Use Node Version in key for Cache@2 Azure Devops task-CodePudding

Based on the documentation for the Cache@2 task we set this key for the task:

- task: Cache@2
  inputs:
    key: 'npm | "$(Agent.OS)" | package-lock.json | package.json'
# etc.

Just before that we've installed Node with:

- task: NodeTool@0
  inputs:
      versionSpec: '16.x'
  displayName: 'Install Node.js'

How can I use the version of Node on the Agent as a part of the key? Is there something like Agent.NodeVersion, and where could I find the documentation on available variables?

CodePudding user response：

Would've preferred to use a built-in variable, but for now I solved it with:

variables:
  NodeVersionSpec: 16.x

- task: NodeTool@0
  inputs:
      versionSpec: $(NodeVersionSpec)
  displayName: 'Install Node.js'

- task: Cache@2
  inputs:
      key: 'npm | "$(NodeVersionSpec)" | "$(Agent.OS)" | package-lock.json | package.json'
      restoreKeys: |
          npm | "$(Agent.OS)"
          npm
      path: $(npm_config_cache)
  displayName: Cache npm
