+1 on this from me. I have a very large project with a large number of
dependencies and just the size of the file makes things more
complicated than it could be.
Is seems to be that expressing having fewer characters that same
exactly the same thing would make large files much simpler.

After seeing what the Spring Developers have done to simplify Spring
context files, I can't help but think the same thing is possible for
Maven 2's pom.xml. Is it possible to add namespaces and make
something like the following possible?
Before:
<dependency>
<groupId>springframework</groupId>
<artifactId>spring</artifactId>
<version>1.2.6</version>
</dependency>
After:
<dep:artifact name="org/springframework/spring" version="1.2.6"/>
Or just allow attributes to make things a bit cleaner?
<dependency groupId="org.springframework" artifactId="spring"
version="1.2.6"/>
Allowing 1 line instead of 5-6 lines per dependency would allow me to
cut my dependencies listing from 140 lines of XML to 37 lines. When
the Spring guys allows a couple of elements as attributes (<ref> and
<value>) - it made writing Spring context files *much* easier.
Here's an example of my simplified version:
<dependencies>
<dependency groupId="cargo" artifactId="cargo" version="0.6"
scope="test"/>
<dependency groupId="commons-lang" artifactId="commons-lang"
version="2.0"/>
<dependency groupId="commons-logging" artifactId="commons-logging"
version="1.0.4"/>
<dependency groupId="displaytag" artifactId="displaytag"
version="1.0" scope="runtime">
<exclusions>
<exclusion artifactId="xalan" groupId="xalan"/>
</exclusions>
</dependency>
<dependency groupId="uk.ltd.getahead" artifactId="dwr"
version="1.0" scope="runtime"/>
<dependency groupId="org.hibernate" artifactId="hibernate"
version="3.0.5">
<exclusions>
<exclusion artifactId="jta" groupId="javax.transaction"/>
</exclusions>
</dependency>
<dependency groupId="geronimo-spec" artifactId="geronimo-spec-jta"
version="1.0.1B-rc4"/>
<dependency groupId="jmock" artifactId="jmock" version="1.0.1"
scope="test"/>
<dependency groupId="junit" artifactId="junit" version="3.8.1"
scope="test"/>
<dependency groupId="jwebunit" artifactId="jwebunit" version="1.2"
scope="test"/>
<dependency groupId="httpunit" artifactId="httpunit" version="1.6"
scope="test">
<exclusions>
<exclusion artifactId="js" groupId="rhino"/>
</exclusions>
</dependency>
<dependency groupId="log4j" artifactId="log4j" version="1.2.11"/>
<dependency groupId="postgresql" artifactId="postgresql"
version="8.1-404.jdbc3"/>
<dependency groupId="javax.servlet" artifactId="servlet-api"
version="2.4" scope="provided"/>
<dependency groupId="javax.servlet" artifactId="jstl"
version="1.1.2" scope="runtime"/>
<dependency groupId="taglibs" artifactId="standard"
version="1.1.2" scope="runtime"/>
<dependency groupId="opensymphony" artifactId="sitemesh"
version="2.2.1" scope="runtime"/>
<dependency groupId="springmodules"
artifactId="springmodules-validator" version="0.1" scope="runtime"/>
<dependency groupId="springframework" artifactId="spring"
version="1.2.6"/>
<dependency groupId="springframework" artifactId="spring-mock"
version="1.2.6" scope="test">
<exclusions>
<exclusion artifactId="spring-jdbc" groupId="springframework"/>
<exclusion artifactId="spring-web" groupId="springframework"/>
</exclusions>
</dependency>
</dependencies>
Of course, Ivy's syntax is even simpler, so maybe that'll provide some
motivation. ;-)
<dependencies>
<dependency org="apache" name="commons-lang" rev="2.0" />
<dependency org="apache" name="commons-cli" rev="1.0" />
</dependencies>
