title: Ionic + Cordova Android build error - could not find tools.jar
body: <p>today I've upgrade my MacBook to macOS Big Sur version 11.0.1. Now there is a problem coming out when I tried to build the project for Android.</p>
  <pre><code>Execution failed for task ':CordovaLib:compileDebugJavaWithJavac'.
  &gt; Could not find tools.jar. Please check that /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home contains a valid JDK installation.
