error in tutorial

[David Green]

This step fails:  

  

3\. Create a library  

Go to File -> Project Structure -> Libraries and add the JavaFX 13 SDK
as a library to the project. Point to the lib folder of the JavaFX SDK.  

  

The src.zip located in this package lib will cause the build in IJ to fail. I
don't know why, since it is source, albeit zipped.  

  

To get the project to build, I had to remove it. I placed it in a new src
folder I created at the same level as lib in the sdk.
