Hi KliminV! 👋

Welcome, and thank you for opening your first PR in the repo!

Please wait for triaging by our maintainers.

Please take a look at our contributing guide.

[KliminV]

I think no unit tests are needed. However I would be happy to update documentation if needed
Also, can't link issue myself #90

[KliminV]

@Haarolean could you please take a look?

[Haarolean]

why would we need this all profile?

[KliminV]

That's default - to build all modules if no profile provided.

Let's confirm scope:

• we need to get rid of skipUiBuild and replace it with profile
• add frontend as part of local build

Is that all?

Then I suggest declare frontend as separate module - that allows us to avoid using properties to skip build stages

[Haarolean]

We don't quite need the contract profile. To achieve the same one can build just one module, contract.
What we need is a jar without the frontend, basically what skipUiBuild does now, but as a profile.

[Haarolean]

We'd need to get rid of this property altogether replacing it with a separate profile for transparency
