Pax Exam + Karaf + Conditional Packages
Hello,
I want to test an OSGi bundle built with bnd using conditional-packages via
pax-exam. The conditional-package allows the bundle to use some utility
classes (e.g., like from https://stackoverflow.com/a/39500621/1887602)
The test is setup like the following:
@Test
public void exampleTest() {
UtilityClass.foo(this.wiredService)
}
where:
- wiredService is a service which has been injected via @javax.Inject;
- UtilityClass is the class which has been bundled in the jar with the
conditional-package.
The test container I'm using is Karaf.
When testing the application, Osgi alerts me that it cannot find the class
"x.y.z.UtilityClass".
So my question is: how can I retrieve conditional-package classes using
pax-exam?
Here's the (anonymized) stack trace:
java.lang.ClassNotFoundException: x.y.z.UtilityClass not found by

Thanks for any kind reply
Re: Pax Exam + Karaf + Conditional Packages
Posted by Massimo Bono <ma...@gmail.com>.
Ok,
I've solve my issue (using a really naive solution). With maven I've
created a bundle out of all the classes which were in the
conditional-package BND instruction. Then I've simply added the newly
created bundle within the @Configuration Pax-Exam method.
Maybe it's not the best solution, but works.
