Java lib with plugin dependency

I have a java project where I have some APIs that rely on some eclipse plugins. I run the code as a java application from my eclipse and they work fine. Then I tried to export them as a standard Java lib (*.jar) . for some reason they don’t work on another eclipse (with different plugin directory ) even though I copy pasted those plugins from the original plugin directory to the new one ? Can anyone help me to resolve this problem ?

Thanks
