Managed to fix it.
A project dependency was requiring guava 18.0, but jenkis-core was fetching
11.0.1. To fix it I had to exclude guava from jenkins-core:
<dependency>
<groupId>org.jenkins-ci.main</groupId>
<artifactId>jenkins-core</artifactId>
<exclusions>
<exclusion>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
</exclusion>
</exclusions>
<scope>provided</scope>
</dependency>

Subject: Need help configuring the pom.xml so I can have integration tests
Hi,
I’m trying to add integration tests in my plugin and I want them to be optional
and only be triggered if you run a specific maven step.
To accomplish this I added a dependency to the maven failsafe plugin and now I
need to run “mvn failsafe:integration-test” to run my specific integration
tests.
So far so good, but when I need to execute some code that depends on jenkins
I’m getting NoClassDefFoundError exceptions. I managed to fix some of these by
adding a dependency to the jenkins-test-harness, but now I’m hitting one I
can’t fix: “java.lang.NoClassDefFoundError:
com/google/common/reflect/TypeToken”. The exception is due to the fact that I
don’t have a direct dependency to google guava, but the jenkins-core should
bring that into my classpath, but even if I add the jenkins-core as a
dependency within the “test” scope I can’t manage to fix it.
Here’s the pom file portion in question:
<dependency>
<groupId>org.jenkins-ci.main</groupId>
<artifactId>jenkins-test-harness</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.jenkins-ci.main</groupId>
<artifactId>jenkins-core</artifactId>
<scope>provided</scope>
</dependency>
I’m using “provided” scope right now because that’s what Maven recommends:
https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#Dependency_Scope<https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fmaven.apache.org%2Fguides%2Fintroduction%2Fintroduction-to-dependency-mechanism.html%23Dependency_Scope&data=02%7C01%7Cclguiman%40microsoft.com%7C32bf7fe0fb5d445ede3308d438b584f3%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C636195799650561529&sdata=U4tMOQTiEt1pOCiCRlKlVIJD8xElcsN63UF5Fydnvvk%3D&reserved=0>
Can someone help me understand what I’m doing wrong and how I should fix the
pom file?
Thanks,
Claudiu
