Function resolveVersionOverride

pkg/toolinstall/versionoverride.go:19–36

resolveVersionOverride returns a package view for a specific version with the first matching aqua "version_override" applied. Packages without version_overrides are returned unchanged. aqua evaluates the base package's own constraint first (commonly "false" so it never matches on its own), then eac

(pkg *Package, version string)

// it never matches on its own), then each override top-to-bottom; the first
// match wins and its fields are layered over the base.

// applyVersionOverride layers a matched override's non-empty fields onto a copy
