Description

Please re-add "mvn dependency:tree -Dverbose".

Ticket Bounty: 300USD (will send via PayPal to address of authors choice upon feature re-addition with proper Maven 3 support)

I find the command to be really useful and use it daily to check for transitive dependency clashes.

It seems the command was removed in maven-dependency-plugin:2.11 because it used an outdated version of the dependency resolution mechanism?

As a workaround I currently invoke the command like this:
mvn org.apache.maven.plugins:maven-dependency-plugin:2.10:tree -Dverbose

It's so useful I even added some colorization in bash:

 

function mdt() {
    mvn org.apache.maven.plugins:maven-dependency-plugin:2.10:tree -Dverbose $@ \
        | GREP_COLOR='01;31' grep --color=always -E 'omitted for conflict with|$' \
        | GREP_COLOR='01;31' grep --color=always -E 'version managed from|$' \
        | GREP_COLOR='01;32' grep --color=always -E 'omitted for duplicate|$' \
        | GREP_COLOR='01;35' grep --color=always -E ':test|$'
}

I execute this command every time I wonder if I messed up any transitive dependencies. It's a really good and quick sanity check command, and I think there's a strong user case for it.

Sadly the workaround I use is an incorrect one. It will lie. The proper solution is probably to readd the feature with the new Aether resolution mechanism (Maven 3)?
