> For usage of the {{mvn release:prepare}} command in situations where CLI arguments are not possible, I would like to have support for providing the plugin user properties via a properties file.
> An example situation I need it for, is the following:
> CI systems like Jenkins have multiple steps in a single job. Environment variables being only in scope for one single step, making it impossible to have a maven release plugin userProperty created dynamicly and use the CLI args ("-D...") to pass userProperties to maven.
> Specific use case is passing a custom {{releaseVersion}} and {{developmentVersion}}, I noticed for this a nice solution is already on the roadmap under the case MRELEASE-431. But I'm sure this new properties file can be used in more cases.
> As I need this for the release:prepare goal, I currently implemented this only for this goal. I've attached the patch "support.user.properties.patch" with my implementation. I've fitted it in the maven-release-plugin instead of the maven-release-manager as this change is purely about reading configuration that is lateron passed to maven-release-manager APIs.
> Technical details:
> - The properties file to put the user properties in, is currently called 'release.user.properties'
> - Order of reading the user properties is:
> -- First read the properties from the pom (where available)
> -- Merge the read properties with the properties from the release.user.properties
> -- Merge the merged properties with user properties provided the command line arguments
> -- Then call to maven-release-manager API is made, which reads/writes the 'release.properties' file
> - All non-readonly user properties supported by release:prepare are supported
> - All properties from the original release.properties file are supported
> - I only created a unit-test, as I couldn't find out how integration-tests work or where they are located
