Release Notes [–] Maven 3.9.6 – Maven (original) (raw)
The Apache Maven team would like to announce the release of Maven 3.9.6.
Maven 3.9.6 is available for download.
Maven is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project's build, reporting, and documentation from a central place.
The core release is independent of plugin releases. Further releases of plugins will be made separately. See the PluginList for more information.

Overview About the Changes
Regression fixes and other improvements from Maven 3.9.5. All users already on Maven 3.9.x are advised to upgrade.
This release updates Resolver to version 1.9.18. Maven itself received new features as ability to exclude plugins from validation, upgraded Eclipse Sisu version and updated plugins in core bindings.
The full list of changes can be found in our issue management system.
Potentially Breaking Core Changes (if migrating from 3.8.x)
- The Maven Resolver transport has changed from Wagon to “native HTTP”, see Resolver Transport guide.
- Maven 2.x was auto-injecting an ancient version of
plexus-utilsdependency into the plugin classpath, and Maven 3.x continued doing this to preserve backward compatibility. Starting with Maven 3.9, it does not happen anymore. This change may lead to plugin breakage. The fix for affected plugin maintainers is to explicitly declare a dependency onplexus-utils. The workaround for affected plugin users is to add this dependency to plugin dependencies until issue is fixed by the affected plugin maintainer. See MNG-6965. - Mojos are prevented to bootstrap new instance of
RepositorySystem(for example by using deprecatedServiceLocator), they should reuseRepositorySysteminstance provided by Maven instead. See MNG-7471. - Each line in
.mvn/maven.configis now interpreted as a single argument. That is, if the file contains multiple arguments, these must now be placed on separate lines, see MNG-7684. - System and user properties handling cleanup, see MNG-7556. As a consequence, this may introduce breakage in environments where the user properties were used to set system properties or other way around, for example see MNG-7887.
- Plugins and extensions used by your build are checked against Maven supported APIs and conventions: this “plugin validation” may report WARNINGs at the end of your build. See plugin validation documentation to better understand what to do when your build suffers from such warnings.
