title: Is OLAP4J dead and is there a replacement equivalent?
body: <p>Is OLAP4J (Java library for connecting to XMLA services) dead? The things that suggest it is are:</p>
  
  <ul>
  <li>The <a href="http://www.olap4j.org" rel="nofollow noreferrer">web site</a> hasn't been updated since 2013.</li>
  <li>The <a href="https://sourceforge.net/p/olap4j/mailman/olap4j-devel/" rel="nofollow noreferrer">last message</a> on the dev mailling list was in May 2016.</li>
  <li>The last available release build was <a href="https://mvnrepository.com/artifact/org.olap4j/olap4j" rel="nofollow noreferrer">1.2.0</a>, in 2016. There are more recent <a href="https://github.com/olap4j/olap4j/releases" rel="nofollow noreferrer">release tags</a>, but the build artefacts haven't been uploaded to any Maven repository.</li>
  </ul>
  
  <p>If it is dead, then is there a suitable replacement?</p>
