This commit migrates ProjectDescription to an interface with read-only
accessors and create a MutableProjectDescription implementation that can
be used for both purposes.
As a result, the type separation between ResolvedProjectDescription and
ProjectDescription is no longer necessary.
Closes gh-993
This commit moves project-based assertions to regular AssertJ Assert
classes. `ProjectStructure` is now an assert provider so that it can
be used with the standard `assertThat` method.
Specialized assertions are provided for the supported build systems as
well as text-based content.
Closes gh-764
This commit extracts various test utilities to a dedicated
initializr-generator-test module for easier consumption. The previous
test-jar are no longer published and a dependency to this new module
should be equivalent.
This commit also cleans various resources that were located in the wrong
place. In particular initializr-generator does not know anything about
metadata anymore.
Closes gh-988
