jib-maven-plugin

Major Changes

• <to><credHelper> and <from><credHelper> can be used to specify a credential helper suffix or a full path to a credential helper executable
• Adds <container><user> configuration parameter to configure the user and group to run the container as
• Adds preliminary support for building images for WAR projects
• Adds <extraDirectory> object with a path and permissions field
  • <extraDirectory><path> configures the extra layer directory (still also configurable via <extraDirectory>...</extraDirectory>)
  • <extraDirectory><permissions> is a map from absolute path on container to the file's permission bits (represented as an octal string)
• Image digest is now written to target/jib-image.digest
• Adds the layer type to the layer history as comments
• Removes deprecated <jvmFlags>, <mainClass>, <args>, and <format> in favor of the equivalents under <container>
• jib:exportDockerContext generates different directory layout and Dockerfile to enable WAR support
• File timestamps in the built image are set to 1 second since the epoch (hence 1970-01-01T00:00:01Z) to resolve compatibility with applications on Java 6 or below
