For the sake of documentation, note that "groupID" should be "groupId".
1) groupID is described as "The project group that produced the
dependency, e.g. geronimo." I tried "spring" which failed, and then
"springframework" which worked. I surmise that the project group
corresponds to the directory name "springframework" in:
http://www.ibiblio.org/maven/springframework/jars/ . I might be nice
if
the description included a blurb saying something about each group
having it's own directory - or some such. It was a minor leap to
realize that the project group is typified by the directory ;)
Unfortunately, the groupId is not always obvious. Sometimes there's
even confusion -- on iBiblio, for instance, there are directories named
"spring" and "springframework". The only reliable thing to do (that I'm
aware of) is point your browser to <http://www.ibiblio.org/maven/> and
go looking for the JAR file in which you're interested.
2) artifactId is described as "The unique id for an artifact produced
by
the project group, e.g. germonimo-jms." I tried springframework first,
and when I saw the command window say "Attempting to download
springframework-1.2.2.jar" I knew what to do.
This should be documented somewhere -- both in the sense of "it
probably is" and "if it's not, it should be":
Maven builds URLs to remote dependencies using the pattern
http://www.ibiblio.org/maven/${groupId}/${type}s/${artifactId}-
${version}.${type}
(This is a slight oversimplification, but is valid for a stock
installation of Maven.) So, given a dependency declaration like
<dependency>
<groupId>springframework</groupId>
<artifactId>spring</artifactId>
<type>jar</type>
<version>1.2.2</version>
<dependency>
Maven will build the URL
http://www.ibiblio.org/maven/springframework/jars/spring-1.2.2.jar
If the "type" element is omitted from the declaration, Maven assumes a
value of "jar".
