Variables defined in each stage, job or script cannot be passed. It would be nice if the variables can be defined in one stage/job/script only and they can be reused again..

For example:

project:project: 
key: EXAMPLE 
 plan:   
key: EXAMPLECI
name: EXAMPLE-CI
stages:

• jobs: 
• scripts:   
• '#!/bin/bash'   
• VERSION = 1.0.0
      interpreter: shell   
• jobs:   
• scripts:     
• '#!/bin/bash'
    // Variable $VERSION from previous job cannot be used here    
  interpreter: shell

Solution

Use Inject Variables task to pass variables across all phases of plan execution. This task can be defined in Bamboo Specs.
