*  Fix: Retry automatically when incorrectly sharing a connection among multiple hostnames. OkHttp
    shares connections when hosts share both IP addresses and certificates, such as `squareup.com`
    and `www.squareup.com`. If a server refuses such sharing it will return HTTP 421 and OkHttp will
    automatically retry on an unshared connection.
 *  Fix: Don't crash if a TLS tunnel's response body is truncated.

Subprojects in a multi-project build typically share some common dependencies.

Instead of copying and pasting the same Java version and libraries in each subproject build script, Gradle provides a special directory for storing shared build logic that can be automatically applied to subprojects.

// On Windows, Clean does not modify the volume name other than to replace
// occurrences of "/" with `\`.
// For example, Clean("//host/share/../x") returns `\\host\share\x`.

As such, this is a perfect tool whenever you need to _share dependency versions between projects_.
In this case, a project will typically be organized this way:

- a `platform` project which defines constraints for the various dependencies found in the different sub-projects

// - GCE PD allows multiple mounts as long as they're all read-only
// - AWS EBS forbids any two pods mounting the same volume ID
// - Ceph RBD forbids if any two pods share at least same monitor, and match pool and image, and the image is read-only
// - ISCSI forbids if any two pods share at least same IQN and ISCSI volume is read-only
// If the pod uses PVCs with the ReadWriteOncePod access mode, it evaluates if
