devc goal

This release includes the general availability of the new devc goal for Liberty Dev mode to start the server in a Docker container. Refer to the docs for the devc goal for more information.

The following fixes related to the dev and devc goals are included in this release since the previous milestone release.

Startup changes:

• Skip installing local runtime when starting devc
• Auto-resolve port conflicts on devc startup
• Pull the latest parent image specified in the Dockerfile during devc startup
• Check for supported Docker version on devc startup
• Disabled OpenJ9 SCC when devc builds docker image
• The dev and devc startup message format was improved and now devc startup displays:
  -- internal container ports and mapped host ports
  -- container name, IP address, and connected Docker network

Updated messaging:

• Changed Docker port mapping errors to warnings
• Added an error message when incompatible Java versions are used between the host and container.
• Display warning when users attempt to install features not included with the beta runtime
• Fixed an issue where a docker stop error was shown when the container failed to start

File tracking changes:

• Track Dockerfile changes and rebuild image on changes
• Track folders specified in Dockerfile COPY commands and rebuild image on changes
• Track folders and files specified in Dockerfile ADD commands and rebuild image on changes

Other fixes:

• Changed dev mode's container naming convention to use hyphens instead of underscores
• Let user provided container name override dev mode default container name
• Fixed an issue where dev mode was not using Maven compiler options for recompiles 
• Fixed an issue with auto-resolving port conflicts on Windows
• Added an option to keep the temporary Dockerfile that dev mode uses to build the Docker image

copyDependencies parameter

This release includes the general availability of the new copyDependencies parameter for copying dependencies during server creation. If a dependency is not listed in the Maven dependencies section of the pom.xml, then the full GAV coordinates will need to be specified in the copyDependencies configuration. Alternatively, you can copy all resolved dependencies matching a specific groupId, or a specific groupId and artifactId. The artifactId may also end with a * to match all artifacts that have an artifactId that start with the specified string. Transitive dependencies are also copied. Additionally, a stripVersion parameter is available to strip the version during the copy. Refer to the common server parameters documentation for more information.

Additional Fixes

The following additional fixes are also included in this release since the previous milestone release.

• Fixed resolution of Liberty directory properties in the location attribute of the include element in the server.xml file
• Removed warning message for redundant configuration files
• Resolve plugins from PluginManagement if not resolved on the Project
