@zxxc make sure you're using sbt 0.13.17 or the latest 1.1.x; older versions don't work on Java 9 (I forget exactly when in the 1.x series support started). check |

I just ran into this issue while playing with Quick Edit: These are now MODULES and not just libraries that can be included. So slightly more complicated. |
|
/cc @jvican -- something to consider fixing on the bloop runner side of things? |
|
For reasons unknown (and perhaps I should find out) this doesn't reproduce with the coursier-based runners ([1]): |
|
@er1c Did the error go away with latest Bloop version? I remember you sent some patches to fix Bloop on Java 9+ but I'm not sure if they fixed this particular issue. |
|
Closing, since 2.10 and 2.11 development have ceased and the problem doesn't exist in later Scala versions. |
|
Hopefully there is still a ticket to make |
|
Hi, is this supposed to still be an issue? I tried this with: and |
Yes, we're aware the problem still exists in 2.10.7 and 2.11.12. As I wrote earlier:
We only keep a ticket open if the problem still exists in the HEAD of the current development branch (namely 2.13.x). |

@tacerus The getting started page https://docs.scala-lang.org/getting-started/index.html links to the JDK matrix https://docs.scala-lang.org/overviews/jdk-compatibility/overview.html The somewhat orthogonal issue of coping with classloaders and modules, either from CLI or other environments, is ongoing. |
|
Ah, apologies @SethTisue, I missed the version issue - I will attempt the latest release! Thanks! Thank you @som-snytt for linking the version matrix, that is very helpful! |
