I have been using Maven for ages now. I was running on 3.0.3 till last week. Being a Maven evangelist it is unlike of me to have not moved onto the latest version for so long. But I did linger on with 3.0.3 longer than I was comfortable. And the reason was whenever I tried to move to 3.0.4 it will simply not download the dependencies, while working behind proxy. I would get a long list of warnings and errors starting with the following.
Failed to retrieve plugin descriptor …
This was irritating to say the least. This weekend I rolled up my sleeves and set out to find what I was doing wrong. Turned out my beloved Maven was doing it wrong this time – and not me for a change, which is good. Apparently they did not add a jar that is required for working behind proxy [JIRA].
So, what do we do to fix it? Like most of the thing with Maven, it is quite simple. Download the requisite jar. Copy it at [your directory structure]\apache-maven-3.0.4\lib\ext. And that's it. You are all set. Start using Maven the way you have always done.
A humble request to Maven guys – we all know what an awesome job you have done and continue to do. Guess it is only normal to have a couple of bugs like this slip through. However, it has been there for six months now. Fix it please. I have been a passionate evangelist of this software and it helps my job if things like this do not linger on.
