/*
 * This script supports some Gradle project properties:
 *
 * - versionSuffix: appended to snapshot version number, e.g. "1.2.3-<versionSuffix>-SNAPSHOT".
 * Use to create different versions based on branch/tag.
 * - sonatypeUsername: Maven Central credential used by Nexus publishing.
 * - sonatypePassword: Maven Central credential used by Nexus publishing.
 *
 * This script supports the following environment variables:
 *
 * - OBX_RELEASE: If set to "true" builds and depends on release versions, without branch name and snapshot suffix.
