Vscode-java: Failure to install Gradle distribution behind proxy

[Geeprox]

Environment
Operating System: Windows 7
JDK version: 1.8.0_144
Visual Studio Code version: 1.19.1
Java extension version: 0.16.0

The same problem still exists, not resolved

https://github.com/redhat-developer/vscode-java/issues/383

I installed Gradle like this:

C:/gradle43
- bin/
- lib/
...

and set environment variable:

GRADLE_HOME --- C:\gradle43
PATH ---- %GRADLE_HOME%\bin

and I can run 'gradle -v' in the cmd

and I set this in VSCode settings:

"java.jdt.ls.vmargs": "-noverify -Xmx1G -XX:+UseG1GC -XX:+UseStringDeduplication -DGRADLE_HOME=C:/gradle43"

But

the process still hangs at about 84%!

VSCode and even the operating system will be very slow!

( But if I set this is VSCode settings:

"java.jdt.ls.vmargs": "-Dhttp.proxyHost=myHost -Dhttp.proxyPort=myPort -Dhttp.proxyUser=myUsername -Dhttp.proxyPassword=myPassword -Dhttps.proxyHost=myHost -Dhttps.proxyPort=myPort -Dhttps.proxyUser=myUsername -Dhttps.proxyPassword=myPassword"

The process will hangs at about 85%!

I think it's not caused by my proxy, because I alse set 'http.proxy' and my VSCode can access the internet, though I have to set 'http.proxyStrictSSL' to 'false', maybe the root cause is here?)

So

If you can't fix this problem, can you set a timeout? If the process hangs more than 30s(or N seconds), then stop it. Thanks!

[snjeza]

@Geeprox could you build your project using the gradle command line?

[Geeprox]

@snjeza No, I can't. It also says that could not download blabla because connect time out .

But we use a tool called armadillo.py to release the apk in my company.

So if it cannot be resolved, can you also set a timeout and break the process? Or maybe package the necessary dependence in the extension instead of downloading from the internet? Thanks~

@Geeprox we can't do that because we don't know what dependencies are required by your project. You can try to create Eclipse's .project/.classpath files and skip the gradle importer using the following property:

"java.import.gradle.enabled": false

or try to avoid https with the following setting:

jcenter{url "http://jcenter.bintray.com/"}

instead of

jcenter()

[Geeprox]

"java.import.gradle.enabled": false helps me, Tkx!

[texasbruce]

Why is this closed? Auto downloading Gradle is still broken when it's behind proxy. It should respect "http.proxy" variable and use it.

[snjeza]

It is an upstream issue related to https://jcenter.bintray.com.
