Copy the media you would like to edit from the source into your overlay project, example:
No Format wget https://source.jasig.org/sa/sched-assist/trunk/sched-assist-war/src/main/webapp/themes/jasig/css/main_one_column.css /path/to/your/my-sched-assist-war/src/main/webapp/themes/jasig/css/main_one_column.css
- Pay close attention to the paths - remember that overlays work by "overlaying" your content on top of the original artifact. If your path doesn't match the path in the original source, you won't overwrite the desired file.
Execute the following command within your my-sched-assist-war directory to rebuild your war:
No Format mvn clean package
Redeploy the war to Tomcat. You will likely need to "shift+refresh" in your browser to force download of the new content.
