Subject [jira] [Commented] (SUREFIRE-1531) Option to switch-off Java 9 modules
Date Sun, 01 Jul 2018 18:46:00 GMT


Lukáš Křečan commented on SUREFIRE-1531:

Ok, if I should generalize the use case it's this:

In tests, I use additional dependencies. Some of them (like Mockito) use reflection or code
generation that needs access (opens or sometimes even exports) to potentially all dependencies
of the main module.

IntelliJ currently executes tests with classpath - not sure if it's a bug or feature

>          Components: Maven Surefire Plugin

>            Reporter: Lukáš Křečan
>            Priority: Major
> I am working on a library and I am adding support for Java 9 modules. Surefire 2.21.0
by default executes tests with Java 9 modules switched-on if it detects While
it may make sense in some cases, in my case I'd like the switch it off.
> The reason is simple. I am using Mockito to mock an interface that extends a Spring interface.
Mockito has to create an implementation of this interface (proxy or subclass) and for this
it needs to have access to the Spring interfaces. If Java 9 modules are enabled for the tests
I have to manually add each such dependencies to Surefire configuration, which does not make
much sense. To makes things worse, the interface actually extends two Spring interfaces form
two different Spring modules so the configuration is almost impossible to get right.
> So far I am at ( and I am still getting IllegalAccessErrors)
> {code:java}
> --add-exports spring.context/org.springframework.scheduling=org.mockito
> --add-exports spring.beans/org.springframework.beans.factory=org.mockito
> {code}
> I would prefer to switch-off the Java 9 modules for the test module altogether (same
behavior as pre 2.21.0)
> The test is here []
> If you want, I can send a pull request.
