Full Changelog: https://github.com/augi/gradle-docker-java/compare/3.1.0...3.1.1

The baseImage doesn't have to be set if customDockerfile is speficied.

The automatic base image selection feature has been removed. This means the following changes in the API:

• baseImage is required
• javaVersion removed
• windowsBaseImageSpecifier removed

The reason for this change is that choosing the appropriate base image is important and hard, it depends on context, security concerns, etc. Because of this, the base image should be chosen explicitly.

https://github.com/opencontainers/image-spec/blob/main/annotations.md

-XX:+UnlockExperimentalVMOptions -XX:+UseCGroupMemoryLimitForHeap was automatically added to JAVA_OPTS even if a custom base image was specified (and so we couldn't be sure what the Java version is).

As TravisCI changed default groovy environment, recent releases required Java 11 for plugin runtime. Starting with this release, the plugin explicitly targets Java 1.8.

This is a feature inspired by jib.
The plugin now copies dependencies first, and then the application JAR. It means that if there is just change in the application code, the layer with dependencies remains the same, so it hasn't to be pushed, and also hasn't to be downloaded in runtime environment. So it saves both space and bandwidth.

Also Gradle updated from 5.4.1 to 5.6.4.
