RE: Problems with the maven-failsafe-plugin and loading of resources from (test-)jars

[Christofer Dutz]

As usual,

as soon as I take the time to write the email, I seem to find a solution 
shortly after that ...

So, it seems that I managed to load the resource by changing:

this.testsuiteDocumentXml = getClass().getResourceAsStream(testsuiteDocument);

To:

this.testsuiteDocumentXml = 
getClass().getClassLoader().getUnnamedModule().getResourceAsStream(testsuiteDocument);

I think this is probably just a workaround and I am not quite sure about the 
implications. 

So, it this the way to go, or is there a prettier way to fix this?

Sorry for the double posting ... guess my mailserver had hickups and now I know 
why I had to write it twice 😉

I think this version might be the better one ..

Hi,

in the Apache PLC4X build we recently noticed that surefire and failsafe 2.22.2 
were missing to pickup some of our tests, which we use with @TestFactory 
annotation.
It turns out that when switching to 3.0.0-M5 this problem is resolved.

However, a new problem is now causing problems.

In our tests we usually load test-jars which contain test-resources which are 
processed in our tests.

They are referenced by the module in this way:

    <dependency>
      <groupId>org.apache.plc4x</groupId>
      <artifactId>plc4x-protocols-modbus</artifactId>
      <version>0.10.0-SNAPSHOT</version>
      <classifier>tests</classifier>
      <type>test-jar</type>
      <scope>test</scope>
    </dependency>

In failsafe the test is unable to load the resources. If I run the identical 
test in surefire, it works. If I run it in failsafe 2.22.2, it works.
In the IDE the tests also work fine.

So, I did some debugging and could see that the classloader used to load the 
resources correctly contains the jar that contains the resources in its 
URLClassPath, however the Classloader doesn't seem to use this.

Anyone got an idea what's going on?

Thanks,
Chris
