Proxy settings for java8 template

[padiazg]

Gradle needs proxy options to be specified explicitly, ignores http_proxy, https_proxy and no_proxy environment variables.

Expected Behaviour

Grable run the build successfully

Step 9/24 : RUN gradle build

BUILD FAILED in 47s

The command '/bin/sh -c gradle build' returned a non-zero code: 1
2018/12/20 11:13:54 ERROR - Could not execute command: [docker build --build-arg http_proxy=http://10.118.1.80:3128/ --build-arg https_proxy=http://10.118.1.80:3128/ -t padiazg/crc-bcp:latest .]

Possible Solution

Two successful options:
a) Update GRADLE_OPTS in the Dockerfile like this

ENV GRADLE_OPTS="-Dorg.gradle.daemon=false -Dhttp.proxyHost=10.118.1.80 -Dhttp.proxyPort=3128 -Dhttps.proxyHost=10.118.1.80 -Dhttps.proxyPort=3128"

b) Create gradle.properties at the root if the java8 template with following content:

systemProp.http.proxyHost=10.118.1.80
systemProp.http.proxyPort=3128
systemProp.http.nonProxyHosts=localhost|127.0.0.1|10.22.*|10.118.*
systemProp.https.proxyHost=10.118.1.80
systemProp.https.proxyPort=3128
systemProp.https.nonProxyHosts=localhost|127.0.0.1|10.22.*|10.118.*

Steps to Reproduce (for bugs)

You must be behind a proxy, without direct access to the Internet.

$ faas-cli new test-function --lang java8
$ faas-cli build

Context

Both solutions proposed above works, but you have to modify the template after it is downloaded.
You need to do this for every project you are creating, of if for some reason you download the template again.
Also the template folder is specified in .gitignore, so this configuration wont be saved to your git repository.
