Cannot install a j-text-utils-0.3.3.jar - no main manifest attribute

Question

I'm trying to install j-text-utils to make a table. When I click on the jar file, nothing happens. So I tried make a .bat file and run the file from cmd. However, this shows up: no main manifest attribute, in j-text-utils-0.3.3.jar

I searched around and the problems were mainly with pom.xml and MANIFEST.MF. I dragged the file in Eclipse and the thing did have both pom.xml and MANIFEST.MF. Here is what the pom.xml looks like:

How may I fix this problem please? :(

I used the download link from Google Code: https://code.google.com/archive/p/j-text-utils/downloads

https://mvnrepository.com/artifact/com.massisframework/j-text-utils/0.3.4 Use this one instead — Toan Lu, Jun 21 '19 at 04:15

This .jar file is to be used as a library, not a as an executable application. To access the functionalities, you should write your own application in Java and import the needed classes contained in the j-text-utils-0.3.3.jar file. To be able to compile your Java code, the j-text-utils-0.3.3.jar needs to be available on the classpath. See this question for more info : What is a classpath and how do I set it?
