Good idea.
I just tried that, adding the following to the ide-dependencies task:
<!-- Extract META-INF from freemarker.jar and put it in base directory for
eclipse -->
<unzip src="build/freemarker.jar" dest=".">
<patternset>
<include name="META-INF/*"/>
</patternset>
</unzip>
And adding META-INF to .gitignore
