External Jar is not visible from classes under a package

Question

I have an external.jar in my maven project running with IntelliJ. My class1 cannot resolve my external.jar until I remove it out from package1. Could you please suggest me a best practice in order to solve such a problem by keeping the folder structure as below.

mvn -v : Apache Maven 3.6.0, Java version: 1.8.0_212

Folder Structure:
-src
--test

---java
----package1
-----class1
----package2

---resources
----external.jar

-target
-External Libraries

You keep all your external jars under lib folder. Refer below link

This link describes `lib` folder _under Java home directory_, not in your project. – Alexey Romanov Jul 01 '19 at 11:44
Yes, you are right. Please use "lib/rt.jar" in place of "${java.home}/lib/rt.jar. " so It takes from your project folder where your pom.xml exists. – Shivaraja HN Jul 01 '19 at 11:50

JAR is already included with this way and for that reason, there is no issue when sourcing class is not placed under a package. My problem occurs when I put my class into a package and try to use my jar. – serkmen Jul 01 '19 at 12:24
What error you are getting? When you move the class to that package did you refactor copied? – Hasitha Jayawardana Jul 02 '19 at 03:24
