GNUBridge is a Contract Bridge program written in Java and available under GNU public license v. 3.
Note, there haven't been any updates to this project for awhile.
There's no distribution provided, so you can either build yourself a jar with %./gradlew build and run as executable jar or run directly with ./gradlew run.
Need a minimum of Java 1.5. Builds with Gradle wrapper (ie: %./gradlew build). Need at least 1Gb to run (more is better), so in IDE you need to pass a VM option -Xms1024M. This is already configured for gradle wrapper.
