When I run "Clear and Build Project" I got the following errors:
Not copying library C:\Users\00035583\Documents\NetBeansProjects\commons-beanutils-1.9.3.jar , it can't be read.
Not copying library C:\Users\00035583\Documents\NetBeansProjects\commons-collections4-4.1.jar , it can't be read. Not copying library C:\Users\00035583\Documents\NetBeansProjects\commons-collections-3.2.1-1.0.0.jar , it can't be read. Not copying library C:\Users\00035583\Documents\NetBeansProjects\dom4j-1.6.1-sources.jar , it can't be read. Not copying library C:\Users\00035583\Documents\NetBeansProjects\Kontrol Paneli\dist\lib\commons-beanutils-1.9.3.jar , it can't be read.
I can understand that it requires the above jars, but I don't need them, so I removed them. Can you help me understand why these errors occur?
