The deprecated Groovy syntax relies on the property-setter fallback and never resolves to a declared method. A call that does, such as `matcher.group(1)` in a build script, was rewritten to `matcher.group = 1`, which fails to evaluate.

UsePropertyAssignmentSyntaxnow leaves a call alone when it resolves to a declared method. The deprecated Groovy syntax (group 'x',project.version '1') only works through the property-setter fallback, so it never has a method type. Added a no-op test forMatcher.group(int)withpropertyName: group.What's your motivation?
With
propertyName: group(part ofUseAssignmentForPropertySyntax/MigrateToGradle8), any single-argument call namedgroupwas converted, including regular method calls in build script logic:def m = java.util.regex.Pattern.compile("(\\d+\\.\\d+\\.\\d+).*").matcher(version.toString()) if (m.find()) { - milestoneLabel = m.group(1) + milestoneLabel = m.group = 1 }Gradle then fails to evaluate the script:
No such property: group for class: java.util.regex.Matcher. Seen in LogNet/grpc-spring-boot-starter.
