title: Can you install sbt 0.12.4, scala 2.10.6 and java 7 on MacOS Catalina?
body: <p>We have a <strong>legacy</strong> Scala project that we need to make changes to and compile on MacOS Catalina. Its summarized config is:</p>
  <pre><code>scalaVersion := &quot;2.10.6&quot;
  sbt.version=0.12.4
  Java 7
  </code></pre>
  <p>At this stage we don't have the resources to upgrade the project to more current versions.</p>
  <p>I installed Java 7.</p>
  <pre><code>java version &quot;1.7.0_80&quot;
  Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
  Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)
  </code></pre>
  <p>I've been trying to install <strong>sbt 0.12.4</strong> on MacOS Catalina without success and after several days have exhausted my options.</p>
  <ol>
  <li><p>I've tried installing as per the <a href="https://www.scala-sbt.org/0.12.4/docs/Getting-Started/Setup.html#id1" rel="nofollow noreferrer">official manual installation instructions</a> using <code>sbt-launch.jar</code> but during installation many of the dependencies are no longer available.</p>
  </li>
  <li><p>I've tried using the <a href="https://github.com/paulp/sbt-extras" rel="nofollow noreferrer">sbt-extras</a> script but when running it I get:</p>

  </code></pre>
  <p>We have previously compiled our own cache of dependencies (some of which have become outdated) by manually finding the dependencies which we then place in our <code>~/.ivy2/cache</code> before compiling. In this case I cannot find <code>jna3.2.3</code> to include it in <code>/Users/theuser/.ivy2/local/net.java.dev.jna/jna/3.2.3/</code> as a work-around to see if I can get any further.</p>
  <ol start="3">
  <li>I have copied the <code>sbt 0.12.4</code> config, folders and ivy cache from another Mac where sbt and the legacy project currently works. Doesn't work.</li>
  </ol>
  <p>Any help or clues would be appreciated.</p>
