in repository https://gitbox.apache.org/repos/asf/maven.git
commit 0e1faeac63e0eb6704e62ec7cac3dc58ed03a518
Author: Guillaume Nodet <gno...@gmail.com>
AuthorDate: Tue Oct 7 16:54:26 2025 +0200
Allow repository URL interpolation with improved validation (#11140)
This commit enables repository URL interpolation in Maven 4 while
maintaining
backward compatibility and providing early validation of unresolved
expressions.
Repository URLs can now use expressions like ${env.REPO_URL} and
${project.basedir.uri}
which are interpolated during model building.
Key changes:
1. DefaultModelBuilder: Add repository URL interpolation during model
building
- Support for repositories, pluginRepositories, profiles, and
distributionManagement
- Provide basedir, project.basedir, project.basedir.uri,
project.rootDirectory,
and project.rootDirectory.uri properties for interpolation
- Enable environment variable and project property interpolation in
repository URLs
2. DefaultModelValidator: Validate interpolated repository URLs for
unresolved expressions
- Repository URL expressions are interpolated during model building
- After interpolation, any remaining ${...} expressions cause validation
errors
- Early failure during model validation provides clear error messages
3. CompatibilityFixStrategy: Remove repository disabling logic, replace with
informational logging for interpolated URLs
4. Add integration tests for repository URL interpolation:
- Test successful interpolation from environment variables and project
properties
- Test early failure when expressions cannot be resolved during model
building
The new approach enables legitimate use cases while providing early, clear
error
messages for unresolved expressions during the validate phase rather than
later
during repository resolution.
