I do use Groovy and Gradle with Camel.
I haven't used the uber-jar with Gradle though, I am using the fatjar
plugin instead - https://github.com/musketyr/gradle-fatjar-plugin
You didn't provide any information about which versions you are using, for
instance in Camel the ".process { closure }" works since 2.11 and not
before.
(If you try it in earlier versions you get a groovy missing method
exception.)
It would help seeing a log printout, you say that you get all the logging
messages you expect except that you get the ExecResult.toString() instead
of the expected XML string, but it would be much easier to try help you if
I (we) can see what happens.
