无法在 Java 中导入 log4j 类

Question

I am getting started with log4j and i am stuck at the very first point which is to import the classes successfully and to make it run.

I have already added the external jars for log4j 1.2 api -2.14.1 But i am unable to import the classes.

This is my code with all the jars i have imported

This is the exception i am getting after running the code

Edit: So i did a bit of digging myself and sorted the above error by the below steps:

1. Go to your project properties by right clicking on it.
2. Go to "Java Build Path".
3. Go to Libraries and Select JRE
4. Edit and Set Exxeecution Environment to JRE 1.1

Answer 1

I see you have log4j-api but you also need log4j-core installed as well.
