Display a dependency tree on the console.

This is a link:../use/postresolvetask{outfilesuffix}[post resolve task], with all the behaviour and attributes common to all post resolve tasks.

Please prefer the use of retrieve + standard Ant path creation, which make your build more independent from Ivy (once artifacts are properly retrieved, Ivy is not required any more).

== Attributes

[options="header",cols="15%,50%,35%"]
|=======
|Attribute|Description|Required
|showEvicted|specify if evicted modules should be printed|No. Defaults to `false`
|conf|a comma separated list of the configurations to take in consideration in the  dependency tree|No. Defaults to the configurations resolved by the last resolve call, or `*` if no resolve was explicitly called
|haltonfailure|`true` to halt the build on Ivy failure, `false` to continue|No. Defaults to `true`
|validate|true to force Ivy files validation against ivy.xsd, false to force no validation|No. Defaults to default Ivy value (as configured in settings)
|settingsRef|A reference to Ivy settings that must be used by this task (*__since 2.0__*)|No, defaults to `ivy.instance`.
|overwrite|Overwrite the value of the property if it already exist (*__since 2.0__*).  Before 2.0, the properties were always overwritten.|No, `false` by default.
|=======

== Example

Suppose we have two dependencies one called __mydep__ in revision 2.0 and one called __myotherdependency__ in revision 2.2.
__mydep__ has a transitive dependency on __mytransitivedependency__ in revision 2.2.

Then:

[source,xml]
----
<dependencytree/>
----

will display the following tree in the console:

[source]
----
Dependency tree for foobar
+- org#mydep;2.0
   \- org#mytransitivedependency;2.2
\- org#myotherdependency;2.2");
----
