Not able to submit breakpoint LineBreakpoint wicket on netbeans

Question

I'm using Netbeans on Ubuntu. I opened a Wicket application. My project had three packages. But I deleted one. It has EventCollection. Now My Project has two packages. Now I want to run it but it is not run. It gives error.

I did debug. It gives this error:

Attaching to localhost:11555
Not able to submit breakpoint LineBreakpoint EventCollection.java : 95, reason: The breakpoint is set outside of any class.
Invalid LineBreakpoint EventCollection.java : 95
User program running

Than name of existed package change with Events and name of CategoryCollection.java change with EventCollection.java

Solution 1

Remove that breakpoint from the IDE. I don't use NetBeans but this question seems to suggest that you can find this option under the Window / Debugging / Breakpoints menu. remove breakepoint in netbeans 6.8.

Solution 2

Just to delete all contente from folder: C:\Users\YOUR_USER\AppData\Roaming\NetBeans\12.1
