WRO4J in ANT

[yudi...@gmail.com]

I am trying to use wro4j in ANT build to precompile handlebars templates to js. I searched online and find this. It announces that it will allow you to use wro4j in ant.

Can anyone help me with this ? Alex? I am really confused. There is an wro.xml file in my WEB-INF directory.

[Alex Objelean]

You are using wro4j-runner which by default expects to find the model in the current working directory, unless a different location is configured explicitely.

Let me know if you manage to solve this.

Cheers,
Alex
