+Introduction

+The WritePom Task
+
+ <<Note: This task is available since version 2.1.0>>
+
+ The WritePom task can be used to generate a POM file based on information defined in
+ the Ant build. For example, this could be used to generate a POM used when
+ deploying build artifacts to a Maven repository.
+
+ The first step is to define a pom using the pom task.

+
+ The next step is to call the writePom task using the pom id created above.

+ <artifact:writepom pomRefId="mypom1" file="target/mypom1.xml"/>

+ This will generate a pom in the location specified.
