## README

This Maven plugin can help you answer the question "Where is this code coming from?"

It uses [BND](http://bnd.bndtools.org/) under the covers to reverse engineer the maven dependencies of a project.

It has two report modes, a tree mode and a flat mode.

By default it only shows exports but you can make it specify all package information

# Parameters

`-Dtype=[ tree | flat ]`

* the default is `tree` which humans can read better
* use `flat` if you want to grep for packages

`-Ddetail=[ exports | all ]`

* the default is `exports`
* `all` will show imports, exports, contained and referenced packages

`-verbose=[ true | false ]`

* the default is `false`


# Tree Mode

    mvn com.atlassian.maven:whence:whence -Ddetail=all -Dstyle=tree

produces output like :
