How to resolve some dependencies while building the project through Maven?

Question

I have some Java projects with me and I am trying to build it using Maven in Windows. But I am getting certain errors while doing it. I have used the command as

"mvn -Dmaven.test.skip=true install" 

The details is as:

I want to just ask that how to resolve dependencies if I am getting certain issues. I don't know much about the maven and hence stuck with such problems

Please advice.

Thanks

Answer 1

You're having this problem because your local machine cannot connect to the main maven repository at this location: http://repo1.maven.org/maven2. It's likely you need to configure your maven proxy settings http://maven.apache.org/guides/mini/guide-proxies.html.

Answer 2

In addition, instead of downloading artifacts from Central, try to set up your own "enterprise repository".

• This will lighten the load of this server
• This will lighten the load your enterprise internet bandwidht (mine is very very limited ;)
• You will manage to delpoy you own artifact on.

This only need ... well, a server (physical or virtual) and a tomcat. You should read this free book : http://www.sonatype.com/books/mvnref-book/reference/

The main products are :

• Artifactory :http://www.jfrog.com/products.php
• Nexus : http://www.sonatype.org/nexus/ ...

This is not very difficult, although it appears to be annoying when you thought you just had to install maven, make your pom and go on :)
