How to compile hibernate project with maven?

Question

I am novice to maven (as well as to hibernate) but want to learn both. I have downloaded a sample project from hibernate.org and now trying to compile it with maven but getting following error:

[INFO] Scanning for projects...

Looks it is trying to download libraries from the web? can I not provide all jars required by my sample project on local drive? Is there any quick solution of my problem, to start with? or I should study maven and hibernate in details before I start it?

Answer 1

Hibernate 3.5.2-Final is not available in the Maven central repository but is available in JBoss repository. So add the following to your pom.xml (or your settings.xml):

<repositories>
  <repository>
    <id>jboss-public-repository-group</id>
    <name>JBoss Public Repository Group</name>
    <url>http://repository.jboss.org/nexus/content/groups/public&lt;/url&gt;
  </repository>
  ...
</repositories>

I should study maven and hibernate in details before I start it?

Yes. Maven can be simple, or extremely complex depending on how far you want to go with it. Hibernate can be complex to set up if you're doing more than the basics. I'd suggest learning one at a time.

Looks it is trying to download libraries from the web? can I not provide all jars required by my sample project on local drive?

Yes and Yes. By default (I believe) maven both looks on your local filesystem and out on the interwebs. It attempts to keep your local copy in sync. But you can set it up to just use your local repository if you'd like.

Is there any quick solution of my problem, to start with?

Maybe. Change the version number from 3.5.2-Final to 3.3.2.GA for hibernate-parent.
