Build FTB App for Windows

A guide for building the original Electron-based (and Overwolf free) FTB App.

Preface

Prerequisties

• Java 11
• Launch4J

Pitfalls

• No automatic updating, you will need to build the app again to receive updates.

Guide

1. Clone the modpacklauncher repository recursively, ensuring that submodules are initialised.
   • Build the project with ./gradlew.bat build.
2. Create a directory to store your build of the FTB App.
   • Create a subdirectory bin
   • Copy the contents of web/release/win-unpacked to your bin directory
3. Download an archive of the latest Java 11 JRE
   • Extract the archive to the directory for your FTB App
   • You should have a directory named similar to jdk-11.0.9.1+1-jre
4. Use Launch4J to create a wrapped executable of modpacklauncher.
   • Under 'Basic'
     • Set the 'Output file' to ftbapp.exe in your directory
     • Set the 'Jar' to the file in build/libs ending -all.jar
     • Set the 'Icon' to ftbl.ico
   • Under 'JRE'
     • Set the 'Bundle JRE path' to the name of your JRE directory (e.g. jdk-11.0.9.1+1-jre)
     • Tick '64-Bit'
     • Set the 'Min JRE version' to 11
   • Use 'Build wrapper' to create the wrapped executable
   • (you may wish to save this configuration to make future updates quicker)

You now have your own, Overwolf-free, copy of the FTB App for Windows - just run your ftbapp.exe executable.
