Getting java.lang.NoClassDefFoundError: org/eclipse/jetty/util/thread/ThreadPool when trying to run

[Indranil Banerjee]

Hi,

I created a simple Junit test to mock a response and verify the response is correct.

I used Wiremock standalone to capture the actual request sent by ElasticSearch.

Now I am trying to run the Junit test to make the same query to Wiremock instead of ElasticSearch.

When I run the test, I am getting the following exception. I am using Wiremock 2.1.11. Looks like the dependency mapping is not pulling in the dependencies correctly

Ran into this with a Spring boot app and this works (versions managed by boot).  Actual version for these is 9.3.14.v20161028
