My program may use a library when it is present at runtime, but it is not required to have this library to run the program. However, when I run my program (without the library being present), it complains that it is not present for a very specific import:
java.lang.NoClassDefFoundError: nl/lolmewn/stats/api/storage/StorageException

The code that uses this StorageException class is this:
try {
user = stats.getUserManager().loadUser(player.getUniqueId(), stats.getStatManager());
} catch (StorageException e) {
e.printStackTrace();
}
Note that I have many imports using this library. The odd thing is that when I leave out the StorageException import (e.g. change it to a general Exception), it does not give any error anymore, even though there are other imports (from the exact same library) present!
Obviously, I want to use the StorageException class for catching errors, but I can't seem to do this.
How can I solve this issue?
