Could not initialize class org.apache.sling.testing.mock.osgi.MockEventAdmin

Level 2

Hello,

 

We are on AEM 6.4.8 and starting to setup unit test cases.

I have followed the article: 

https://experienceleague.adobe.com/docs/experience-manager-learn/getting-started-wknd-tutorial-devel...

 

I have added all dependencies as mentioned in the article, but when trying to run the test, getting the following error:

 

java.lang.NoClassDefFoundError: Could not initialize class org.apache.sling.testing.mock.osgi.MockEventAdmin

Any help will be appreciated.

 

Thanks

Hi @ruchim71073425 

Can you please add the following maven dependency and retry?

<!-- https://mvnrepository.com/artifact/org.apache.sling/org.apache.sling.testing.osgi-mock.junit5 -->
<dependency>
<groupId>org.apache.sling</groupId>
<artifactId>org.apache.sling.testing.osgi-mock.junit5</artifactId>

Assuming you're on jdk8, I might have had a similar issue in the past. It was specific to my local machine since our pipelines were running fine. 

 

Then realized that a system update had reset some env variables and my java home was reset to jdk11 which was subsequently getting picked up by mvn

The tests started running fine was the env variables were reset and mvn picked up jdk 8 as the version being used. 

 

$ mvn -version
