Following the change to build with a Jigsaw-aware JDK, an incremental build of WebKit native library no longer works. If you make a change in a native source code file and build with:

gradle -PCOMPILE_WEBKIT=true

The :web:compileNativeXxxxx task is not run and the library is not rebuilt.

To reproduce:

1. Compile with:

gradle -PCOMPILE_WEBKIT=true


2. change a file, for example, modules/javafx.web/src/main/native/Source/WebCore/platform/java/WebPage.cpp, to add a print statement.


3. Compile again with:

gradle -PCOMPILE_WEBKIT=true

Note that :web:compileNativeXxxx is listed as up to date


4. Run a test program and note that your print statement doesn't show up.
