Java Version

JDK 21

What's Changed

• Add cli option for specifying the submission encoding, thus disabling automatic encoding detection (try using --encoding).
• Try out the multi-language module: Considers all source code of supported languages (try using -l multi).
• Introduce additional similarity metrics (see Report Viewer changes).
• Improve the comparison algorithm performance for large workloads.
• In the visualization, improve highlighting of tokens that stretch across multiple lines.
• Add support for matches with different lengths on either side of a submission (a special case for a normalization mechanism).
• Fix bug in the subsequence match merging mechanism (try using --match-merging).
• Fix bug that causes crashes for min token match values above 25.

v6.0.0

Java Version

JDK 21

What's Changed

• The report viewer is now bundled into the JAR and will be launched automatically when running JPlag.
  • The CLI flag --mode allows running JPlag without launching the viewer or launching the viewer without running JPlag.
  • When the mode flag is not set, the mode is inferred based on the input. If a report ZIP is provided, the viewer is launched. If submissions are provided, JPlag is executed, and the viewer is launched for the results.
  • This means the hosted report viewer is now deprecated starting from this version of JPlag (will no longer be updated).
  • Note that the print functionality of the report viewer allows to export pages as PDF files.
• Improved subsequence match merging (--match-merging) to reduce its effect on unrelated program pairs.
• Fix a bug regarding preview features in Java code when running JPlag with Java > 21.
• Fix a bug where the normalization was not applied to the base code when running --normalize.
• Increase the default number of exported comparisons to 2500 (was previously 500).
• Added a CLI argument for the log level.
• Improved error messages for invalid submissions.
• Improved error handling for the Java and R language modules.

v5.0.0

Java Version

JDK 21

What's Changed

• New language modules (Javascript, Typescript, SCXML, LLVM-IR, EMF-model).
• Normalization mechanisms that improve resilience against obfuscation attacks.
  • Token sequence normalization to counteract statement insertion & reordering (supported for Java and C++, use --normalize).
  • Subsequence match merging to counteract a wide variety of obfuscation attack (supported for every language, use --match-merging).
• Support for Java 21 (including preview feature support).
• The former C/C++ module is now named c, the new cpp2 module now just named cpp
• Improved tokenization rules for the Java language module.
• Improvements to modeling plagiarism detection (Emfatic view, improved generic model view, normalization via --normalize).
• Increase the default number of exported comparisons to 500.
• More resilience regarding different file encodings.
• Cleaner log via progress bars.
