== Creating packages

To create a distribution without running the tests, simply run the
following:

-----------------------------
./gradlew assemble
-----------------------------

To create a platform-specific build including the x-pack modules, use the
following depending on your operating system:

-----------------------------
./gradlew :distribution:archives:linux-tar:assemble
