🎉 The 3.0 release of Java to C# is here! 🎉

This is perhaps the largest release since this project was created over 10 years ago in October 2013. A lot of dust has been brushed off, a whole bunch of new platforms are now supported, several newer Java language features have been added, a new integration test runner helps protect against regressions, and dark mode is here!

The v3.0.0 release includes:

Cross-platform GUI support via Avalonia! This means you can now run the GUI utility on macOS and Linux, in addition to Windows. The GUI is a helpful tool for confirming the conversion and giving a convenient button to copy the output to your clipboard. It previously was written in WPF, so Avalonia was a natural fit. Additionally, this enabled...
Dark mode support! You can now toggle between light and dark mode in the UI.
The app now runs on .NET 6 LTS. This will be upgraded to .NET 8 LTS in the near future.
IKVM has been upgraded to 8.7, which enables support for new platforms like arm64
Because of the .NET 6, Avalonia, and IKVM 8.7 support above, we should now support the following platforms for both the GUI and CLI:
- Windows x64 and arm64
- macOS x64 and arm64
- Linux x64 and arm64
JavaParser has been upgraded to add support for multiple new Java language features. Additionally, the .jar is now handled by IKVM at build time instead of being included as a .dll.
Enabled by the JavaParser upgrade, the following Java features are now supported for translation (and are covered by integration tests):
- Java 7/9 try-with-resources (#53)
- Java 9 diamond inner classes don't translate fully, but at least do not error out (#57)
- Java 9 underscore as reserved keyword (#59)
- Java 10 type inference (#61)
- Java 11 lambda parameter type inference (#62)
Default and private interface methods are now converted to the C# 8 equivalents (#60)
GitHub Actions now automatically builds the app and runs unit tests for all PRs and commits to master
A new integration test runner converts test resource Java files to C#, compiles them, and asserts the output matches what is expected. These are automatically run as part of the GitHub Actions pipeline as well. Please try to add a test when adding a Java feature or fixing a bug!
Converting the unsigned right shift (>>>) binary operator is now supported.
The CLI now uses System.CommandLine for better argument handling, and most converter options are now available as command-line flags (#58)
The CLI now uses Microsoft.Extensions.Logging instead of Console.WriteLine.
An option has been added to turn off comment translation (#21)
Octal int/long literals are now translated correctly (#45)
Several common types are now converted automatically for convenience:
- Set: HashSet
- Map: Dictionary
- IAutoCloseable: IDisposable
- Iterator: IEnumerator
Various common exception types are now renamed to their .NET equivalents
System.out can now be converted to common Console equivalents (#18)
Interface extends are now translated
Fixes an issue where extra escaping backslashes were added to strings (#20)
Fixes an issue with array creation expressions (#38)
Miscellaneous smaller bug fixes and improvements
