Answer

Check whether the compiled log4j.properties file exists in the bin directory of the project. If it does not, add the compilation path.

  1. In IntelliJ IDEA, choose File > Project Structure > Modules, and then add the conf folder that contains log4j.properties and UserInfo.properties as Source Folders.
  2. Compile the file again.
