fix(lint): make the analyzer settings file the single source - #54
Conversation
PowerShellBuild's default SettingsPath resolves inside its own module directory, so PSScriptAnalyzerSettings.psd1 was never read. CI also passed -Settings PSGallery over the source tree while a local build analysed the built module with a third ruleset. Lint now runs through the build in both places.

Pull request overview
This PR aligns PSScriptAnalyzer configuration so it is defined and consumed from a single place in the template, eliminating discrepancies between local ./build.ps1 -Task Analyze runs and CI linting.
Changes:
- Configure PowerShellBuild to use the repo’s
PSScriptAnalyzerSettings.psd1via$PSBPreference.Test.ScriptAnalysis.SettingsPath. - Update CI linting to run analysis through
./build.ps1 -Task Analyze(instead of callingInvoke-ScriptAnalyzerdirectly), ensuring CI and local runs use the same analyzer settings and target.

IncludeRules = @('*') is a no-op: measured identical findings with and
without it, including on the settings file that enables the formatting
rules, where Enable = $true in the Rules block is what makes them run.
Microsoft's documented settings example omits it entirely.Naming Severity without ParseError hides syntax-broken files entirely:
a file with a missing brace reports zero findings under
@('Error','Warning'). Microsoft documents this as the way to suppress
parse errors, which is the opposite of what a lint gate wants.Uh oh!

What
Two changes so that PSScriptAnalyzer is configured in exactly one place:
build.psake.ps1sets$PSBPreference.Test.ScriptAnalysis.SettingsPathto this repository'sPSScriptAnalyzerSettings.psd1../build.ps1 -Task Analyzeinstead of callingInvoke-ScriptAnalyzerdirectly.Why
PSScriptAnalyzerSettings.psd1was never read. PowerShellBuild's default is:$PSScriptRootthere is PowerShellBuild's own module directory, so the default resolves to the settings bundled with PowerShellBuild. The filename differs from ours too (ScriptAnalyzerSettings.psd1vsPSScriptAnalyzerSettings.psd1), so it could not have matched by accident.That left three rulesets in play:
PSGallerypreset./build.ps1 -Task AnalyzelocallyPSScriptAnalyzerSettings.psd1They also ran over different paths -- CI analysed the source tree, the build analyses the built module. So a local run and CI could disagree with neither being wrong, and the file that looks like the configuration had no effect on either.
The lint job's own comment already stated the goal: it pins the analyzer version "so lint results here match a local
./build.ps1 -Task Analyze". Pinning the version was necessary but not sufficient while the settings and the path still differed.Verification
Removing
PSScriptAnalyzerSettings.psd1now fails the analyze task:Before this change, removing it changed nothing -- which is what "never read" means in practice. With the file present,
./build.ps1 -Task Analyzesucceeds.This repository is behaviour-neutral otherwise: all three rulesets currently report 0 findings against its module source, so nothing new appears. That is deliberate -- it is the safest repository in the fleet to make this change in first.
Scope
This is a pilot. Six sibling repositories have the same problem in varying forms, and one of them (
ScheduledTasksManager) reports 1 finding underPSGalleryagainst 61 under its own settings file, so it needs its findings triaged rather than a mechanical change. Doing them one at a time.No
