8.1.6 Release (2023-07-06)

New Recipes

• org.openrewrite.gradle.spring.AddSpringDependencyManagementPlugin: Add io.spring.dependency-management plugin, if in use.

• org.openrewrite.java.migrate.guava.PreferJavaNioCharsetStandardCharsets: Prefer java.nio.charset.StandardCharsets instead of using com.google.common.base.Charsets.

• org.openrewrite.java.migrate.guava.PreferJavaUtilObjectsRequireNonNull: Prefer java.util.Objects#requireNonNull instead of using com.google.common.base.Preconditions#checkNotNull.

• org.openrewrite.java.migrate.lang.UseVar: Apply local variable type inference (var) for primitives and objects.

• org.openrewrite.java.migrate.lang.var.UseVarForObject: Try to apply local variable type inference var to variables containing Objects where possible. This recipe will not touch variable declarations with generics or initializers containing ternary operators.

• org.openrewrite.java.migrate.lang.var.UseVarForPrimitive: Try to apply local variable type inference var to primitive variables where possible. This recipe will not touch variable declarations with initializers containing ternary operators.

• org.openrewrite.java.migrate.util.RemoveFinalizerFromZip: Remove invocations of finalize() deprecated invocations from Deflater, Inflater, ZipFile.

• org.openrewrite.java.testing.hamcrest.AssertThatBooleanToAssertJ: Replace Hamcrest assertThat(String, boolean) with AssertJ assertThat(boolean).as(String).isTrue().

• org.openrewrite.java.testing.hamcrest.HamcrestMatcherToAssertJ: Migrate from Hamcrest Matcher to AssertJ assertions.

• org.openrewrite.java.testing.hamcrest.HamcrestNotMatcherToAssertJ: Migrate from Hamcrest not(Matcher) to AssertJ assertions.

• org.openrewrite.java.testing.hamcrest.MigrateHamcrestToAssertJ: Migrate Hamcrest assertThat(..) to AssertJ Assertions.

• org.openrewrite.java.testing.hamcrest.RemoveIsMatcher: Remove Hamcrest is(Matcher) ahead of migration.

• org.openrewrite.kotlin.cleanup.EqualsMethodUsage: In Kotlin, == means structural equality and != structural inequality and both map to the left-side term’s equals() function. It is, therefore, redundant to call equals() as a function. Also, == and != are more general than equals() and !equals() because it allows either of both operands to be null. Developers using equals() instead of == or != is often the result of adapting styles from other languages like Java, where == means reference equality and != means reference inequality. The == and != operators are a more concise and elegant way to test structural equality than calling a function.

• org.openrewrite.kotlin.cleanup.ImplicitParameterInLambda: "it" is a special identifier that allows you to refer to the current parameter being passed to a lambda expression without explicitly naming the parameter.Lambda expressions are a concise way of writing anonymous functions. Many lambda expressions have only one parameter, when this is true the compiler can determine the parameter type by context. Thus when using it with single parameter lambda expressions, you do not need to declare the type.

• org.openrewrite.kotlin.cleanup.ReplaceCharToIntWithCode: Replace the usage of the deprecated Char#toInt() with Char#code. Please ensure that your Kotlin version is 1.5 or later to support the Char#code property. Note that the current implementation does not perform a Kotlin version check.

• org.openrewrite.maven.UpdateMavenWrapper: Update the version of Maven used in an existing Maven wrapper.

• org.openrewrite.staticanalysis.EqualsToContentEquals: Use String.contentEquals(CharSequence) instead of String.equals(CharSequence.toString()).

• org.openrewrite.staticanalysis.RemoveHashCodeCallsFromArrayInstances: Replace hashCode() calls on arrays with Arrays.hashCode() because the results from hashCode() are not helpful.

• org.openrewrite.staticanalysis.RemoveToStringCallsFromArrayInstances: The result from toString() calls on arrays is largely useless. The output does not actually reflect the contents of the array. Arrays.toString(array) give the contents of the array.

Removed Recipes

• org.openrewrite.java.migrate.hibernate.MigrateToHibernate61: This recipe will apply changes commonly needed when migrating to Hibernate 6.1.x. The hibernate dependencies will be updated to use the new org.hibernate.orm group ID and the recipe will make changes necessary to use Hibernate with Jakarta EE 9.0.

• org.openrewrite.java.migrate.hibernate.MigrateToHibernateDependencies61: This recipe will migrate any existing dependencies on Hibernate 5.x to the latest 6.1.x release. This migration will include the adjustment to the new org.hibernate.orm group ID. It accounts for artifact names that both do and do not include the jakarta suffix and it will change both dependencies and managed dependencies.

• org.openrewrite.java.spring.boot3.MavenPomUpgrade: Upgrade Maven POM to Spring Boot 3.0 from prior 2.x version.

• org.openrewrite.java.spring.boot3.MavenPomUpgrade_3_1: Upgrade Maven POM to Spring Boot 3.1 from prior 3.0 version.

• org.openrewrite.kotlin.StaticAnalysis: Static analysis fixes for Kotlin sources.
