• Added configuration cache support for publishing.
• Removed support for publishing through Sonatype OSSRH since it has been shut down. See the
  0.33.0 release notes for upgrade
  instructions if you haven't upgraded yet.
  • SonatypeHost has been removed from the DSL.
  • SONATYPE_HOST only supports CENTRAL_PORTAL now. It's recommended to use the following properties instead:
    • mavenCentralPublishing=true replaces SONATYPE_HOST=CENTRAL_PORTAL.
    • mavenCentralAutomaticPublishing=true replaces SONATYPE_AUTOMATIC_RELEASE=true.
• Update the Central Portal Publisher APIs to the latest.
• It's now possible to mix SNAPSHOT versions and release versions when running publish tasks.
• Fixed Gradle's deprecation warning caused by invalid URI.
• Fixed check for the minimum supported Gradle version running too late in some cases.

Thanks to @Goooler and @solrudev for their contributions to this release.

Minimum supported versions

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

BREAKING

• publishToMavenCentral() and publishToMavenCentral(automaticRelease) without SonatypeHost will
  now publish through the Central Portal.
• Deprecated overloads of publishToMavenCentral that take a SonatypeHost parameter.
• Deprecated SonatypeHost.

New

• Basic experimental support for com.android.fused-library. There are currently several limitations
  on the Android Gradle plugin side which make signing as well as publishing sources/javadocs not possible.

Improvements

• Added new Gradle properties
  • mavenCentralPublishing=true replaces SONATYPE_HOST=CENTRAL_PORTAL
  • mavenCentralAutomaticPublishing=true replaces SONATYPE_AUTOMATIC_RELEASE=true
  • signAllPublications=true replaces RELEASE_SIGNING_ENABLED=true
  • Note: The old properties continue to work and there are no plans to remove them
• The base plugin is now compatible with isolated projects as long as pomFromGradleProperties() is
  not called.
• It's possible to pass a TaskProvider to JavadocJar.Dokka
• Improved naming of produced -javadoc jars (locally, the name of the published artifact is unchanged)
• Resolve issue that caused version to be read too early when publishing to
  Central Portal.

  times for Gradle plugin projects with more than one publication. Thanks to
  @autonomousapps for the fix.
