Unresolved dependencies com.typesafe.play sbt-plugin 2.2.2 inside proxy

The compilation works outside the proxy. I am getting the following unresolved dependencies within the corp network, can you please help (I have the right proxy settings since a lot of other packages do get pulled)

Hey @anupamaggarwal,

Have you seen this page at sbt docs:

https://www.scala-sbt.org/1.x/docs/Setup-Notes.html#HTTP%2FHTTPS%2FFTP+Proxy

Hope this helps.

Best.

Thanks for your suggestion, yeah I have the proxy properties set, it’s able to download other dependencies but not sbt plugin for play.

Our corporate proxy requires authentication, seems like sbt has issues resolving behind ntlm authentication

Getting lots of exceptions thrown from

at com.sun.security.ntlm.Client.type3(Client.java:161)
[debug] 	at sun.net.www.protocol.http.ntlm.NTLMAuthentication.buildType3Msg(NTLMAuthentication.java:250)

Even though all proxy settings are set. (including http.proxyPassword and http.proxyUserName (and their https counterparts)

I was able to resolve this by setting proxy (for some reason it was not picking up the arguments being passed from -DhttpX but explicitly setting http_proxy and https_proxy worked)
