We have a src/main class called UseJacksonForJsonPathRule which uses
classes from this dependency in geode-junit/build.gradle:
compile('com.jayway.jsonpath:json-path')
I'm trying to write a unit test in src/test called
UseJacksonForJsonPathRuleTest but it fails with the following
NoClassDefFoundErrors. These are the same classes used by any test using
UseJacksonForJsonPathRule. geode-dunit's
DistributedUseJacksonForJsonPathRule extends UseJacksonForJsonPathRule and
we have one test in geode-core that uses the distributed version of the
rule and it passes without NoClassDefFoundErrors.
Anyone know why or what needs to change in geode-junit/build.gradle?
Also, I seem to keep hitting this ever since we exploded geode-junit and
geode-dunit. It's as if the classpaths aren't really correct for
geode-junit and geode-dunit, such that when I start writing unit tests or
integration tests within those two modules, they just don't work unless I
move the test to geode-core -- that's the only module in which I can
actually run these back filled unit tests. Given that it seems to be a
systemic problem with geode-junit and geode-dunit, can we do something to
fix this systemically instead of every single time I write a new test?
