Cannot run a simple JerseyTest unit test example - unit-testing

Question

I'm trying to add unit testing of ReST calls using JerseyTest framework in my project. I've copy-pasted a most trivial example, but I get a run-time exception:
java.lang.NoSuchMethodError: javax.ws.rs.core.Application.getProperties()Ljava/util/Map;

Answer 1

As already said, this error is due to a conflict in your dependencies (probably between jersey 1 and 2). More information here. In fact, you use the version 1.18 of jersey-server, and other versions 2.6 in your pom.xml.

Answer 2

Solved by removing jersey-server and jersey-all dependencies, updating jersey dependencies to the latest version (2.15) and adding jetty dependencies.

Answer 3

I had the same issue
I was getting this library transitively:
org.glassfish.jersey.media:jersey-media-json-jackson:jar:2.14
All of my jersey libs where version 2.6, excluding the above made my test cases pass. I add this:
<exclusion>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-json-jackson</artifactId>
</exclusion>
</exclusions>
