SBT can't resolve dependencies through proxy - scala

Question

When I run sbt update i get this error
:: problems summary ::
:::: WARNINGS
::::::::::::::::::::::::::::::::::::::::::::::
:: UNRESOLVED DEPENDENCIES ::
::::::::::::::::::::::::::::::::::::::::::::::
:: org.scala-sbt#sbt;0.13.8: several problems occurred while resolving dependency: org.scala-sbt#sbt;0.13.8 {default=[default(compile)]}:

java.util.NoSuchElementException
Error during sbt execution: Error retrieving required libraries
(see /Users/$USER/.sbt/boot/update.log for complete log)
Error: Could not retrieve sbt 0.13.8
I've already set up the system to work with curl and homebrew using a proxy, but for some reason sbt won't work with the same settings. When I turn the proxy off, It just hangs for a few minutes before timing out and I don't get the aforementioned error.
I've also tried this, but without any luck
# export JAVA_FLAGS= -Dhttp.proxyHost=$domain -Dhttp.proxyPort=$portnum -Dhttp.proxyUser=$USER -Dhttp.proxyPassword=$password -Dhttps.proxyHost=$domain -Dhttps.proxyPort=$portnum -Dhttps.proxyUser=$USER -Dhttps.proxyPassword=$password -Dftp.proxyHost=$domain -Dftp.proxyPort=$portnum -Dftp.proxyUser=$USER -Dftp.proxyPassword=$password -Dhttp.nonProxyHosts=$noproxy -Dhttps.nonProxyHosts=$noproxy -Dftp.nonProxyHosts=$noproxy
# java ${JAVA_FLAGS}
The method I used to make hombrew and curl work is
export http_proxy=$http_proxy
export https_proxy=$http_proxy
export ftp_proxy=$http_proxy
export rsync_proxy=$http_proxy
export HTTP_PROXY=$http_proxy
export HTTPS_PROXY=$http_proxy
export FTP_PROXY=$http_proxy
export RSYNC_PROXY=$http_proxy
Any suggestions?
Thanks

I am not sure whether your JAVA_FLAGS included/exported to classpath or not, if not add it to classpath before trying this solution.
My Resoultion:
I don't know which IDE you are using, I faced same issue (I use IntelliJ 14). Try to relate to your IDE if you use different one, basically set it through VM arguments.
I have resolved this issue by adding vm arguments ...
Steps to add in IntelliJ:
File -> Default Settings -> under Build,Execution, Deployment
Build Tools -> SBT ->
JVM Options -> set in the "VM parameters" like this
-Dhttp.proxyHost=http://proxy.xxxx.com -Dhttp.proxyPort=8080 -Dhttps.proxyHost=http://proxy.xxx.com -Dhttps.proxyPort=8080 -XX:MaxPermSize=384M -Duser.home=/Users/yourusername/ -Dsbt.ivy.home=/Users/yourusername/.ivy2
Good Luck
