Override of Prettier plugins during code transformation seems not possible with 8.2.1 release

[vishal423]

Overview of the issue

I am trying to upgrade JHipster Svelte blueprint to support 8.2.1 release, however, I don't see an easy way to override the prettier plugins to include prettier-plugin-svelte to transform the svelte code.

If you override to include prettier plugins, code generation fails with below stack trace:

 - applying multi-step templates
✔ Git repository initialized.
   create .prettierrc
   create .prettierignore
✔ prettier configuration files committed to disk
- updating package.json dependencies versions
- prettifying sonar-project.properties
- adding package-info.java files

Related issues

It seems the issue occurs due to switch to use web workers for prettier and eslint transform tasks. Serialization seems to not work correctly when overriding the plugins.

In my tests (using built-in plugins) if you pass the module url it should work:

bootstrapGenerator.prettierOptions.plugins.push(import.meta.resolve('prettier-plugin-svelte', import.meta.url));

Thanks @mshima, the suggested syntax seems to work fine. I will close the ticket
