Overview

After a long hiatus without releases, this version simplifies the packaging of
Hamcrest into a single jar: hamcrest-2.1.jar. Other big changes include
Java 9 module compatibility, along with numerous other improvements and bug
fixes.

Breaking Changes

• Although the class API has not changed since Hamcrest 1.3, the way that the
  project is packaged has changed. Refer to the Hamcrest Distributables
  documentation for more information, and in particular the section on
  Upgrading from Hamcrest 1.x
• The org.hamcrest.Factory annotation has been removed (it should not be used in client code)

Changes

• Publish a single jar hamcrest-2.1.jar
• Documentation updates
• Add implementation for CharSequence length matcher
• Fix for TypeSafeDiagnosingMatcher can't detect generic types for subclass
• Renamed IsCollectionContaining to IsIterableContaining
• Make Hamcrest an OSGI bundle
• Add StringRegularExpression matcher
• Fix StringContainsInOrder to detect if a repeated pattern is missing
• Add ArrayAsIterableMatcher
• Fix description for IsEqualIgnoringCase
• Fix JavaDoc examples
• Upgraded to Java 7
• Build with Gradle
• Publish a single jar java-hamcrest-2.0.0.0.jar
• Deprecate IsCollectionContaining and IsArrayContainingXXX
• Removed deprecated methods from previous release
• Improve mismatch description of hasItem/hasItems
• General improvements to mismatch descriptions
• Several JavaDoc improvements and corrections
• Deprecated several matcher factory methods of the for "isXyz"
• Fix GH issue #75 - address doclint errors reported in JDK 1.8
• Fix GH issue #69 - Iterable contains in order is null-safe
• Fix GH issue #59 - added equalToObject() (i.e. unchecked) method
• Fix GH issue #25 - arrayContaining(null, null) cause NullPointerException
• Fix GH issue #36 - string matching on regular expressions
• Fix GH issue #8 - isCloseTo() shows wrong delta in mismatch description
• Fix GH issue #59 - add untyped version of equalTo, named equalToObject
• Fix GC issue #131 - Implement IsEmptyMap, IsMapWithSize
• Fix GC issue #187 - IsArray.describeMismatchSafely() should use Matcher.describeMismatch
• Fix GC issue #155 - Add Matcher implementation for files
• Fix GC issue #69 - fix NPE in IsIterableContainingInOrder

Restore deleted classes to keep backwards compatibility with version 1.3, and mark them as deprecated.

This fixes the problem that Maven has with interpreting pom-only artifacts. Both hamcrest-core and hamcrest-library artifacts now publish empty jars with a dependency on the hamcrest artifact.

This release publishes pom-only artifacts for hamcrest-core and hamcrest-library for better backwards compatibility with previous releases.

• Introduce Condition class to ease the implementation of multi-step matches
• Upgrade qdox (included in the generator) to the latest stable version
• Correct inadvertent deprecation of the Is.isA factory method
• Fix issue #179 - AllOf does not output mismatch description
• Fix issue #177 - Introduced closeTo matcher for BigDecimals
• Fix issue #152 - Factory classes missing from matchers.xml
• Fix issue #144 - OrderingComparison doesn't describe mismatch of comparables that return values other than (-1,0,1)
• Fix issue #134 - DescribedAs does not delegate describeMismatch
• Fix issue #106 - deprecation warning when writing custom matchers
• Fix issue #101 - Added theInstance alias for sameInstance factory method

• Added mismatch reporting
• Added WithSamePropertyValuesAs matcher
• Moved any() from IsAnything to IsInstanceOf. It now checks the type of the matched object
• Moved MatcherAssert from integration to core
• Tightened up generics.
• Added IsMapContainingKey and IsMapContainingValue matchers to resolve a generics bug in hasKey and hasValue static factories previously declared in IsMapContaining (ngd)
• Added IsCollectionOnlyContaining and IsArrayOnlyContaining which matches collections (and arrays) where all match a given matcher. E.g onlyContains(3,4,5) or onlyContains(lessThan(9))
• text module moved to separate project, hamcrest-text-patterns
• added more colection matchers: xContainingInAnyOrder, xContainingInOrder, xWithSize
• new text Matcher: IsEmptyString
• hamcrest generator uses method return type

• Hamcrest Generator now includes JavaDoc and parameter names in generated code by using QDox to parse the source code.
• Created hamcrest-core.jar (and removed hamcrest-api.jar). Moved core set of matchers (and, eq, not, etc) to this package to make it more practical for external libraries to embed Hamcrest.
• Created CoreMatchers (static import sugar) in hamcrest-core.jar.
• StringBuilder can use any Appendable (not just StringBuffer).
• Added sensible toString() method to BaseMatcher.
• Created StringDescription.asString() alias (because toString() caused issues with static imports).
• Relaxed isInstanceOf() matcher generic type so it can be used on any kind of object. e.g. assertThat(someUnknownObject, isInstanceOf(String.class));
• Added any(Class<T>), null(Class<T>) and notNull(Class<T>) matchers, which returns Matcher<T>. Helpful when the compiler struggles with type inference.
• Modified anyOf() and allOf() to accept mixed-types.
• TypeSafeMatcher.matchesSafely() is now public.
• Generator recognizes @Factory methods that return subclass of Matcher. (Fix by David Saff)

Initial release.

• Support for namespaces in HasXPath
• Bug fix for matching empty elements with HasXPath
