title: gradlew command not found?
body: <p>I am working on a Java project with gradlew. I use Ubuntu Linux as my OS. When I run &quot;gradle&quot; it runs, and gives me info. But when I run &quot;gradlew&quot;, it outputs as &quot;No command 'gradlew' found, did you mean:
  Command 'gradle' from package 'gradle' (universe)
  gradlew: command not found&quot;</p>
  <p>I did my research, I have jdk, and I did sudo apt-get install gradle. I am totally clueless</p>
  <p>Error is:</p>
  <pre><code>$ gradlew clean jpackage
  bash: gradlew: command not found...
  </code></pre>
