Command line approach:
命令行方法：
In the root of the project (the maven project), should be a pom.xml. Go to that root and run mvn package. If this is correct, there should be a new folder with the name targetin the root of the project. Inside this folder there should be the jar file.
在项目的根目录（maven 项目），应该是一个 pom.xml。转到该根目录并运行mvn package。如果这是正确的，项目根目录中应该有一个名为target的新文件夹。在这个文件夹中应该有 jar 文件。

First of all, you have to remember about security in Java. Many jars would not work in fatjars, if they got included in other projects (for example bouncycastle).
首先，您必须记住 Java 中的安全性。如果它们被包含在其他项目中（例如 bouncycastle），许多 jars 将无法在 fatjars 中工作。
If you are doing a simple executable jar that has no libs in it, and requires all of them on classpath, default build (when packageing tag is set to jar) would be ok, and just require a proper manifest.
如果您正在做一个没有库的简单可执行 jar，并且需要在类路径上的所有库，默认构建（当打包标记设置为 jar 时）就可以了，只需要一个正确的清单。
If you need all libs inside (fatjar), you need to configure it yourself.
如果需要里面的所有库（fatjar），需要自己配置。
There are several plugins for it, for example maven-shade-plugin:
它有几个插件，例如maven-shade-plugin：
