Description

Maven (3.5.3) is unable to download jars behind corporate proxy. 

settings.xml

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd">
 <proxies>
  <proxy>
 <id>skm--http-proxy</id>
 <active>true</active>
  <protocol>http</protocol>
 <host>my.proxy.ip.here</host>
  <port>8080</port>

 <password>*****</password>
 </proxy>
 </proxies>
 </settings>

Also tried this command:

set MAVEN_OPTS="-DhttpProxyHost=xxx.xx.xx.xx -DsocksProxyPort=8080"

After that, running 

mvn clean install -U

 results Not authorized by proxy , ReasonPhrase:Proxy Authorization Required. However, it does download other files (like javadocs etc) except jars, an actual library.
