How to use sbt from behind proxy - in windows 7? - windows-7

Question

I am trying to run SBT on Windows 7. To do so I followed the steps in the similar thread "How to use sbt from behind proxy?".
I have the following relevant "System variables":
Variable name:
JAVA_OPTS
Variable value:
-Dhttp.proxySet=true -Dhttp.proxyHost=192.168.0.150 -Dhttp.proxyPort=8080
Variable name:
SBT_OPTS
Variable value:
-Dhttp.proxySet=true -Dhttp.proxyHost=192.168.0.150 -Dhttp.proxyPort=8080
and
Variable name:
SBT_HOME
Variable value:
C:\Program Files (x86)\sbt\
I also changed the content of C:\Program Files (x86)\sbt\conf\sbtconfig.txt
***** sbtconfig.txt BEGINNING *****
*Set the java args to high
-Xmx512M
-XX:MaxPermSize=256m
-XX:ReservedCodeCacheSize=128m
*Set the extra SBT options
-Dsbt.log.format=true
*Set proxy
-Dhttp.proxySet=true
-Dhttp.proxyHost=192.168.0.150
-Dhttp.proxyPort=8080
***** sbtconfig.txt END *****
Running cmd.exe I enter sbt. The cmd echos
Getting org.fusesource.jansi jansi 1.11 ....
After around 1 minute i get a lot of warnings and errors like:
[...]
:::: ERRORS Server access Error: Connection timed out: connect
url=https://repo.typesafe.com/typesafe/ivy-releases/org.fusesource.jansi/jansi/1.11.ivys/ivy.xml
[...]
which is exactly the same I get without the proxy settings. Also I was surprised when I entered the mentioned address in my browser and all I got was:
***** Browser display BEGINNING *****
{
"errors" : [ {
"status" : 404,
"message" : "File not found."
} ]
}
***** Browser display END *****
How can I find out if SBT is even trying to use the proxy, or there is a different problem?

Answer 1

Thank you Paweł for your answer.
This is what I found out:
"-Dhttp.proxySet=true" doesn't have any effect (for me at least)
The settings are prioritized in the following order:
SBT_OPTS overrides JAVA_OPTS overrides %SBT_HOME%conf\sbtconfig.txt
The Solution is either to set one of the environmental variables
JAVA_OPTS=-Dhttp.proxyHost=192.168.0.150 -Dhttp.proxyPort=8080 -Dhttps.proxyHost=192.168.0.150 -Dhttps.proxyPort=8080 -Dhttp.nonProxyHosts=localhost
OR
SBT_OPTS=-Dhttp.proxyHost=192.168.0.150 -Dhttp.proxyPort=8080 -Dhttps.proxyHost=192.168.0.150 -Dhttps.proxyPort=8080 -Dhttp.nonProxyHosts=localhost
OR to edit the %SBT_HOME%conf\sbtconfig.txt file :
***** sbtconfig.txt BEGINNING (hashtags in this file have been replaced by stars) *****
*Set the java args to high
-Xmx512M
*-XX:MaxPermSize=256m
-XX:ReservedCodeCacheSize=128m
*Set the extra SBT options
-Dsbt.log.format=true
*Proxy settings
-Dhttp.proxyHost=192.168.0.150
-Dhttp.proxyPort=8080
-Dhttps.proxyHost=192.168.0.150
-Dhttps.proxyPort=8080
***** sbtconfig.txt END *****

Answer 2

Let's take a look at your errors:
:::: ERRORS Server access Error: Connection timed out: connect url=https://repo.typesafe.com/typesafe/ivy-releases/org.fusesource.jansi/jansi/1.11.ivys/ivy.xml
Sbt is trying to use https, but you don't have proxy configuration for it.
Try setting https proxy variables:
https.proxyHost
https.proxyPort
I guess you could try the same values as for http proxy.

Answer 3

Go to your SBT folder and use the below command
set SBT_OPTS=-Dhttp.proxyHost=10.10.10.154 -Dhttp.proxyPort=8080 -Dhttps.proxyHost=10.10.10.154 -Dhttps.proxyPort=8080 -Dhttp.nonProxyHosts=localhost <Enter your IP settings >
and then
sbt.bat

Answer 4

sbt uses Gigahorse with OkHttp for parallel downloading. You can try turning it off by passing -Dsbt.gigahorse=false.
Another thing you could try is turning off https, and use http by passing -Dsbt.repository.secure=false
