JAR无法识别引用的库

Question

When I launch jar file from terminal it gives java.lang.NoClassDefFoundError as obviously it cannot recognize referenced libraries that I have included in the project.

Exception in thread "JavaFX Application Thread" java.lang.NoClassDefFoundError: org/icepdf/core/exceptions/PDFException

However I have added them to build path.

I am using the following command to launch my application:

java -jar app.jar

What can be wrong?

If you have your core project in the workspace:

• Right click on the project that will use the core project in Eclipse
• Go to properties
• Then " Deployment Assembly " on the left
• Use the button Add on the right
• Choose project and search your core project and use the " Finish " button
• Built your project
