Using own Java libraries with jsweet

[Krzysztof-Dziardziel]

Hey,

Whenever I try to use JSweet with a code that uses another Java library, I'm getting errors:

[ERROR] Failed to execute goal org.jsweet:jsweet-maven-plugin:3.1.0:jsweet (generate-js) on project malana: transpilation failed: transpilation failed with 346 error(s) and 0 warning(s)

Could anyone point me on how should I change the libraries so I can use them? Seems like I need to create a candy (?), but I have no idea on where to start as I don't have much experience in Java (JS background here!).

I would very appreciate any suggestions :)

Hello @Krzysztof-Dziardziel,

Did you read those pieces of documentation:
Generating JSweet candies from existing TypeScript definitions

And
Packaging a JSweet jar (candy)

?

You have a quick start in it :) I hope it still works though 🤞

That would be good that you read a bit about Maven because you are going to need it 😄
In addition, basic usage skills are enough to use JSweet https://maven.apache.org/guides/getting-started/maven-in-five-minutes.html

Hey @Krzysztof-Dziardziel, as @lgrignon mentioned, if you want to use a 3rd-party lib in your jsweet project, you have to make a candy for this lib.
