Gradle proxy configuration

Question

I need web access from Gradle through a proxy server to use the Gradle Artifactory integration for Jenkins  To reduce possible causes for issues  I manually add the Artifactory plugin in build gradle and run it from command line   apply       apply from   http   gradle artifactoryonline com gradle plugins org jfrog buildinfo build-info-extractor-gradle 1 0 1 artifactoryplugin-1 0 1 gradle      Following this description I specified the following in  gradle gradle properties in my home directory   systemProp http proxyHost hostname systemProp http proxyPort 8080 systemProp http proxyUser de  username systemProp http proxyPassword xxx   With the above proxy configuration  that is otherwise known to work   it fails      11 33 17 699  ERROR   org gradle BuildExceptionReporter  Caused by  java io IOException  Server returned HTTP response code  407 for URL  http   gradle artifactoryonline com gradle plugins org jfrog buildinfo build-info-extractor-gradle 1 0 1 artifactoryplugin-1 0 1 gradle   I have two proxy servers to choose from  and one always responds with 407  Proxy authentication required   the other with 502  Bad gateway   so obviously  the proxyHost and proxyPort options are used   As the user name  based on an Active Directory user  contains a backslash  I tried both    and    but neither worked  The user specified is different from the user that is logged in to the machine and Active Directory  This user s credentials aren t valid for the proxy  so I need to be able to specify a different user   Setting the same options in Jenkins  or Artifactory s GUI worked

There are 2 ways for using Gradle behind a proxy :

Add arguments in command line

(From Guillaume Berche's post)

Add these arguments in your gradle command :

-Dhttp.proxyHost=your_proxy_http_host -Dhttp.proxyPort=your_proxy_http_port

or these arguments if you are using https :

-Dhttps.proxyHost=your_proxy_https_host -Dhttps.proxyPort=your_proxy_https_port

Add lines in gradle configuration file

in gradle.properties add the following lines :

systemProp.http.proxyHost=your_proxy_http_host
systemProp.http.proxyPort=your_proxy_http_port
systemProp.https.proxyHost=your_proxy_https_host
systemProp.https.proxyPort=your_proxy_https_port

(for gradle.properties file location, please refer to official documentation https://docs.gradle.org/current/userguide/build_environment.html

EDIT : as said by @Joost : A small but important detail that I initially overlooked: notice that the actual host name does NOT contain http:// protocol part of the URL...

In case my I try to set up proxy from android studio Appearance  amp  Behaviour    System Settings    HTTP Proxy  But the proxy did not worked out so I click no proxy      Checking NO PROXY will not remove the proxy setting from the   gradle properties Global   You need to manually remove it    So I remove all the properties starting with systemProp for example - systemProp http nonProxyHosts   local  localhost

If this issue with HTTP error 407 happened to selected packages only then the problem is not in the proxy setting and internet connection  You even may expose your PC to the internet through NAT and still will face this problem  Typically at the same time you can download desired packages in browser  The only solution I find  delete the  gradle folder in your profile  not in the project   After that sync the project  it will take a long time but restore everything

If you are behind proxy and using eclipse  go to Window Menu -- gt  Preferences -- gt  General -- gt  Network Connections  Select the Active Providers as  Manual    Under Proxy entries section  click on HTTPS  click Edit and add proxy host  amp  port  If username and password are required  give that as well  It worked for me

An update to  sourcesimian  s and  kunal-b s answer which dynamically sets the username and password if configured in the system properties   The following sets the username and password if provided or just adds the host and port if no username and password is set    task setHttpProxyFromEnv       def map     HTTP PROXY    http    HTTPS PROXY    https       for  e in System getenv              def key   e key toUpperCase           if  key in map                def base   map key                Get proxyHost port  username  and password from http system properties                 in the format http   username password proxyhost proxyport             def  val1 val2    e value tokenize                    def  val3 val4    val1 tokenize                     def userName  password    val4 tokenize                  def url   e value toURL                 println   - systemProp   base  proxy   url host    url port               System setProperty    base  proxyHost   url host toString                System setProperty    base  proxyPort   url port toString                System setProperty    base  proxyUser   userName toString                System setProperty    base  proxyPassword   password toString

Create a file called gradle properties inside the project folder where the build gradle file is present  Add the following entry        systemProp http proxyHost proxy url      systemProp http proxyPort proxy port      systemProp http proxyUser USER      systemProp http proxyPassword PWD      systemProp https proxyHost proxy url       systemProp https proxyPort proxy port      systemProp https proxyUser USER      systemProp https proxyPassword PWD   If you are using DNS for proxy then add it like systemProp https proxyHost www proxysite com  For IP just specify the IP with out http    or https     Check gradle official doc for more details and setting up proxy at global level

For me  works adding this configuration in the gradle properties file of the project  where the build gradle file is   systemProp http proxyHost proxyURL systemProp http proxyPort proxyPort systemProp http proxyUser USER systemProp http proxyPassword PASSWORD systemProp https proxyHost proxyUrl  systemProp https proxyPort proxyPort systemProp https proxyUser USER systemProp https proxyPassword PASSWORD   Where    proxyUrl is the url of the proxy server  http           proxyPort is the port  usually 8080   USER is my domain user  PASSWORD  my password  In this case  the proxy for http and https is the same

Based on SourceSimian s response  this worked on Windows domain user accounts  Note that the Username does not have domain included   task setHttpProxyFromEnv       def map     HTTP PROXY    http    HTTPS PROXY    https       for  e in System getenv              def key   e key toUpperCase           if  key in map                def base   map key              def url   e value toURL               println   - systemProp   base  proxy   url host    url port               System setProperty    base  proxyHost   url host toString                System setProperty    base  proxyPort   url port toString                System setProperty    base  proxyUser    Username               System setProperty    base  proxyPassword    Password                     build dependsOn setHttpProxyFromEnv

Using a very simple  Request a URL  Java program  I was able to replicate the issue   http proxyUser and http proxyPassword seem to be non-standard  albeit popular  options  as they re not described in the Java reference page linked from the Gradle tutorial  even though the Gradle manual mentions them   It seems Java programs that wish to support proxy authentication need to do this manually  and I was able to do this using the code on the linked page      I submitted this issue  and a fix  to the Gradle issue tracker  Raised issue GRADLE-1556 was resolved in 1 0-milestone-8  Feb 2012
