sbt/sbt

A relaxed chat room about sbt (the interactive build tool). Also good for sbt help: Stack Overflow, or Lightbend subscription. https://www.scala-sbt.org/support.html has advice on where to go.

that one in particular confuses dimension and impedes understanding imho

i am mad about Global enough, that I've renamed it to Zero

so GlobalScope = (Zero, Zero, Zero, Zero)

@jvican interesting, ill give that a look - thanks!

@jvican

I'm having problems to resolve sbt-scripted

Is someone having the same problems too?

Igmar Palsenberg

@igmar

Is there any documentation on dependency resolving in modules

Jorge

@jvican

Documentation is code for now in 0.13.x series (this is going to change for 1.0.x, at least that's the plan)

If you want to see code to use ivy, see BaseIvySpecification

Another interesting source file is Defaults.scala

@eed3si9n I can kind of see the name Zero as the identity element of a monoid. But I wonder if the name will confuse people in a "build system" sense.

eugene yokota

@eed3si9n

I like zero because it reminds me of x, y, and z axes on 3D graph

we keep using the "axis" metaphor in the doc, zero makes it intruitive that its one of the values, nothing magical

much like This, you wouldn't come across Zero literally in build.sbt

one would just say foo in Global or Global / foo

Sukant Hajra

@shajra

Oh, I see. It's the origin.

@eed3si9n typo in http://developer.lightbend.com/blog/2017-06-15-sbt-1-0-beta2/: "anonymouse"

eugene yokota

@eed3si9n

yea

i caught it at some point in draft but the mouse returned in the final :)

there's also a typo about M5 and M6

ok. merged the typo fix. it'll be rolled out when Jenkins run

What's Josh working on these days? I just realized I haven't seen/heard from him in a while.

eugene yokota

@eed3si9n

he’s been keeping low profile since he left Lightbend. he’s been doing cool stuff, but I’d respect his privacy

Igmar Palsenberg

@igmar

@jvican Can I influence whats (if any) get's inherited from a parent module ?

Jorge

@jvican

@igmar I'm sorry but I don't get that question. What do you mean?

Igmar Palsenberg

@igmar

I have A -> B -> C, where C depends on B and A. Ik want to force version overrides in B, so that C enherits all dependencies from B and thus A

@jvican now I have to override them in both B and C

I want to say : inherit from B, unless overridden

Where A is Play, and B a common module, and C the application itself

Jorge

@jvican

I have no idea how to do that, I've never had that need

But I suggest you have a look at http://www.scala-sbt.org/0.13/docs/Dependency-Management-Flow.html and http://www.scala-sbt.org/0.13/docs/Library-Management.html

It should have everything you need to do that

Igmar Palsenberg

@igmar

I checked that, didn't tell me the right things

Sukant Hajra

@shajra

I normally only use the ".value" macro on the right-hand side of a setting... but is there a way to conditionally apply a setting based on a value. Like if I wanted to do something like if (someKey.value) addCompilerPlugin(somePlugin) else List.empty

I'm pretty sure that won't compile.

Sukant Hajra

@shajra

I suppose in this specific case, I can do something like libraryDependencies ++= { if (someKey.value) List(compilerPlugin(somePlugin) else List.empty }

Sukant Hajra

@shajra

Also, I just realized I don't know the best way to set a global setting in a .sbt file. Is that possible? It seems like all the settings in a .sbt file seem set at the project level.

Sukant Hajra

@shajra

hmm... using "inThisBuild" inside the project-level settings seems really counter-intuitive to me: http://www.scala-sbt.org/0.13/docs/Scopes.html#Build-level+settings

But I guess it works because it removes a "This" out of the key references, which essentially makes it no-longer a candidate for project-level scoping.

Dale Wijnand

@dwijnand

Yeah you replace the implicit, unresolved This axis value with the alternative, also unresolved, ThisBuild axis value. I tend not to nest it inside the root project's settings and just declare it at the root because it's unnecessary nesting.

Sukant Hajra

@shajra

okay, makes sense.

It's good to hear these things out loud from another person.

Gerard Vico

@HDBandit

hello guys

I have a question about the integration with an internal proxy for dependencies. I installed artifactory, and I am working with sbt. Sbt remains resolving a lot of time. I am monitoring the artifactory logs, and I don¡'t see accesses to the artifactory. What SBT is doing when is resolving?

Hi, I am trying to run some gatling simulations via sbt, but I am getting this error:

[error] Uncaught exception when running tests: java.lang.NoSuchMethodError: scala.Predef$.refArrayOps([Ljava/lang/Object;)Lscala/collection/mutable/ArrayOps;

        at sbt.ForkMain.main(ForkMain.java:121)

any pointers on how to resolve this error ?

@thsutton

Maybe you have a plugin and an SBT build that were built against different versions of Scala?
