System Details

Windows 10, Java 8, JDK 22, Python 3.12

So I am new to development with scratch. I wanted to add block based programming functionality to Scratch 3.0 wherein we can Program in Python from basic blocks. I also want to have ESP32 connectivity with that. After some research, I cloned scratch-gui and scratch-vm but then while cloning and getting scratch-blocks ready, I am facing these errors. Also I am a beginner to this, so it would be nice if someone would be able to guide me through the process of modding scratch. Another thing is that Closure is officially shutting down soon so how to avoid errors regarding that. If someone can contribute, please do so.

Thanks.

Read the error message. You have to install Java (yes, not JavaScript here. Compiling scratch-blocks requires installing Java).

Thanks for the reply. But if you see the system specifications, I have already i stalled Java 8(Also added to PATH) and also installed JDK 22(Added to PATH as well). But the error still persists.
