How to find out which dependencies need to be included?-Collection of common programming errors

Search for a maven dependency definition on the framework web site. If you can not find any dependency definition, them simply google for “frameworkname _version_ maven dependency” and you’ll most probably find necessary definition, as well as the necessary repository information. For example you can find the dependency definition for hibernate on mvnrepository.com and necessary artifact repository information on Hibernate 3.6.8 release page:

The artifacts have all been published to the JBoss Nexus repository under the org.hibernate groupId at http://repository.jboss.org/nexus/content/groups/public-jboss/

The question of which dependencies are necessary and which are optional depends entirely on the framework to be used. So for example in order to use hibernate, as stated on Hibernate Quick Start Guide:

hibernate-core: The main artifact, which contains all the Hibernate classes, in packageorg.hibernate. You need these to build applications using the native Hibernate APIs. It includes capabilities for using native Hibernate mapping in hbm.xml files, as well as annotations.

About compatibility issues (which version of hibernate is compatible with spring 3.0.6), all I can say is you have to read about integration manuals for those frameworks. Since Spring and Hibernate are two exclusively distinct frameworks, I don’t think you can find a constant location to look for version compatibility matrix or something like that.
