Gradle proxy installation

Question

I am having problems creating Android projects on a server on the corporate network behind a Jenkins proxy server. Tried with both jenkins gradle and gradlew. Following is the error message after turning on debug mode.

This is the content of gradle.properties.

systemProp.http.proxyHost=proxy.server
systemProp.https.proxyHost=proxy.server
systemProp.http.proxyPort=8080
systemProp.https.proxyPort=8080

I tried passing the proxy settings from jvm flags and tried using gradle versions 3.3 to 3.5. Is there something I'm missing?

Answer 1

For me, issue was a prefix http! If this is your case, remove the prefix http/https!

gradle.properties , :

systemProp.http.proxyHost=http://squid.proxy.com
systemProp.http.proxyPort=8080
systemProp.https.proxyHost=http://squid.proxy.com
systemProp.https.proxyPort=8080

---

gradle:

systemProp.http.proxyHost=squid.proxy.com
systemProp.http.proxyPort=8080
systemProp.https.proxyHost=squid.proxy.com
systemProp.https.proxyPort=8080

gradle.configuration , , .

: (https://docs.gradle.org/current/userguide/build_environment.html#sec:accessing_the_web_via_a_proxy)

"http.//„https:“ systemProp.http.proxyHost „www.host.com“. systemProp.http.proxyUser proxypassword, .

systemProp.proxySet=true
systemProp.http.keepAlive=true
systemProp.http.proxyHost=www.host.com
systemProp.http.proxyPort=port
systemProp.http.proxyUser=username_ifneeded
systemProp.http.proxyPassword=password_needed
systemProp.http.nonProxyHosts=local.net|some.host.com

systemProp.https.keepAlive=true
systemProp.https.proxyHost=host
systemProp.https.proxyPort=port
