gwt-user-2.2.0 jar too large to upload to App Engine

[David Chandler]

It turns out that gwt-user-2.2.0 is just over the App Engine limit for a single file (10M) so you must enable jar splitting to deploy to GAE. There is no need to deploy gwt-user because it's only used for GWT compilation and dev mode, and the GWT Expenses sample POM correctly indicates <scope>provided</scope> to prevent this. However, the sample POM also says <copyWebapp>true</copyWebapp>, which copies src/main/webapp to target/proj_name in order for GWT dev mode (gwt:run) to work.

Possible fix is to modify <copyWebapp> feature of gwt-maven-plugin to exclude gwt-user-*.jar. Your thoughts?

If you're using a POM with <copyWebapp>true</copyWebapp>, you can include this bit of maven goodness to remove the gwt-user jar before GAE deployment.

Should <copyWebApp> exclude any <scope>provided</scope> dependencies?

[David Chandler]

Yes, I think that makes a lot of sense.
