Major Changes

• Allow setting platform when building image from scratch. (#2765)
• New system property jib.skipExistingImages (default = false) to skip pushing images (manifests) if the image already exists in the registry. (#2360)
• (Incubating) can now configure multiple platforms (such as architectures) to build multiple images as a bundle and push as a manifest list. (#2523, #1567)
• Upgraded the ASM library to 9.0 to resolve an issue when auto-inferring main class in Java 15+. (#2776)
• Fixed NullPointerException when the "auths": section in ~/.docker/config.json has an entry with no "auth": field. (#2535)
• Fixed NullPointerException to return a helpful message when a server does not provide any message in certain error cases (400 Bad Request, 404 Not Found, and 405 Method Not Allowed). (#2532)
• Now supports sending client certificate (for example, via the javax.net.ssl.keyStore and javax.net.ssl.keyStorePassword system properties) and thus enabling mutual TLS authentication. (#2585, #2226)
• Fixed NullPointerException during input validation (in Java 9+) when configuring Jib parameters using certain immutable collections (such as List.of()). (#2702)
• Fixed authentication failure with Azure Container Registry when using "tokens". (#2784)
• Improved authentication flow for base image registry. (#2134)

jib-maven-plugin

Major Changes

• Fixed the regression introduced in 2.5.1 that caused Jib to containerize a Spring Boot fat JAR instead of a normal thin JAR when <containerizingMode>packaged is set and the Spring Boot Maven plugin does not have a <configuration> block. (#2693)

See CHANGELOG.md for more details.

jib-maven-plugin

Major Changes

• Incubating feature: can now configure desired platform (architecture and OS) to select the matching manifest from a Docker manifest list for a base image. Currently supports building only one image. OCI image indices are not supported. (#1567)

    <from>
      <image>... image reference to a manifest list ...</image>
      <platforms>
        <platform>
          <architecture>arm64</architecture>
          <os>linux</os>
        </platform>
      </platforms>
    </from>

• Now supports sending client certificate (for example, via the javax.net.ssl.keyStore and javax.net.ssl.keyStorePassword system properties) and thus enabling mutual TLS authentication. (#2585, #2226)
• Fixed reporting a wrong credential helper name when the helper does not exist on Windows. (#2527)
• Also tries .exe file extension for credential helpers on Windows. (#2527)
• Fixed NullPointerException when the "auths": section in ~/.docker/config.json has an entry with no "auth": field. (#2535)
• New system property jib.skipExistingImages (false by default) to skip pushing images (manifests) if the image already exists in the registry. (#2360)
• Fixed an issue where Jib cannot infer Kotlin main class that takes no arguments. (#2666)
• Fixed build failure with <containerizingMode>packaged in Spring Boot projects where Jib assumed a wrong JAR path when <finalName> or <classifier> is configured in Spring Boot. (#2565)

See CHANGELOG.md for more details.
