List all your Maven dependencies

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.

    The dependency convergence report would also give you a nice HTML page that points out multiple versions of the same dependency in a multi-module project, and the licenses :)

    I have a maven project which have modules(OSGi bundles) inside it.
    I have to write list of dependencies(no duplicates) from all of these modules in a file while building from top level POM file.
    Can you pls suggest how to do this?

    I have tried following but dependencies are not listed in the created file:

    org.apache.maven.plugins
    maven-dependency-plugin

    list-dependencies
    generate-sources

    resolve

    target/dependencies.list

    Best Regards,
    Amit
