IntelliJ IDEA 2016.2.5 dependency resolution problem with Grails 3 multiproject

Hi,
I've have a Grails 3 multiproject (see attached files) structured as a plugin project (myplugin) and an app project (myapp).
In myplugin I set all my dependencies like external libraries and Grails third party plugin.
Everything works fine except that IntelliJ can not resolve classes contained in the third party plugins.

See TestController of myapp project in the attached files, in action detect (TestController.groovy line 19) IntelliJ can not resolve UserAgentIdentService that is a service
of plugin 'org.grails.plugins:browser-detection:3.3.0' but the code runs without errors either in IntelliJ debug either in 'grails run-app'.

Same problem in the associated view (detect.gsp) IntelliJ cannot resolve Tablib <browser:...>.

System info:
OS Linux Mint 18
IntelliJ IDEA 2016.2.5
Environment: development
App profile: web
Grails version: 3.2.3
Groovy version: 2.4.7
JVM version: 1.8.0_111

Start by reproducing the attached Grails 3 multiproject in IntelliJ IDEA and compare its project model with grails run-app. Inspect TestController.groovy line 19 and detect.gsp, where the browser-detection plugin service and taglib are unresolved. Done means IntelliJ resolves UserAgentIdentService and the taglib while runtime behavior remains unchanged.
