How make UpdateCLI "silent" when no changes are needed?

[ringods]

Hello,

I have the following UpdateCLI manifest (as part of a policy in development):

# {{ $DefaultTitle := "Bump upstream CRD version" }}

name: '{{ default $DefaultTitle .title }}'

# {{ if .pipelineid }}
pipelineid: '{{ .pipelineid }}'
# {{ end }}

scms:
  default:
    kind: github
    spec:
      owner: {{ .scm.owner }}
      repository: {{ .scm.repository }}
      token: {{ requiredEnv .scm.env_token }}
      username: {{ .scm.username }}
      branch: {{ .scm.branch }}

sources:
  upstream:
    kind: githubrelease
    spec:
      owner: {{ .upstream.owner }}
      repository: {{ .upstream.repository }}
      versionfilter:
        kind: semver
        pattern: {{ requiredEnv .upstream.env_version }}
      token: {{ requiredEnv .upstream.env_token }}
    transformers:
      - trimprefix: "v"

targets:
  apply-to-projen:
    name: "Update CRD version in .projenrc.json"
    kind: json
    sourceid: upstream
    scmid: default
    spec:
      engine: "dasel/v2"
      file: ".projenrc.json"
      key: "latestVersionOnBranch"

actions:
  default:
    # The action title is used to define the pullrequest title
    # Since we use the groupby set to all we need to be sure that the pullrequest title
    # is the same for all the pipeline generated by autodiscovery.
    title: Bump upstream CRD version
    kind: github/pullrequest
    scmid: default
    spec:
      labels:
        - "dependencies"

In upstream, the environment variable defined by .upstream.env_version points to a specific semantic version and comes from an outside process. If that version is different than the version defined in a JSON property in my target, then update it and create a PR.

Now, if the values are NOT different, e.g. subsequent runs, I want to let the run stop, but not with an error. I looked into conditions, tried a few setups, but couldn't get a setup working. Any suggestions from the community?

Have you tried a condition with a failwhen setting?
Something like

name: "test"
conditions:
  failed:
    name: Failed
    kind: json
    failwhen: true
    spec:
      file: "/tmp/data.json"
      engine: "dasel/v2"
      key: .age
      value: "13"

Then set failwhen to false or true depending on the situation
As mentionned on https://www.updatecli.io/docs/core/condition/
The failwhen allows to revert the expected condition result

Thanks @olblak !!

My workflow now ends normally (meaning "without error") skipping the regeneration and PR creation as I want it. 🙏🏻
