  <p>in C module's build.gradle it has dependency:</p>
  
  <pre><code>implementation("com.dev.base:lib_X:$versions.xxx)
  </code></pre>
  
  <p>I have the lib_X source on the machine and would like to include the lib_X's source code in this project,  so in the module C's settings.grdale added:</p>
  
  <pre><code>include ':lib_X'
  project(':lib_X').projectDir = new File(settingsDir, '../../lib_X_proj/lib_X/')
  </code></pre>
  
  <p>and in the C module's build.gradle change the dependency:</p>
  
  <pre><code>implementation(":lib_X")
  </code></pre>
  
  <p>but got error says <code>:lib_X cannot be found</code>.  What would be wround?  The lib_X's relative code path is correct.</p>
