Grails 3.2.2: Interceptor not executed

[itpragmatik]

Steps to Reproduce

1. install grails 3.2.2
2. grails -v to confirm i am running 3.2.2
3. grails create-app myapp
4. add an interceptor myapp/grails-app/controllers/myapp/AuthenticationInterceptor.groovy
5. grails clean && grails war
6. java -jar -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005 build/libs/myapp.war
7. From my IntelliJ IDEA, set a breakpoint in the before() method of AuthenticationInterceptor
8. Start debug from IDE
9. Access http://localhost:8080/

Expected Behaviour

1. Execution suspends at the breakpoint

Actual Behaviour

1. Grails default index.html welcome page is shown; interceptor breakpoint is not hit.

I can't reproduce this problem.

How are you launching the project from within the IDE?

[jeffscottbrown]

I am using IntelliJ IDEA 2016.2.4

My mistake. I see now that you are running with java -jar.... I had overlooked that. Sorry for the noise.

I can confirm this as I just ran into this problem. Interceptors will not run when running with java -jar
Happens in Grails 3.2.0 and Grails 3.2.2

I've have not tried to deploy the war file on a Tomcat server yet.

grails-app/conf/BootStrap.groovy seems to suffer the same problem, not executed when running with java -jar since Grails 3.2.0.

I looked at the grails.factories for the interceptor plugin that was bundled with the war and it contained:

grails.compiler.traits.TraitInjector=grails.compiler.traits.InterceptorTraitInjector
grails.core.ArtefactHandler=org.grails.plugins.web.interceptors.InterceptorArtefactHandler

When the classloader gets the factories, the result of url.text for the interceptor grails.factories is:

#Grails Factories File
#Thu Oct 27 15:24:17 UTC 2016
grails.compiler.traits.TraitInjector=grails.compiler.traits.InterceptorTraitInjector

So something is not being read correctly. I verified the URL path was the same path of the file I inspected.

Workaround is to use grails-plugin-interceptor from 3.2.1 for the moment:

compile "org.grails:grails-plugin-interceptors:3.2.1"
