运行Arquillian Chameleon测试时Snakeyml异常

Question

When running a test using Arquillian Chameleon in Windows, I get the following exception:

java.lang.IllegalStateException: Could not setup chameleon container
Caused by: java.lang.ClassNotFoundException: org.yaml.snakeyaml.constructor.Constructor

How can I fix this?

Answer 1

I'm answering this one myself because it was a simple fix to an odd problem.

I have Windows 10, and was running Maven from the WLS Bash shell. Under bash, Maven worked great and the tests ran as expected. But when I ran the tests in Powershell or from an IDE like IntelliJ, I got that exception.

The solution was to do a mvn clean , after which I could run the tests in Windows again. Obviously there is some incompatibility between files created under a Bash shell and those used in a Windows environment, so you can't just swap between the two.
