Preface

Before we talk about these two ways, let's explain what the jar file in java is.

Jar (Java Archive File), translated is the java archive file, in fact, it is also similar to our windows zip file, the only difference is that in the content of the JAR file, contains a META-INF/MANIFEST.MF file, this file is automatically created when the JAR file is generated, contains the description of the JAR package, the full class name of the main class and other information.

1.File-- > Project Structure-- > Artifacts-- > Jar-- > From module with dependencies.

After clicking ok, we found in the previous step Project Structuer that our jar package output directory has been filled in by default in IDEA. At this time, we can change the above jar package output directory, which is more convenient to manage. At this time, we can change the number path and click Apply in the lower right corner.
