Netbeans stuck at startup

Question

I was working with a big project on Netbeans. I attached some source code on third party library and all went smooth. Today I have the following popup message (I already had seen before obviously):

The file [...] cannot be safely opened with encoding windows-1252. Do you want to continue opening it?

The two buttons, yes and no, are not responsive. If I close the popup with the red cross it does nothing after a 1 sec loading. Is there a way to "clean" the open file in the netbeans workspace to avoid this error?

SO Windows 8.1, Netbeans 8.0.2

Thanks.

Answer 1

One general solution to this kind of problem can be to clear the netbeans cache.

Quit NetBeans and find the cache folder - mine is at C:\Users\OldCurmudgeon\AppData\Local\NetBeans\Cache. Delete the whole folder - this can take a while as there can be a lot of files in there.

Netbeans will create a new one on next start.

Note that this will slow down netbeans for a while but it won't be long before it is back up to speed again.

Answer 2

1. Quit NetBeans.
2. go to the last Project folder then remove the project from the folder.
3. Open NetBeans.
