I am working on a web visualisation for a given project (db with genes, proteins, task is to do some nice visualisation with springboot and thymeleaf). The project was provided with all files, yet I am missing some libraries (also leading to some errors in the code ofc).
When trying to import:
import org.apache.commons.lang3.tuple.ImmutablePair;
import org.apache.commons.lang3.tuple.Pair;
lang3 gives me a "cannot resolve symbol" error and automatically searching jars on web results in "no jars found".I found the lang3-jar manually and successfully added it to the project library. When importing:
import org.apache.commons.lang3.*;
All errors for tuple.Pair-usage are gone. Yet, usage of ImmutablePair still results in a "cannot resolve symbol" error.
Firstly, I am confused and now unsure, if my knowledge of imports is correct. I learned, if for example you import something.anything.x and something.anything.y, you could also just import something.anything.*; and x and y would be covered.
Secondly, if needed, where do I find the jars I need (I could not find them yet).
Thanks :)
So, I do not know, where this error results in, yet I do know a solution. When adding the library, select "From Maven" and search for Apache lang3 and add it. Resolves the problems.
