Expected behavior

I wanted to run a java program from a packaged electron app.

Actual behavior

The packaged electron app runs, but the java module does not work.

Steps to reproduce

Hello.
I'm trying to use Java with electron.

So, I installed it on my macOS like this:

nvm use 20.18.2

npm install --save java
npm install --save-dev electron@30.5.1

And, I rebuilt electron to connect the two:

npm install --save-dev @electron/rebuild

package.json
  "scripts": {
    "start": "electron .",
    "rebuild": "electron-rebuild -f -w java",
  }

npm run rebuild
node node_modules/java/postInstall.js

After that, when I test the program, it works fine:

npm run start

Finally, to package it, I followed guide to install and run electron-forge.

The packaging process completed successfully, and the program runs, but the program terminates at the point where the JAVA module is executed. I think it's because the packaged electron is not rebuilt to link to java.

What should I do? I need help.

Hi @neolord0, @electron/rebuild should already be run as part of the package and start commands in Electron Forge. There should be no need to run @electron/rebuild separately.

First of all, thank you for your kind answer.

After reading your answer, I found out that Electron Forge uses @electron/rebuild internally.

I want to use node-java module with Electron.
It says that node-java module should be rebuilt with @electron/rebuild with the following command.

package.json
"scripts": {
"start": "electron .",
"rebuild": "electron-rebuild -f -w java",
}

npm run rebuild
node node_modules/java/postInstall.js

Actually, it didn't run unless I did this.

When Electron Forge uses @electron/rebuild, is there a way to add options or postInstalling script like the above?
