Eclipse Automatically Download / Update JAR files

I just created a Web App project from a repository through Eclipse's SVN support. What I would be doing is have an ANT build going and then finally deploy through Tomcat.

I am using Eclipse IDE for Java EE developers on an Ubuntu system.

There are a num开发者_如何转开发ber of jar files needed to support my project - like Struts, Hibernate, etc. etc.

Do I need to

manually download each of them

and put them in the lib folder?

OR

Does Eclipse have a solution to automatically UPDATE these from the internet? Any plugins to automatically take care of this?

You should consider using Maven for your project. It's VERY well supported in Eclipse, and handles all dependencies (as well as other things, such as releases).

The problem is there's a bit of a learning curve, but if you intend your project to get to a considerable size, I'd say it's very important.

Maven has support for ant builds and most libraries are in the central Maven repository. You just say your project has a dependency on the external project and it will automatically download the dependencies.
