java.lang.AbstractMethodError/ClassCastException when creating integration test for osgi using felix and PaxRunner Framework [PAXRUNNER-443]

[ops4j-issues]

Aldrin Tingson created PAXRUNNER-443

I am trying to create integration test for my bundle. basically I want to mimic the setup I have in normal web app project(wherein the test are in src/test folder)

I am almost there except that I have exception when the bundle tries to activate

native container exception

Can someone expert help me with my problem? I am at the end of my ropes already :slightly_frowning_face:

Sample Project(If the project file does not work just tell me):

git clone git@bitbucket.org:aldrintingson/cq-training.git

commands:

mvn clean verify

Fix propsed:
1. Make sure that org.osgi.core has a provided scope

in the parent project it is provided already, plus i tried explicitly specifying it in pom.xml of the bundle(core folder) and still no avail.

2. Create a package first of the project then bundle then add it to bundles during the Configuration phase

did the following steps:

a. uncommented out this line of code in HelloWorldServiceImplIntegrationTest.java
//bundle("file:target/cq-training-core-1.0-SNAPSHOT.jar"),

b. mvn clean package -DskipTests
c. mvn verify

same error

Thanks

Here's what I see:

Here's my relevant dependency:

org.osgi:org.osgi.core:jar:5.0.0:provided

Here's my test setup. The bundles in here include nothing from pax, it's all my stuff.

 return options(
                provision(bundles),
                // add in the root when we are using the root case.
                when(useRootFragment()).useOptions(url(String.format("file:%s/rbl-osgi-%s-fragment-bundle.jar", projectBuildDirectory, projectVersion)).noStart()),
                systemPackages(
                        // These are needed for guava.
                        "sun.misc",
                        "javax.annotation",
                        // actually used in RBL; perhaps we need to eliminate?
                        "javax.swing.text",
                        //
                        String.format("org.slf4j;version=\"%s\"", getDependencyVersion("org.slf4j", "slf4j-api"))

                ),
                junitBundles(),
                systemProperty("org.ops4j.pax.logging.DefaultServiceLog.level").value("WARN")
        );
