gradle - "Incremental java compilation is an incubating feature." takes too long for every cordova build Process -

every time build cordova project, build process stuck 8 minutes.
last line in log when happens : incremental java compilation incubating feature.

has seen happen before?

i'm using visual studio 2015 , running on windows 10 build 14393.10.

my question why build proccess takes long?

update:

here build logs:
