Build from Source

Building GraalVM binary

1. Install GraalVM

   • GraalVM is a substitution for JDK, you don't generally need another one, if you don't depend on specific functionality or performance of another JDK
   • Simplest way is to use brew cask as described here otherwise use static installation available for download here
   • Follow the installation closely, you will need to link bin folder to path and fix permissions on macOS

2. Install Native Image

   • You will use gu to install native-image, tutorial here

3. Checkout the project

   • Use your favorite tool to download this project
   • Unzip (if applicable) and cd to the directory

4. Build runnable Jar

   • ./gradlew shadowJar
   • This step builds the utility and prepares jar files for following step

5. Build Native Image

   • native-image --no-fallback -cp dragapult.app.MainKt -jar dragapult-app/build/libs/dragapult-app.jar dragapult
   • It optimizes code, injects runtime dependencies and wraps the utility with self executable binary. Please note that it will only build a binary that's applicable on your local machine. If you need to run it on some other system, use a host system to build it for you. Otherwise Matrix build on Github Actions works too.

6. Done!

   • You should see a dragapult binary ready to use in root directory of your project.
