* Allow project dependency to use runtimeClasspath
Project dependency should use runtimeClasspath. However, if
left unspecified, it uses 'default', which is the same as
the legacy 'runtime' configuration. (runtimeOnly dependencies
are left out).
Since runtimeClasspath cannot be referenced directly, we use
a custom config (deploy_jar) as a proxy.
By excluding testjars (leaked into 'compile' by third-party
dependencies) from runtimeClasspath, we prevent them from
getting into release artifacts.
Two meaningful changes in appengine_war.gradle and java_common.gradle
TESTED=Diffed contents of services/{module}/build/exploded-*
Only three jars are removed: hamcrest-core, junit, and
mockito-core.
* Break circular dependency between core and util
Created a new :common project and moved a minimum
number of classes to break the circular dependency
between the two projects. This gets rid of the
gradle lint dependency warnings.
Also separated api classes and testing helpers into
separate source sets in :common so that testing
classes may be restricted to test configurations.
