scala - SBT is unable to find credentials when attempting to download from an Artifactory virtual repo

Question

I'm trying to run SBT behind a corporate firewall. Another team has configured an Artifactory proxy. This proxy works fine with anonymous access switched on, but when we make it require a password thinks start to go wrong.

When I run SBT on my workstation I get the following error:

[error] Unable to find credentials for [Artifactory Realm @ coderepo.xxx.amrs.bigco.com]

The result of this is that I cannot bootstrap sbt:

[warn]  ::::::::::::::::::::::::::::::::::::::::::::::
[warn]  ::          UNRESOLVED DEPENDENCIES         ::
[warn]  ::::::::::::::::::::::::::::::::::::::::::::::
[warn]  :: org.scala-lang#scala-library;2.10.6: not found
[warn]  :: org.scala-sbt#sbt;0.13.12: not found
[warn]  :: org.scala-lang#scala-compiler;2.10.6: not found
[warn]  ::::::::::::::::::::::::::::::::::::::::::::::

I've tried putting a .credentials file in ~/.sbt and also ~/.ivy2: I have been testing variations on the following, all of which do not work:

realm=Artifactory Realm @ coderepo.xxx.amrs.bigco.com
host=coderepo.xxx.amrs.bigco.com
user=<username>
password=<pwd>

I'm guessing that this error means that it was unable to locate a credentials definition that matched the realm, so I tried a number of versions of the first line in both locations:

realm=Artifactory Realm
realm=[Artifactory Realm @ coderepo.xxx.amrs.bigco.com]
realm=coderepo.xxx.amrs.bigco.com

None of which seem to have any impact at all.

So what is the correct way to allow SBT to authenticate with username & password to a password protected Artifactory repository?

UPDATE0: According to the Ivy documentation, the most likely realm name is simply "Artifactory Realm". According to the SBT documentation, the correct default location of the credentials file should be %USERPROFILE%/.sbt/.credentials (yes, I'm using Windows). Even after deleting the .credentials file in my .ivy2 directory it still doesn't work.

UPDATE1: Relevant but not actually helpful:

• SBT not passing credentials when publishing to Artifactory
• Sbt can't authorize in Artifactory

UPDATE2: I'm starting to suspect that this is a bug in sbt - I've added an issue here: https://github.com/sbt/sbt/issues/2817

Answer 1

See this question for details on how to configure global credentials.

To summarise:

If you need to boot SBT from a proxy repository, set the system property sbt.boot.credentials to point to your credentials file. You can do this in your %CSIDL_PROGRAM_FILESX86%/sbt/conf/sbtconfig.txt, for example:

-Dsbt.boot.credentials=/Users/my-user-name/.sbt/credentials

Alternatively you can use the SBT_CREDENTIALS environment variable for the same purpose.

For Artifactory, the realm in the credentials file should be set to:

realm=Artifactory Realm

For authenticating dependency artifact retrieval, create a file like %USERPROFILE%/.sbt/0.13/plugins/my-credentials.sbt with a credentials setting. For example:

credentials += Credentials(Path.userHome / ".sbt" / "credentials")
