Last week I wrote about writing JUnit tests with accurate exception matching. That relies on the Hamcrest library to work. Unfortunately the JUnit Maven artefact uses only the hamcrest-core dependency which leads to some compilation errors like this...


The dependency tree from Maven shows up like this...


As expected, but incomplete. After checking the Hamcrest Distributables page it becomes clear that the hamcrest-core is the bare minimum dependency and doesn't include the required matchers and supporting classes. What's required is the hamcrest-library dependency. This is easily resolved, just add this to your pom.xml file...


The dependency tree now looks like this and all of the compilation errors are fixed!
