What is difference between the User Libraries and external libraries

[shukla raghav]

It is very confusing that we add jar to a project in number of way in eclipse but why so many different ways for adding jars.

1. Windows >> Preference >> Java >> BuildPath >> UserLibraries

2. Right Click the project >> Properties>>java Build Path >> Libraries >> Select Add external Libraries

3. Right Click the project >> Build Path >> Libraries >> Select Add external Libraries

what is the difference between adding User Libraries and external libraries i.e. what is difference between 1 and 2.

User libraries are jars which Eclipse is already aware of. e.g. WEB-INF/lib
External libraries are jars which are outside your project scope.
