I am trying to get started with Chisel. Following the instructions on Chisel web page, I installed scala 2.11 and sbt, copied the build.sbt and Hello World example. However, I am unable to run the example. I am getting following errors.

tariq@ubuntu:~/work/scala-test$ sbt run

It appears sbt can't reach the internet (4th [info] line refers to this). sbt needs to be able to reach the internet in order to download packages.

Are you behind a proxy? Are you running this in a VM?

  • Yes, I am running in a VM. – Tariq Afzal Nov 24 '14 at 18:59
  • Then you will need to allow the VM to reach the internet in order to get these packages. If you are worried about security, you can do this only temporary, and once chisel completes its first run you can disable network access. – user2548418 Nov 24 '14 at 19:23
  • Actually, I am not blocking internet on the VM. I can ping github and berkeley.edu – Tariq Afzal Nov 26 '14 at 20:29
  • Can you ping repo1.maven.org (the host it is trying to connect to)? Are all ports open? It is using https. – user2548418 Dec 01 '14 at 23:06
