Ecore model, graph nodes, and processors for Maven - module, organization, developer, ... Link to a Java module
Use Maven Model as a guide to create the Ecore model and to load the model from XML. https://maven.apache.org/archives/maven-1.x/reference/maven-model/3.0.2/apidocs/org/apache/maven/project/io/xpp3/MavenXpp3Reader.html
Introduce Coordinates base class - not in the Maven model.
May use https://maven.apache.org/ref/3.6.0/maven-resolver-provider/ to build effective pom - https://github.com/indrabasak/stackoverflow-indra/blob/master/effective-pom/src/main/java/com/basaki/EffectivePomBuilder.java
Use cases:
- Local Maven files - scan, generate dependencies report
- Integrate with the GitLab model - scan multiple repositories, load
pom.xml's, establish relationships between repositories, developers, organizations, repositories, ... Generate an HTML site - Same as above plus cross-link with organization-specific entities such as an org/people hierarchy. Loading with creation of sub-classes of model classes. E.g. a subclass of
Developerwith a bi-directional reference to a person in the people hierarchy - this way it will be possible to retrieve a list of Maven projects where a person listed as a developer from a Person object. It will also be possible to roll up this information along the hierarchy and get a list of all Maven projects for a particular organization. Developer role may be linked to a documentation for the role - playbooks etc. - Automated governance:
- Dependencies (especially internal)
- Data quality:
- Presence of, say, description, developers, organization sections in the pom file.
- Cross-referencing. E.g. developers in
pom.xmlshall also be in the CODEOWNERS file.
- Maven URI scheme, e.g.
mavenand URIHandler. URI format:<scheme>://<groupId>/<artifactId>/<version>/<file>[!/<jar path>]. This would allow to transparently load resources from Maven repositories.
https://github.com/yahro/maven-classloader/blob/master/src/main/java/com/bigfatgun/MavenClassLoader.java is an old example of creating a classloader from Maven coordinates. A similar logic may be implemented in Coordinates (GAV).createClassLoader() operation.
