Issue
Description :
Type The project was not built since its build path is incomplete.
Cannot find the class file for weka.core.Instance.
Fix the build path then try building this project.
It is not an android code, also do I need to post some code too. I think code is irrelevant for this error
Tried this solution: Right click on project -> Properties -> Java Build Path (From Left List) -> Libraries (Tab) -> Add Library (Button on right) -> JRE System Library -> Next -> Workspace default JRE -> Finish
given in similar question on stackoverflow for Android Project - Didn't work.
Solution
It says it all: there's a missing library in your class path. Try downloading the jar from here and add it to your class path. If you're using maven, gradle, etc., even simpler, just use the code provided in the previous link for each tool.
