Issue
I created a JavaFX Ant project in Apache Netbeans 12.0 with the JDK 11 from bellsoft. Then i created a database connection with an sqlite database, which is a file on my pc. In this database are two tables.
I clicked right on the project and selected "New->Entity Classes from Database...", then i created the two classes from the tables. Now i want to clean and build the project, but i get this error.
Does anybody know how to solve this problem? Is it because of the jdk?
