Description
Currently the size of the app-layout-addon-4.0.0-RC5.jar is about 5.4 MB and the version 4.0.0 (final) jar is 2.5 MB . This is both quite huge in my opinion and the difference is also quite huge.
I suspect there are build artifacts packaged into the final jar that are not necessary for the addon.
The 4.0.0 jar file contains a file /META-INF/VAADIN/config/stats.json which is 1.9 MB (uncompressed) . The RC5 version of this file is 26.7 MB (uncompressed). From looking at the contents of the file I suspect this one is not necessary in the final jar file.
There is also the /META-INF/VAADIN/build/ folder that contains 6 MB (uncompressed) of javascript files and there gzipped versions. I didn't write a Vaadin 14+ addon myself thus I cannot tell whether those files are necessary or not. Could you check what is really necessary there?
