Q: intelliJ Idea not generating cache.js files With IntelliJ 10.5.1 on Linux using GWT when selecting "Build 'xyz:GWT' artifact" it will often times just build the nnnn.cache.html files, but not the nnnn.cache.js files.  I've tried cleaning the cache, rebuilding the project, reloading IntelliJ but don't know what else to try.
This has happened before, but I don't know what fixed it afterwards.  Rebooting the system?

A: IDEA places files generated by GWT compiler to USER_HOME/.IntelliJIdea10/system/gwt/project_name_with_hash/module_name_with_hash/compile/www directory and then copies these files to the artifact output. So you can check whether that directory contains required files.

A: Try to add -war <path/to/your/war> to dev mode properties. It will put all compiled files to this folder.
