New Features

Support for maven-based submissions. Assignments can now be configured to accept compact or maven submissions. In compact submissions, there is only an src folder with everything in there (main sources, tests, images, etc..). In maven submissions, the student must provide a pom.xml and organize the files into standard maven folders (src/main, src/test, ...). The student's pom.xml must match the teacher's pom.xml (associated with the assignment) to prevent students from adding arbitrary or problematic dependencies.

Enhancements

Internationalised code quality messages in the build report
Restructure Docker-related files into a dedicated deploy/ directory
Abort all pending submissions on application startup
Validate the Java version at application startup to ensure compatibility with SecurityManager requirements. Drop Project relies on SecurityManager for sandboxing submissions, which was deprecated in Java 18 and removed in Java 24.
Maven build of student submissions now uses the same Java version that is being used by Drop Project itself. This can be overridden by the property maven.useCurrentJdk=false.
