Hi there. I have this error since I want to use SQLite (because I want to make a plugin compatible with mysql and sqlite, both of them). It doesn't detects the class "org.sqlite.JDBC", and I tried many ways: Importing as external jar at buildpath, importing as internal jar at buildpath, editing "classpath" file, etc... Nothing works. I'm actually using Eclipse Neon.3. P.S.: It happened again some months ago with Hikari libs. What can I do? Thank you.
