title: How to override quartz's property value
body: <p>I have spring boot application with it's application.properties file. The project has a dependency on third-party library, in my case its:</p>
  
  <pre><code>&lt;dependency&gt;
      &lt;groupId&gt;org.quartz-scheduler&lt;/groupId&gt;
      &lt;artifactId&gt;quartz&lt;/artifactId&gt;
      &lt;version&gt;2.3.0&lt;/version&gt;
  &lt;/dependency&gt;
  </code></pre>
  
  <p>The library has its <strong>quartz.properties</strong> file with configs. I would like to override some values, e.g.:</p>
  
  <pre><code>org.quartz.threadPool.threadCount:10
  </code></pre>
  
  <p>to have another number of threads.</p>
  
  <p>How can I do it using my own properties file and/or environment variable?</p>
