As Kevin mentioned you can't build it with webview-deps 1.2 (except may be for OSX where the new 
deps weren't changed).

On Linux webview-deps 1.3 additionally contain ICU 48 libs for static linking:

lib/
   libicudata.a
   libicui18n.a
   libicuio.a
   libicuuc.a

include/unicode/
   a list of related headers

You can take the sources from here and try to build them on your own:

Does it mean you found the missing ICU static libs in libqt4-dev?...

The sources in:

rt/modules/web/build/linux/Release/WebCore/generated/java

are copied from:

rt/modules/web/src/main/java-wrappers.

These sources depend on the main sources in: rt/modules/web/src/main/java.

The build process goes in the following order:

1. java sources: rt/modules/web/src/main/java
2. native sources: rt/modules/web/src/main/native
3. generated java sources: rt/modules/web/build/linux/Release/WebCore/generated/java

So, on the 3rd step all the main java compiled sources should already be put into:

rt/modules/web/build/classes/main

including the com.sun.webkit.Disposer class. So, please check you have it there.

Also, please make sure you have Gradle v1.8 as recommended on the wiki page.

In case you continue facing issues with the generated java sources, please send me the full build 
log file...

(Kevin already responded to this point.)


Thank you for the reporting problems!

With regards,
