ```
