ArchUnit 1.0.0-rc1

Breaking Changes

• All deprecated members and classes have been removed (see #909)
• @AnalyzeClasses() without any explicit locations to import will now import the package of the annotated class by default instead of the whole classpath. To restore the old behavior use @AnalyzeClasses(wholeClasspath = true) (see #828)
• The archunit-junit5-engine-api now resides within the package com.tngtech.archunit.junit.engine_api instead of directly under junit. This only affects users that want to programmatically interface with the ArchUnitTestEngine and should be irrelevant for most users (see #827)
• ArchUnit now needs at least Java 8 to run (see #833)
• The ArchUnit types Function, Predicate and Optional have been replaced by the JDK 8 equivalents
• DescribedPredicate now extends the JDK 8 Predicate, so apply(..) has to be replaced by test(..)
• layeredArchitecture() now forces to decide how to deal with dependencies by adding .considering...Dependencies() in the beginning of the declaration. To restore the old behavior declare it as layeredArchitecture().consideringAllDependencies() (see #892)
• ConditionEvents is now an interface and the interface has been cleaned out of all non-essential methods, e.g. getAllowed(). This was done to increase maintainability and make it easier to optimize the internals. If you are missing any functionality now, please file an issue to discuss it (see #876)
• PackageMatcher was moved from package base to core.domain (see #894)
• Primitive classes now reside in package java.lang to be consistent with the Reflection API's Class.getPackageName() (see #905)
• PlantUmlArchCondition.Configurations has been merged into PlantUmlArchCondition.Configuration (see #891)

Bug Fixes

• While technically no real bug PlantUmlArchCondition.Configuration is now a public class instead of an interface, which solves a (non-fatal) Kotlin compiler warning complaining about the access rights (see #888)

Enhancements

Core

• Accesses from inside of lambdas are now correctly detected. Before, the origin was set as a synthetic method like lambda$xxx$123 instead. JavaAccess can now be queried for isDeclaredInLambda() to distinguish this from an access outside of a lambda (see #847; thanks a lot to @oberprah, @FrederikFinckh)
• Support for Java 19 (see #845)
• It is now possible to analyze try-catch-blocks, e.g. if a method call is wrapped into a try-catch-block catching a certain exception type (see #591; thanks a lot to @crizzis)
• Package identifiers like ..myapp.service.. now support alternations via ..[service|legacy_service]... This also works for capturing groups like (a|b). Note that alternation groups cannot be nested (see #662; thanks a lot to @Pfoerd)
• DescribedPredicate now offers static factory methods and(predicates) and or(predicates) that join together varargs DescribedPredicate<>... or Iterable<DescribedPredicate<>> via AND or OR (see #805)
• The importer now ignores synthetic $SwitchMap$ fields of enums (see #570)
• Private member accesses are now correctly reported between inner classes. Before, the origin was set as a synthetic method access$123 (see #889)
• ImportOption.DoNotIncludeTests now works for plain IntelliJ project layouts (see #696; thanks a lot to @JCook21)

Lang

• New methods codeUnits().should().onlyBeCalled().by{Classes/Methods/...}That(..) (see #810; thanks a lot to @JKLedzion)
• ArchCondition evaluation is now more efficient and has a smaller memory footprint (see #876)
• The ArchCondition to search for transitive dependencies has been improved and now only reports relevant dependencies, in particular when checking for transitive dependencies between packages a and b (see #780; thanks a lot to @Pfoerd)
• New APIs ArchCondition.from(predicate) and ArchConditions.{be/have}(predicate) to easily create ArchConditions from DescribedPredicates (see #855; thanks a lot to @u3r)
• Javadoc of the rules API has been extended to better guide to predefined DescribedPredicates like JavaClass.Predicates or HasName.Predicates (see #912)
• New convenience method ConditionEvent.createMessage(..) to easily create a standard ArchRule violation message like Class <..> some description in (...java:123) (see #826)

Library

• layeredArchitecture() now allows to easily specify how to deal with dependencies from classes within the layers. E.g. should only dependencies that target other classes within the layers be considered? Or all dependencies in the root package of the application? This should solve common confusion about dependencies on classes like java.lang.Object being reported (see #887)
• onionArchitecture() components can now not only be defined by package identifiers but also by predicates (see #894)
• layeredArchitecture() and onionArchitecture() now support ensureAllClassesAreContainedInArchitecture() (see #278; thanks a lot to @roxspring)
• New rule GeneralCodingRules.testClassesShouldResideInTheSamePackageAsImplementation() to check that test classes reside in the same package as their class under test (see #475; thanks a lot to @mslowiak)

JUnit

• The archunit-junit5 can now be used on the modulepath as well as the classpath (see #206)
• JUnit 5 discovery speed is now notably faster in test projects with a lot of dependencies (see #546)
• For JUnit 5 support @ArchTest is now also supported within abstract base classes (see #104; thanks a lot to @hankem)
