How can I cache Sonar plugins in Azure DevOps Pipelines so that they don't download everytime the pipeline runs?

I use the Sonar tasks in my Azure DevOps pipeline to run static analysis on my code, but I would like to avoid having the pipeline download the plugins everytime the pipeline runs.

I think I could use the Cache task but I'm not sure how should I configure it.

Solution

  • I was facing the same issue. My pipeline was downloading the Sonar plugins every time and taking about 40~60 seconds.

    I was able to cache the plugins through the .sonar/cache folder and decrease the download time to around 8~12 seconds.

    Example:

    variables:
  SONAR_PLUGINS: /home/vsts/.sonar/cache

steps:
  - task: Cache@2
    inputs:
      key: sonar | "$(Agent.OS)" | $(Build.Repository.Name)
      path: $(SONAR_PLUGINS)
    displayName: cache sonar plugins
