The good news is I was finally able to build my "Resources" SWC (containing images, stylesheets, and properties files that embed images) in Flexbuilder. The bad news is for my poor colleague who is gallantly doing the continuous integration work (with MSBuild and mxmlc/compc).
In Flexbuilder, I ended up with the following layout: resourcesproj ..locale ....en_US ......images.properties ..src ....images ......zoom.png ....com ..stylesheets ....myapp.css In Flexbuilder, I had the images checked on the Assets tab, and the following additional compiler options -locale en_US -source-path=../locale/{locale} -include-resource-bundles=images,UIStrings -include-file myapp.css ../stylesheets/myapp.css Is there really no wildcard way to include all the images in the SWC from the command line without listing them explicitly in a config file? I guess Flexbuilder builds a list based on the checkboxes in the Assets tab? The properties files references the images like this zoom=Embed("images/zoom.png") I assume we would have to use images/zoom.png as the name in a -include-file directive? Hoping for better error messages and CI support in Flexbuilder 4...
