title: Dependency org.json:json:jar is missing
body: <p>I have a problem with the project I am working on. Until Tuesday everything seemed to be fine when I was building and running my project. Today I wanted to run the project and I received this error message: </p>
  
  <pre><code>  [ERROR] [ERROR] Some problems were encountered while processing the POMs:
      [ERROR] 'dependencies.dependency.version' for org.json:json:jar is missing. @ 
      line 57, column 21
  </code></pre>
  
  <p>After I added the version, the build is now failing due to this exception: </p>
