title: Dockerfile maven value
body: <p>Which would be the correct value for this if I have an springboot app running on jdk 15? or where can I find the correct value for it?</p>
  <pre><code>FROM maven:3.6.3-jdk-11 AS builder
  </code></pre>
  <p>I tried 3.6.3-jdk-15 but of course that was a guess and it did not work, is there a source from where I can get this?. (trying to use maven for building the image)</p>
