Despite this is a little old post, but here is how I compiled Liferay 7.0x from source code behind an authenticated proxy.
I downloaded source code:
git clone -b 7.0.x https://github.com/liferay/liferay-portal.git --depth 1 liferay-portal-7-ce
In file
build-common.xmlPut these properties after line of
<property environment="env" />
<property name="setproxy.proxy.host" value="proxyserver" />
<property name="setproxy.proxy.port" value="portnumber" />
<property name="setproxy.proxy.user" value="username" />
<property name="setproxy.proxy.pass" value="password" />
or
Put these properties in build.{user}.properties file
setproxy.proxy.host=proxyserver
setproxy.proxy.port=portnumber
setproxy.proxy.user=username
setproxy.proxy.pass=password
Configure Gradle and Maven as stated here
https://dev.liferay.com/pt/develop/tutorials/-/knowledge_base/7-0/setting-proxy-requirements-for-liferay-workspaceIn file
build-common.xml modify the setproxy ant task
from
<target if="setproxy.proxy.host" name="setproxy">
<setproxy proxyhost="${setproxy.proxy.host}" proxyport="${setproxy.proxy.port}" />
</target>
to
<target if="setproxy.proxy.host" name="setproxy">
<setproxy proxyhost="${setproxy.proxy.host}" proxyport="${setproxy.proxy.port}" proxyuser="${setproxy.proxy.user}" proxypassword="${setproxy.proxy.pass}" />
</target>
In file
build-dist.xmlFor every <target/> that contains <mirror-get/> add attribute "depends" as <target depends="setproxy">
Or change only for your choosed server, as in my case <target name="unzip-tomcat" depends="setproxy">
Maybe there is a simpler way but doing that worked for me and is ok for now :-)
