Errors when I try to build my Java project in VS Code

I'm working with Java in VS Code. I imported time4j lib into my project and when I try to compile the project the errors occur:

Executing task: gradlew build   -Dorg.gradle.java.home="C:\Users\Public\wpilib\2020\jdk" <

Compilation Error!
GradleRIO detected this build failed due to a Compile Error (compileJava).
Check that all your files are saved, then scroll up in this log for more information.

FAILURE: Build failed with an exception.

But when I was writing the program there was no any errors and time4j was ok! I'm new in java and I don't understand what I'm doing wrong. Thanks!

First, check the referenced path of time4j and make it right because the error was package net.time4j does not exist;

If it does exist, we can try:

  1. Download the .jar file and copy it to the /libs/ folder in the application project;

  2. Open at the root level of the project build.gradle File and edit the dependency to include the new .Jar file: dependency {compile filetree (DIR: 'libs', include:' *. Jar ')};

  3. Rebuild the project.
