title: Intellij Idea debug could not access maven repo:connection refused
body: <p>I am starting Intellij Idea using gradle,throw this error:</p>
  
  <pre><code>&gt; Could not resolve com.sportswin.soa:ws-red-envelope-api:0.0.1-SNAPSHOT.
           &gt; Unable to load Maven meta-data from https://nexus.example.com/repository/maven-release/com/sportswin/soa/ws-red-envelope-api/0.0.1-SNAPSHOT/maven-metadata.xml.
              &gt; Could not get resource 'https://nexus.example.com/repository/maven-release/com/sportswin/soa/ws-red-envelope-api/0.0.1-SNAPSHOT/maven-metadata.xml'.
                 &gt; Could not GET 'https://nexus.example.com/repository/maven-release/com/sportswin/soa/ws-red-envelope-api/0.0.1-SNAPSHOT/maven-metadata.xml'.
                    &gt; Connect to 127.0.0.1:7890 [/127.0.0.1] failed: Connection refused (Connection refused)
  </code></pre>
  
  <p>I am already unset proxy in terminal:</p>
  
  <pre><code># proxy list
  alias proxy="export all_proxy=socks5://127.0.0.1:7891"
  alias unproxy="unset all_proxy"
  </code></pre>
  
  <p>unset proxy:</p>
  
  <pre><code>unproxy
  </code></pre>
  
  <p>and the Intellij Idea using no proxy setting, why the proxy still using <code>127.0.0.1:7891</code> when debugging?</p>
