The code is written mostly in Java (currently, source level 11). SWT library from Eclipse project is used for GUI that provides native components for each supported platform.

The project runs on Linux, Windows and macOS.

As there are millions of different networks, configurations and devices, please help with submitting a Pull Request if something doesn't work as you expect (especially macOS users). Any problem is easy to fix if you have an environment to reproduce it 😀

For that, download Intellij IDEA community edition and open the cloned project. Then, you can run Angry IP Scanner in Debug mode and put a breakpoint into the desired Fetcher class.

Use Gradle for building a package for your desired platform:

./gradlew or make in the project dir for the list of available targets.

./gradlew current would build the app for your current platform

The resulting binaries will be put into the build/libs directory. Run jar files with java -jar <jar-file>.

Deb and rpm packages can be built only on Linux (tested on Ubuntu). Windows installer can be built on Windows only.

./gradlew all will build packages for all OS (tested on Ubuntu only, see dependencies below).

On Ubuntu install the following packages:

sudo apt install openjdk-11-jdk rpm fakeroot

Install OpenJDK on other platforms as you usually do it.
