}

Execution

See Gradle Java tests for configuration information. In short:

Using Hamcrest

JUnit 4.11 and later

There is nothing extra that needs to be done in order to use a specific artifact of Hamcrest. In the past, there were two JUnit Maven artifacts: junit:junit and junit:junit-dep, where the latter version did not include a bundled copy of org.hamcrest:hamcrest-core and instead declared a transitive dependency on Hamcrest. In order to be more Maven-like, starting in version 4.11, there is only the junit:junit artifact which uses a transitive dependency on hamcrest-core.

JUnit 4.10 and earlier

Instead of using junit:junit as your test dependency, you should use junit:junit-dep along with specifying a particular Hamcrest library dependency beforehand. For example:

dependencies {
  testCompile group: 'org.hamcrest', name: 'hamcrest-core', version: '1.3'
  testCompile group: 'junit', name: 'junit-dep', version: '4.10'
  testCompile group: 'org.hamcrest', name: 'hamcrest-library', version: '1.3'
  testCompile group: 'org.mockito', name: 'mockito-core', version: '1.9.+'
}
