Gradle proxy configuration

Refinement over Daniel's response:

HTTP Only Proxy configuration

gradlew -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=3128 "-Dhttp.nonProxyHosts=*.nonproxyrepos.com|localhost"

HTTPS Only Proxy configuration

gradlew -Dhttps.proxyHost=127.0.0.1 -Dhttps.proxyPort=3129 "-Dhttp.nonProxyHosts=*.nonproxyrepos.com|localhost"

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 "-Dhttp.nonProxyHosts=*.nonproxyrepos.com|localhost"

Proxy configuration with user and password

gradlew -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=3128 - Dhttps.proxyHost=127.0.0.1 -Dhttps.proxyPort=3129 -Dhttps.proxyUser=user -Dhttps.proxyPassword=pass -Dhttp.proxyUser=user -Dhttp.proxyPassword=pass -Dhttp.nonProxyHosts=host1.com|host2.com

worked for me (with gradle.properties in either homedir or project dir, build was still failing). Thanks for pointing the issue at gradle that gave this workaround. See reference doc at https://docs.gradle.org/current/userguide/build_environment.html#sec:accessing_the_web_via_a_proxy

Update You can also put these properties into gradle-wrapper.properties (see: https://stackoverflow.com/a/50492027/474034).

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

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

Check out at c:\Users\your username\.gradle\gradle.properties:

systemProp.http.proxyHost=<proxy host>
systemProp.http.proxyPort=<proxy port>
systemProp.http.proxyUser=<proxy user>
systemProp.http.proxyPassword=<proxy password>
systemProp.http.nonProxyHosts=<csv of exceptions>
systemProp.https.proxyHost=<proxy host>
systemProp.https.proxyPort=<proxy port>
systemProp.https.proxyUser=<proxy user>
systemProp.https.proxyPassword=<proxy password>
systemProp.https.nonProxyHosts=<csv of exceptions seperated by | >

Try the following:

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

---

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)

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

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...

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

In case my I try to set up proxy from android studio Appearance & 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

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())
        }
    }
}

Edit your ~/.gradle/gradle.properties file, then add the following:

org.gradle.jvmargs=-DsocksProxyHost\=127.0.0.1 -DsocksProxyPort\=1080 -DhttpProxyHost\=127.0.0.1 -DhttpProxyPort\=1081 -DhttpsProxyHost\=127.0.0.1 -DhttpsProxyPort\=1081

DsocksProxyHost is the socks5 proxy host

DhttpProxyHost is the http proxy host

DhttpsProxyHost is the https proxy host

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.

---

If you are using flutter, add the following line in android/gradle.properties

systemProp.http.nonProxyHosts=*.local, localhost

---

In the kotlin .kts setting files the properties should be defined like this:

extra["systemProp.http.proxyHost"]="127.0.0.1"
extra["systemProp.http.proxyPort"]="12345"

---

I met the same issue after I installed an older version of SDK and set JAVA_HOME in .zshrc, none of the solutions above help me but finally RESTARTED COMPUTER(Mac) then the error gone.

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!
