I'm trying to recreate a gitlab pipeline with dagger.
I have a build job that depends on the success of 2 other jobs [lint, unit-test].
How can I recreate this double dependency?

Hey! There's two ways. The natural way is if build has an actual dependency on an output from lint and unit-test. I doesn't sound like it has, so you can just use the language's natural concurrency features. Meaning that you can run lint and unit-test concurrently, and return on any error. If they succeed than code continues and build gets executed. Pseudo in Node.js:

await Promise.all([lint, unitTest])
await build

Here errors will throw an exception so it'll naturally exit, but you may want to catch or handle them somewhere.
