trouble running the server on my laptop

[michielbdejong]

Hi!

I installed Akka, then copied sbt and dist-sbt into this repo, then ran ./sbt and it all seems to work except:

exception caught when loading module class TurtleWriter$: java.lang.AssertionError: assertion failed: duplicate module class TurtleWriter$#363075; previous was class TurtleWriter$#363069

Any idea what might be causing this?

The sbt I downloaded was from akka-quickstart-scala btw

[bblfish]

yes, I updated the banana-rdf LDP namespaces, which were pre final spec.
I need to push those minor changes and make a release of banana-rdf too. I'll ping back here as soon as I have done that.

[bblfish]

I published a SNAPSHOT version of banana-rdf with the updates to this and sibling directories.
https://oss.sonatype.org/content/repositories/snapshots/net/bblfish/rdf/banana-rdf_2.13/0.8.5-SNAPSHOT/

I am not 100% sure if my build is setup for picking up those snapshots though. But it should now just work by running sbt from the command line and then trying to compile the project . If that works then run test should start the server with the root being the test directory.

The Akka version of sbt should be ok too. I think I use the one from brew

[bblfish]

Should not be closed quite yet.
This is helping me bump up the priority for adding an automated build process #12

[bblfish]

Travis has now been setup and the build is passing, so the dependencies all seem to be working now.

[michielbdejong]

I switched to brew install sbt now, but seeing:

Maybe I should use Java 16 instead of Java 15?

EDIT: Ah never mind, I had accidentally deleted ./project/Dependencies.scala from the rpo

[michielbdejong]

got a different error now:

Hm, or maybe that's still exactly the same error, actually

[michielbdejong]

Tried checking out https://github.com/co-operating-systems/Reactive-SoLiD from scratch, but same result :(

[michielbdejong]

Could something be cached somewhere?
Trying with https://stackoverflow.com/questions/33435284/how-to-force-sbt-to-redownload-dependencies-when-ivy-cache-corrupted now.

[michielbdejong]

Hm, still seeing the same problem after clearing the ivy cache...
