// Notes:
// - To compute the XWiki sha256, download the XWiki WAR from
//   http://nexus.xwiki.org/nexus/content/groups/public/org/xwiki/platform/xwiki-platform-distribution-war, and issue:
//   - Unix: sha256sum <binary name>
//   - Mac: shasum --algorithm 256 <binary name>
// - To compute the mysql JDBC sha256, get the JAR at https://search.maven.org/artifact/com.mysql/mysql-connector-j and
//   do the same as for the XWiki sha256.
// - To compute the MariaDB JDBC sha256, get the JAR at
//   https://search.maven.org/artifact/org.mariadb.jdbc/mariadb-java-client and  do the same as for the XWiki sha256.
// - To compute the Postgres JDBC sha256, get the JAR at
//   https://search.maven.org/artifact/org.postgresql/postgresql and do the same as for the XWiki sha256.
// - Use the JDBC driver versions found in the XWiki POM for the specified versions:
//   - mysql: https://github.com/xwiki/xwiki-platform/blob/master/pom.xml#L110 (link for master)
//   - mariadb: https://github.com/xwiki/xwiki-platform/blob/master/pom.xml#L113 (link for master)
//   - postgresql: https://github.com/xwiki/xwiki-platform/blob/master/pom.xml#L119 (link for master)
