fix(build-test-sonar)!: Authenticate Sonar scanner with sonar.token by kploch · Pull Request #3 · mrploch/ploch-github-actions

kploch · 2026-08-22T16:07:41Z

Summary

build-test-sonar supplied the SonarCloud credential only as the sonar.login analysis property. sonar.login was deprecated in favour of sonar.token and is no longer honoured by the current SonarScanner engine, so the scanner authenticated anonymously and post-processing failed at Create analysis with a misleading Not authorized or project not found.

Because the token was interpolated correctly (it appears masked as *** in run logs), this failed silently rather than erroring on a missing input, which is why it read as an account/permissions problem and sent people to the SonarCloud administration screens.

Every repository consuming build-test-sonar@main was getting no SonarCloud analysis and a permanently red build.

Changes

The fix - SONAR_TOKEN is now set as an environment variable on both scanner steps (the scanner reads it natively), and the property name is migrated to sonar.token:

- name: SonarScanner Begin
  shell: pwsh
  env:
    SONAR_TOKEN: ${{ inputs.sonar-token }}
  run: dotnet sonarscanner begin /k:"..." /o:"..." /d:sonar.token="$env:SONAR_TOKEN" ...

- name: SonarScanner End
  shell: pwsh
  env:
    SONAR_TOKEN: ${{ inputs.sonar-token }}
  run: dotnet sonarscanner end /d:sonar.token="$env:SONAR_TOKEN"

Alongside it:

Fail fast on an empty token. A new Validate SonarCloud Token step is the first step in the action and exits 1 with a ::error:: annotation when the input is blank. GitHub does not enforce required: true for composite-action inputs at runtime, so an empty secret previously sailed straight through into an anonymous analysis. Only the token length is logged, never the value. This is the change that would have made the original bug obvious in minutes.
Stop logging the token. Action Properties printed the token after a Login: label. Registered secrets are masked, but a token supplied through a non-secret path (a vars value, a literal) would have been printed in clear text.
actions/setup-dotnet@v3 to @v6 and actions/setup-java@v4 to @v5 (see Design Decisions).
Removed the dead outputs.random-number block - a leftover from the action template that referenced a non-existent step random-number-generator and always evaluated to an empty string.
Documented the dotnet-version default instead of changing it (see Design Decisions).
build-test-snar-ps/build-test-sonar.ps1 had the same sonar.login problem, plus an undefined $sonarToken variable on its begin line. Both lines now use sonar.token with $env:SONAR_TOKEN. That script is not currently wired to any action.

Design Decisions

shell: pwsh was kept, and the token is referenced as $env:SONAR_TOKEN.
This is the subtle part. A bare $SONAR_TOKEN is bash syntax; under pwsh it is an undefined PowerShell variable that expands to an empty string, which would have reintroduced the exact same anonymous-auth bug in a new form. Verified empirically against pwsh 7.6.3 by passing the argument to a real native process and printing the argument vector it received:

FIXED   /d:sonar.token="$env:SONAR_TOKEN"  ->  [/d:sonar.token=squ_0123456789abcdefghijklmnopqrstuvwxyz42]
BUGGY   /d:sonar.token="$SONAR_TOKEN"      ->  [/d:sonar.token=]

Switching the two steps to shell: bash was the alternative. Rejected: every other step in the action uses pwsh, so it would have made the file inconsistent and changed cross-platform behaviour for a composite action that may run on Windows runners. Keeping pwsh is the smaller, more conservative change.

Both the env var and the /d: property are set. Belt and braces: SONAR_TOKEN is what the scanner engine reads natively (this is the difference the issue's evidence isolated), and sonar.token is the correct modern property name. Passing the secret via env: rather than interpolating it directly into run: also follows GitHub's script-injection hardening guidance.

setup-dotnet went to v6, not the v4 the issue suggested. v4 is itself two majors stale and runs on a Node runtime already heading for deprecation, so moving to v4 would have re-created the very deprecation warning this change is meant to clear. Checked the release notes for each intervening major: v4 = Node 20 plus a sequential-install fix; v5 = Node 24 plus removal of references to EOL .NET versions (verified via actions/setup-dotnet#647, a docs/tests/installer-script refresh, not a loss of install capability for supported SDKs); v6 = ESM migration and dependency bumps with no functional breaking change. Same reasoning for setup-java@v5 (Node 24 plus bug fixes; this action pins distribution: zulu and java-version: 17, so upstream default changes do not apply).

The dotnet-version default was deliberately not changed. It stays at 9.0.x. Changing a shared default ships instantly to every consumer at @main and would silently shift SDK selection under repositories that are currently fine. Instead the input description now documents the behaviour and tells consumers targeting net10.0 to set it explicitly, rather than relying on whichever SDK the runner image happens to ship. Zero behaviour change. (The description originally also offered global.json as an alternative; CodeRabbit correctly pointed out that actions/setup-dotnet never falls back to global.json while dotnet-version is supplied, so that half was removed in bc2af89.)

SHA-pinning was left out. None of the uses: references are pinned to commit SHAs, which SonarCloud flags as githubactions:S7637; Amadevus/pwsh-script@v2 in test-script-action is the genuinely third-party one. Left out here to keep this change minimal, and because pinning without Dependabot just trades one problem for another. Filed as #2.

Testing

Verified:

All four action.yml / workflow files in the repository parse as valid YAML (PyYAML safe_load); build-test-sonar yields the expected 11 steps.
Every step referencing SONAR_TOKEN was programmatically cross-checked to confirm it declares shell: pwsh, declares the env: block, uses $env: syntax, and contains no bare $SONAR_TOKEN. All consistent.
Argument expansion tested against pwsh 7.6.3 by invoking a real native executable and printing the argument vector it received - the fixed form passes the token intact, the bash-style form passes an empty value (table above).
The Validate SonarCloud Token step body executed under pwsh across four cases: unset gives exit 1, empty string gives exit 1, whitespace-only gives exit 1, valid token gives exit 0 printing only the length. The token value is never echoed.
grep confirms no sonar.login remains anywhere in the repository.

Reasoned but not executed - a composite action cannot be fully integration-tested without a consuming build, and this repository has no CI workflow that exercises build-test-sonar (run-test-action.yml is workflow_dispatch only and runs test-script-action):

That dotnet sonarscanner begin/end accepts /d:sonar.token and reads SONAR_TOKEN natively. Taken from the issue's evidence, where an inline workflow setting env: SONAR_TOKEN passed against the same project key, organisation and token minutes after this action failed.
That setup-dotnet@v6 and setup-java@v5 behave as documented on the runner images. Assessed from release notes only.

The real end-to-end proof is the next consuming build. ploch-common is inline and unaffected; ploch-commandline has replaced this action with an inline workflow (mrploch/ploch-commandline#17) and was deliberately not touched here.

Breaking Changes

actions/setup-dotnet@v6 and actions/setup-java@v5 run on the Node 24 runtime and require a runner at v2.327.1 or newer. GitHub-hosted runners satisfy this automatically; any self-hosted runner must be updated.
The random-number output is no longer declared. It always evaluated to an empty string and referenced a step that does not exist, so no working consumer can depend on it.

No input names, defaults or required-ness changed, so existing with: blocks continue to work untouched.

Review round 1 (commit `bc2af89`)

Three threads were raised on d56735a; all three have an on-thread reply and are resolved.

Source	Finding	Outcome
CodeRabbit	The `dotnet-version` description wrongly implied `global.json` is a fallback	Fixed. Because the input carries a default it is always passed to `actions/setup-dotnet`, which therefore never falls back to `global.json`. Description reworded to say so. Declined the accompanying suggestions to make the input required (breaks every consumer at `@main`) and to add a `global-json-file` passthrough (speculative new API surface).
CodeAnt	`build-test-sonar.ps1` runs the scanner anonymously when `SONAR_TOKEN` is unset	Fixed. Added the same empty-token guard the composite action now carries. Verified under pwsh 7.6.3: unset, empty and whitespace-only all exit 1; a valid token exits 0 and proceeds.
CodeAnt	PowerShell does not fail fast on native non-zero exits in that script	Declined, with reasoning. Correct as an observation, but pre-existing and not introduced here. The suggested blanket fail-fast would break the first two lines, since `dotnet tool install --global` exits non-zero when the tool is already installed. A correct fix needs per-command `$LASTEXITCODE` handling in a script that is currently dead code. Rolled into #2, which already asks whether these scaffolds should be updated or deleted.

bc2af89 itself was not independently re-reviewed: CodeRabbit reported Review rate limited and states it does not re-review already-reviewed commits, and CodeAnt did not re-trigger. A fresh review was explicitly requested and refused by the service. That commit is a documentation reword plus a four-line guard in an unwired script, both verified locally as described above.

The action supplied the SonarCloud credential only as the sonar.login analysis property. sonar.login was deprecated in favour of sonar.token and is no longer honoured by the current SonarScanner engine, so the scanner authenticated anonymously and post-processing failed at "Create analysis" with a misleading "Not authorized or project not found". Because the token was interpolated successfully, this failed silently rather than erroring on a missing input. Set SONAR_TOKEN as an environment variable on the begin and end steps, which the scanner reads natively, and migrate the property name to sonar.token. Both steps keep shell: pwsh, so the value is referenced as $env:SONAR_TOKEN; a bare $SONAR_TOKEN is bash syntax and would expand to an empty string under pwsh, reintroducing the same anonymous-auth bug in a new form. Also: - Add a Validate SonarCloud Token step that fails fast with a workflow error annotation when the input is empty, instead of proceeding anonymously. GitHub does not enforce required: true for composite action inputs at runtime, so an empty secret previously sailed through. Only the token length is logged, never the value. - Stop writing the token into the Action Properties log line. Registered secrets are masked, but a token supplied through a non-secret path would have been printed in clear text. - Update actions/setup-dotnet v3 to v6 and actions/setup-java v4 to v5. v4 of setup-dotnet was also stale and still runs on a Node runtime heading for deprecation, so it would have re-created the warning this change is meant to clear. - Remove the dead outputs.random-number block, a leftover from the action template that referenced a non-existent step and always evaluated to an empty string. - Document the dotnet-version default rather than changing it, so no consumer's SDK selection shifts under them. - Apply the same sonar.token migration to build-test-snar-ps/build-test-sonar.ps1, whose begin line also referenced an undefined $sonarToken. That script is not currently wired to any action. BREAKING CHANGE: actions/setup-dotnet v6 and actions/setup-java v5 run on the Node 24 runtime and require a runner at v2.327.1 or newer. GitHub-hosted runners satisfy this automatically; self-hosted runners must be updated. The unused random-number output is also no longer declared. Refs: #1

📝 Walkthrough

Walkthrough

The changes update SonarScanner authentication to use sonar.token with SONAR_TOKEN, validate the token before execution, update setup actions, expand SDK input guidance, and remove the obsolete output.

Changes

SonarScanner authentication

Layer / File(s)	Summary
Action validation and setup `build-test-sonar/action.yml`	The action documents SDK selection, rejects a blank `sonar-token`, avoids logging the token, and upgrades the Java and .NET setup actions.
Scanner authentication migration `build-test-sonar/action.yml`, `build-test-snar-ps/build-test-sonar.ps1`	Scanner begin and end commands use `sonar.token` with `SONAR_TOKEN`. Build, test, and coverage sequencing remains unchanged.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to d5673

The change restores authenticated SonarCloud analysis, fails clearly when credentials are missing, and prevents token exposure in logs. It is mergeable with explicit owner awareness that the global.json guidance may mislead consumers and that self-hosted runners must meet the newer runner-version requirement for the updated setup actions.

Included review availability: Your plan provides up to 1 included review per hour; 0 remain after this review.

Address review findings on PR #3. Because dotnet-version carries a default, the action always passes it to actions/setup-dotnet, which therefore never falls back to a global.json in the consuming repository. The input description said consumers could "commit a global.json" as an alternative to setting the input, which is wrong. Reword it to state plainly that the value is always passed and must be set explicitly for other target frameworks. The default is unchanged at 9.0.x, and the input stays optional, so no consumer's SDK selection shifts. Add the same empty-token guard to build-test-snar-ps/build-test-sonar.ps1 that the composite action now has. Without it the script expanded an empty token and ran the scanner anonymously, failing later with the same misleading authorisation error this branch exists to fix. Refs: #1
