Why do Mule Studio 3.4 Builds with Maven Fail or Hangs Indefinitely

Question

I'm running into the following problem attempting to build or a Mule app using Maven (using Mule 3.4). Similarly when I update dependencies, Eclipse will hang indefinitely when trying to download com.mulesoft.licm:licm:jar:1.1.3

Failed to read artifact descriptor for com.mulesoft.licm:licm:jar:1.1.3: 
Could not transfer artifact com.mulesoft.licm:licm:pom:1.1.3 from/to libs-releases
(http://dev.ee.mulesource.com/repository/content/repositories/libs-releases/): 
Connection to http://dev.ee.mulesource.com refused: Connection timed out: connect 
-> [Help 1] [ERROR] 

Here's my pom.xml:

Answer 1

A few of the MuleSoft POMs have references to their internal artifact repository which is not intended for public use. I believe it would be more responsible of them to use a profile for this or to use their own settings.xml to include this repository.

There are a number of ways to work around it. One solution is to mirror it to the public repository in your ~/.settings.xml:

    <mirrors>
    <mirror>
        <id>mule-ee-proxy</id>
        <name>Hack to not use dev.ee.mulesource.com</name>
        <url>https://repository.mulesoft.org/releases/</url>
        <mirrorOf>mule-ee-releases,mule-ee-snapshots,libs-releases,ext-releases</mirrorOf>
    </mirror>
</mirrors>

It's not pretty but it works.
