Gradle proxy configuration

Questions:

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.

Refinement over Daniel’s response:

HTTP Only Proxy configuration

gradlew -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=3128

HTTPS Only Proxy configuration

gradlew -Dhttps.proxyHost=127.0.0.1 -Dhttps.proxyPort=3129

Both HTTP and HTTPS Proxy configuration

gradlew -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=3128 -Dhttps.proxyHost=127.0.0.1 -Dhttps.proxyPort=3129

worked for me (with grade.properties in either homedir or projet dir, build was still failing). Thanks for pointing the issue at gradle that gave this workaround.

This is my gradle.properties, please note those HTTPS portion

systemProp.http.proxyHost=127.0.0.1
systemProp.http.proxyPort=8118
systemProp.https.proxyHost=127.0.0.1
systemProp.https.proxyPort=8118

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)

Try the following:

gradle -Dhttp.proxyHost=yourProxy -Dhttp.proxyPort=yourPort -Dhttp.proxyUser=usernameProxy -Dhttp.proxyPassword=yourPassoword

In my build.gradle I have the following task, which uses the usual linux proxy settings, HTTP_PROXY and HTTPS_PROXY, from the shell env:

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())
        }
    }
}

build.dependsOn setHttpProxyFromEnv

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

If you are behind proxy and using eclipse, go to Window Menu --> Preferences --> General --> Network Connections. Select the Active Providers as ‘Manual’.

Under Proxy entries section, click on HTTPS, click Edit and add proxy host & port. If username and password are required, give that as well. It worked for me!

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.

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://
