With the introduction of the build pom and raw -> build pom transformation, the construction of the effective poms in two steps become very problematic. Over the time, multiple caches have been added to the ProjectBuilder and ModelBuilder related classes which are often redundant.
This PR thus changes things and move the recursive construction of the models fully into the ModelBuilder in a single call. When building build poms, a first step is done by parsing the file models from the root, then building all needed effective models from those. All the inference can be cleanly done because the builder has all the file models ready. The result will be used by the ProjectBuilder to build the projects.
* [MNG-7914] Provide a single entry point for configuration
* [MNG-7914] Rename global -> installation
* [MNG-7914] Include time zone in Maven build timestamp
* [MNG-7914] Use a single place to document all maven properties
* Add an InternalSession interface to avoid casting to the implementation in various places
* Upgrade to Guice 6.0.0 and add support for jakarta.inject annotations
* Maven 4 Plugin API
This commit introduces three properties:
* project.rootDirectory: the project's directory or parent directory containing a .mvn subdirectory or a pom.xml flagged with the root="true" attribute. If no such directory can be found, accessing the rootDirectory property will throw an IllegalStateException.
* session.topDirectory : the directory of the topmost project being built, usually the current directory or the directory pointed at by the -f/--file command line argument. The topDirectory is similar to the executionRootDirectory property available on the session, but renamed to make it coherent with the new rootDirectory and to avoid using root in its name. The topDirectory property is computed by the CLI as the directory pointed at by the -f/--file command line argument, or the current directory if there's no such argument.
* session.rootDirectory : the rootDirectory for the topDirectory project.
The topDirectory and rootDirectory properties are made available on the MavenSession / Session and deprecate the executionRootDirectory and multiModuleProjectDirectory properties. The rootDirectory should never change for a given project and is thus made available for profile activation and model interpolation (without the project. prefix, similar to basedir). The goal is also to make the rootDirectory property also available during command line arguments interpolation.
A root boolean attribute is also added to the model to indicate that the project is the root project. This attribute is only supported if the buildconsumer feature is active and removed before the pom is installed or deployed. It can be used as an alternative mechanism to the .mvn directory.
