Project is broken out of the box... about scala-seed.g8 HOT 5 CLOSED

looks like a manifestation of scala/scala-dev#480, which is a regression in Scala 2.12.5 on Java 9 & 10

in the short term, if you are trying to get started with the language, you should find that using Java 8 works fine as a workaround.

but also, I don't understand why this is happening to you, because https://github.com/scala/scala-seed.g8/blob/2.12.x/src/main/g8/build.sbt says 2.12.4, not 2.12.5. because we intentionally haven't merged #22 yet, exactly because of scala/scala-dev#480

if I try to reproduce the problem on my own machine, I can't. it works fine, as seen in this transcript: https://gist.github.com/SethTisue/f727ae33a31e01533a1fd4f6468968f3

anyone have an idea how or why @aturner-tvpage's experience was different?

from scala-seed.g8.

This is weird. I created a clean directory, and re-ran, and it worked as advertised. I had created another project moments before the first time, updating the Scala version to the current release, then relatively quickly, re-ran the sbt new, and it failed. Is it possible something somewhere was caching?

That does in fact appear to be what is occurring!

I build my project that asks for Scala 2.12.5 and it tried to build (and fails right now because, I was half way through something).
Create a new project, run sbt test and it fails! How interesting..

Is it possible something somewhere was caching?

maybe it just overwrote the directory from last time and you ended up with a mix of stuff?

I'm not sure what your other comment is about, maybe ask on https://users.scala-lang.org
