This commit configures the Kotlin plugin for Eclipse in the
spring-core-coroutines Gradle project so that users no longer have to
manually "Configure Kotlin / Add Kotlin Nature" within the Eclipse IDE
after importing projects.
This change is currently limited to the spring-core-coroutines project
since it is the only project in which Java code depends on compiled
Kotlin code; however, this change may later be applied to additional
projects if desirable.
This commit introduces the spring-core-coroutines module
in order to avoid referencing Kotlin code from Java one,
which is currently not supported by Eclipse.
During the build, spring-core-coroutines is merged into
spring-core, so this change is expected to have no impact
for end users.
This module contains functions accessible from Java via
the CoroutinesUtils class to adapt Coroutines and Deferred
instances to and from Mono.
