• #​24122 Update configuration cache state for some plugins
• #​24129 includeBuild in PluginManagementSpec deincubated in Gradle 8, docs still say it's incubating

Issues fixed in the first patch release:

• #​23888 --no-rebuild suddenly gone without new deprecation cycle and without the reason for its undeprecation being void

vanniktech/gradle-maven-publish-plugin (com.vanniktech.maven.publish)

v0.30.0

Compare Source

• Add support for Dokka 2.0.0-Beta
  • Supports org.jetbrains.dokka.experimental.gradle.pluginMode=V2Enabled
  • Supports both org.jetbrains.dokka and org.jetbrains.dokka-javadoc
  • If both are applied the javadoc output is published
  • Removed support for the old org.jetbrains.dokka-android plugin
• Support custom Sonatype hosts by providing a https url in SONATYPE_HOST Gradle property
• Remove usages of deprecated Gradle API that is scheduled to be removed in Gradle 9.0
• Raised minimum supported Gradle version
• Improve naming of javadoc jars

Minimum supported versions

• JDK 11
• Gradle 8.5
• Android Gradle Plugin 8.0.0
• Kotlin Gradle Plugin 1.9.20

Compatibility tested up to

• JDK 23
• Gradle 8.10.2
• Android Gradle Plugin 8.7.0
• Android Gradle Plugin 8.8.0-alpha05
• Kotlin Gradle Plugin 2.0.20
• Kotlin Gradle Plugin 2.1.0-Beta1

Configuration cache status

Configuration cache is generally supported, except for:

• Publishing releases to Maven Central (snapshots are fine), blocked by Gradle issue #​22779.
• When using Dokka 1.x or Dokka 2.x without V2Enabled

v0.29.0

Compare Source

• Added configureBasedOnAppliedPlugins(sourcesJar: Boolean, javadocJar: Boolean)
  overload that allows disabling sources and javadoc jars without having to use
  the more granular Platform APIs.
• For Java library and Kotlin/JVM projects the Gradle module metadata now properly
  includes the sources jar.
• When running on Gradle 8.8 or newer the pom configuration is not applied in
  afterEvaluate anymore, making manual overrides easier.
• Fix potential issue with the javadoc jar tasks that can cause Gradle to disable
  optimizations.
• When staging profiles can't be loaded the status code of the response is added
  to the error message.

Minimum supported versions

• JDK 11
• Gradle 8.1
• Android Gradle Plugin 8.0.0
• Kotlin Gradle Plugin 1.9.20

Configuration cache status

Configuration cache is generally supported, except for:

• Publishing releases to Maven Central (snapshots are fine), blocked by Gradle issue #​22779.
• Dokka does not support configuration cache

v0.28.0

Compare Source

• Added support for publishing through the new Central Portal. To use
  this use the CENTRAL_PORTAL option when specifying the Sonatype host.
• For Kotlin Multiplatform the main plugin will now automatically publish the
  release variant if the project has an Android target and no variant was explicitly
  specified through the Kotlin Gradle DSL.
• Support specifying the Android variants to publish in KotlinMultiplatform(...).
• Updated minimum supported Gradle, Android Gradle Plugin and Kotlin versions.
• Removed support for the deprecated Kotlin/JS plugin.
• Removed the deprecated closeAndReleaseRepository task. Use releaseRepository, which
  is functionally equivalent, instead.

Minimum supported versions

• JDK 11
• Gradle 8.1
• Android Gradle Plugin 8.0.0
• Kotlin Gradle Plugin 1.9.20

Compatibility tested up to

Configuration cache status

Configuration cache is generally supported, except for:

• Publishing releases to Maven Central (snapshots are fine), blocked by Gradle issue #​22779.
• Dokka does not support configuration cache

v0.27.0

Compare Source

• Added new publishing related tasks
  • releaseRepository releases a staging repository at the end of the build
    and can be executed in the same build as the publishing task. This allows
    having automatic releases without permanently enabling them.
  • publishToMavenCentral as alias for running publishAllPublicationsToMavenCentralRepository.
  • publishAndReleaseToMavenCentral as alias for running both of the above.
  • For more information checkout the docs.
• It is now possible to only pass a subset of the parameters to
  coordinates(...) and leave the others at their default value.
  Thanks to @​sschuberth for the contribution.
• Fixed java-test-fixture projects being broken with Gradle 8.6.
• Deprecated closeAndReleaseRepository in favor of releaseRepository.

When using Gradle 8.1 or newer configuration cache is generally supported.

Exceptions to that are:

• Dokka does not support configuration cache

v0.26.0

Compare Source

• It's now supported to call configure(Platform) from the main plugin to modify
  what is getting published. Check out the docs for more details
• The base plugin now has a configureBasedOnAppliedPlugins DSL method to
  allow applying the default configure logic of the main plugin.
• Calling configure(Platform) now validates that the required plugins are
  applied (e.g. Android Gradle Plugin for Android projects).
• It's now possible to disable source publishing for KMP projects.
• Fixed an issue which would cause the javadoc jar task to be registered multiple
  times for Gradle plugin projects with more than one publication. Thanks to
  @​autonomousapps for the fix.
• Publishing Kotlin/JS projects has been deprecated and will be removed in the
  next release, because the Kotlin/JS plugin has been deprecated.
• The internal task to create a javadoc jar for certain project types has been renamed
  from simpleJavadocJar to plainJavadocJar. Thanks to @​sschuberth.
