configurationPropertiesPrefixKebabCase: false positive when prefix uses a const val template

[yluom]

Summary

The configurationPropertiesPrefixKebabCase rule validates the raw string literal passed to @ConfigurationProperties without resolving Kotlin const val references. Prefixes built with string templates referencing top-level constants are flagged even though the runtime value is valid kebab-case.

Reproducer

const val APP_CONFIG_ROOT = "myapp"

@ConfigurationProperties("\$APP_CONFIG_ROOT.foo")
data class FooProperties(val bar: String)

Running springBootRules { all() }.verify() reports:

CodeGuard:configurationPropertiesPrefixKebabCase: @ConfigurationProperties prefix should use lowercase kebab-case segments:
FooProperties has prefix '\$APP_CONFIG_ROOT.foo'

The effective prefix at runtime is myapp.foo, which is valid kebab-case.

Environment

• spring-boot-code-guard 1.0.7
• Kotlin 2.3
• Konsist 0.17.3

Expected

Either:

1. Resolve the const val reference before validating, or
2. Skip validation when the prefix contains an unresolved template expression (avoid false positives), or
3. Document the limitation explicitly.

Thanks for the report. I'll check the possibility of resolving const val, but there may be limitations with the Konsist library.

[NordCoderd]

New version 1.0.8 has been published with the fix of the problem, and it should be fine for now.
