Eclipse export .jar with referenced libraries

Question

I've added a few libraries to my project as external jars, one being HikariCP ( https://github.com/brettwooldridge/HikariCP ) however when I run my jar I'm given these errors

java.lang.NoClassDefFoundError: com/zaxxer/hikari/HikariDataSource

and

Caused by: java.lang.ClassNotFoundException: com.zaxxer.hikari.HikariDataSource

I've tried to bundle these libraries by exporting the project as a "Runnable Jar file" and ticked "Package required libraries into generated jar", however the same errors still persist.

I don't currently have my project set up with Maven, as I've never had the reason to use it (until now?) I've heard this is easy to accomplish via Maven however I was wondering if there's another workaround without it.

Answer 1

Try running after including .classpath file in the jar file. You can include the .classpath file from the jardesc in eclipse.

Answer 2

Unpack libs. Next Alt-Enter => Java Build Path => Libraries => 1. Remove packed library 2. Click "Add External Class Folder" 3. Select your folder with library(-es) 4. Click OK 5. Enjoy :)
