Nebula ArchRules

This repository contains several libraries of ArchRules which can be used in projects by using the ArchRules Runner plugin.

Deprecation Rules

Joda Rules

These rules enforce the usage of java.time over Joda Time

Testing Frameworks Rules

These rules enforce upgrading to JUnit Jupiter

Nullability Rules

These rules enforce JSpecify nullability annotations on public code. Kotlin classes are exempt from the rule, as Kotlin has nullability built into its type system, which is compatible with JSpecify.
