ResolutionError$CantDownloadModule: Error downloading org.scala-sbt:sbt:1.6.0

[jjagielo]

I am currently running sbt 1.10.0 on my Ubuntu VM. When trying to run

./sim.py

I am met with the following error:

[info] [launcher] getting org.scala-sbt sbt 1.6.0  (this may take some time)...

Is this related to my installation of sbt? I've tried looking to other places and have not found anyone with a similar error. Also, when going to some of the links that caused the java.net.ConnectException, some seemed to not exist (Either pinging or searching them manually), such as here:

  "errors": [

      "status": 404,
      "message": "Item ivy-releases:org.scala-sbt/sbt/1.6.0/ivys does not exist"
    }
  ]
}

Hi,

It should be now fixed with : https://github.com/litex-hub/pythondata-cpu-vexriscv_smp/commit/1f8f8bb49538663759f043e83ebae311132fc3e5

[jjagielo]

It is still trying to get version 1.6.0 of sbt, unsure if that's just because of a print statement since I saw that the PR looked to update the build.properties to sbt 1.10.0. Also still leads to the 1.6.0 ivy.xml files that give the same .xml file as before.

[Dolu1990]

Hmm weird. Did you checked that your local copy of pythondata_cpu_vexriscv_smp/verilog/ext/VexRiscv/project/build.properties has sbt 1.10.0 set ?

For me it uses 1.10.0 when i run litex.

[jjagielo]

It's set to 1.10.0 so that's not the issue. I looked around at other build.properties configurations to see if they were still set to 1.6.0 and the only discrepency was here, but that was with sbt 1.9.7, not 1.6.0 so that wouldn't be the issue.

[Dolu1990]

linux-on-litex-vexriscv use pythondata-cpu-vexriscv-smp, not pythondata-cpu-vexriscv

The issue you have is kinda weird, i'm not aware of any other place where the sbt version is specified. Hmmm, maybe try to delete /home/jason/.ivy2 , aswell as deleting the whole pythondata-cpu-vexriscv-smp and recloning it (to be sure there is no dirty cache in it)

let's me know if it arrenge things, else, can you send me the full litex stdout in your terminal ?

[jjagielo]

Deleted /home/jason/.ivy2 as well as reverified my installation of sbt. It's all working now, thank you for your help!
