An excellent AngularJS Roundup article

I did not write this article. I am noting it here for personal reference and sharing with others. I recommend this for reference, not necessarily a straight read.

Please know, you will not become good at any script or language via osmosis.  Open an IDE or text editor and work through examples. Get familiar.  It is hard work, but rewarding when it pays off.

IntelliJ importing Maven Project: No Route to Localhost

I will NOT be the only person to encounter this problem.
So here is my quick blog.

Using Intellij on Mac OSX Yosemite 10.10.1:

  • When trying to create a new project from existing maven sources
    the IDE would not switch to the “Select a profile” view.
  • The IDE did not give me a message.  It just wouldn’t advance. This forced me to review the logs

The logs live in :  MacintoshHD ▸ Users ▸ {user-name} ▸ Library ▸ Logs ▸ IntelliJIdea14

I could look at the logs directly through the Finder (open in a text editor) or use the convenient Console application in the application Launchpad.

I was getting this problem:  java.rmi.ConnectIOException: Exception creating connection to: localhost; nested exception is:

It was buried among an unending stack:

This problem is driven my maven itself.

Context:  I work for a very large Enterprise with a burdensome amount of rules to access anything either in or out of the network.

Sifting through the code I eventually found the “no route to localhost” error line.

From past experience Maven proxy settings are unable to route to certain internal IPs through the proxy.

I have a “settings.xml” file sitting under my /Users/{user-name}/.m2 directory to enforce usage of certain repos and setting proxy values.  So I had to ensure my <nonProxyHosts> were set correctly:

    <proxies>
        <proxy>
            <active>true</active>
            <protocol>http</protocol>
            <host>144.44.144.14</host>
            <port>80</port>
            <username>{usZer-name}</username>
            <password>{passW0rd}</password>
            <nonProxyHosts>*.local|169.254/16|localhost</nonProxyHosts>
        </proxy>
    </proxies>

My initial mistake was using a “,” comma for a separator.  This is not correct for Maven.  It needs a Pipe {“|”}.

I corrected this and my project import problems have been resolved.

Happy coding.
