Description

The reasons I would like to use maven are:

• the possibility to define artifact templates to define a kind of standard layout/design by artifact
• it is not necessary for every developer to come up with his own ant build-file and process
• the possibility to define and resolve dependencies transitively

But there are also some disadvantages/concerns I identified:
Maven is downloading a lot of plugins from a central repository that is not under my control

• What's about the licenses of these plugins? How do I know I am allowed to use them for a commercial product?
• What's about security? How can I be sure, that the plugins are not manipulated and contain the original (delivered by the JAR provider for e.g. junit-jar) contents. I observed, that some plugins didn't pass the md5 checks but have been installed anyway.
