If SBT launcher is failing to download a new version of SBT from your proxy, and that ~/.sbt/boot/update.log is showing that you're getting 401 authentication errors, you can use the environment variable SBT_CREDENTIALS to specify where the ivy credential file is.

Either of these should work and download the new sbt version:

1. SBT_CREDENTIALS='/home/YOUR_USER_NAME/.ivy2/.credentials' sbt
2. Putting export SBT_CREDENTIALS="/home/YOUR_USER_NAME/.ivy2/.credentials" in your .bashrc (or .zshrc), start a new shell session and then run sbt

(You'll need have the ~/.ivy2/.credentials file setup like other answers here has shown)
