Here's a one-liner (well, two) that neatly lists all the Maven dependencies from your project. Useful to check their licenses, for example.

# first grab all dependencies mvn dependency:resolve

then list them with -o to keep noise low,

remove extra information and duplicates

mvn -o dependency:list \ | grep ":.*:.*:.*" \ | cut -d] -f2- \ | sed 's/:[a-z]*$//g' \ | sort -u

The output looks like this:

asm:asm:jar:1.5.3 asm:asm:jar:3.1 biz.aQute:bnd:jar:0.0.169 cglib:cglib:jar:2.1_3 classworlds:classworlds:jar:1.1 classworlds:classworlds:jar:1.1-alpha-2 ...

so it's also useful to detect multiple versions of the same dependency in a multi-module project.
