我看到这是一个 maven 项目。在 Maven 项目中，构建 jar 文件将位于 target 文件夹中。但是，如果您使用任何依赖项，它不会自动将它们附加到构建 jar 中。您需要将以下代码添加到 pom.xml 文件中。

<plugin>
  <artifactId>maven-assembly-plugin</artifactId>
  <configuration>
    <archive>
      <manifest>
        <mainClass>fully.qualified.MainClass</mainClass>
      </manifest>
    </archive>
    <descriptorRefs>
      <descriptorRef>jar-with-dependencies</descriptorRef>
    </descriptorRefs>
  </configuration>
  <executions>
    <execution>
      <id>make-assembly</id> <!-- this is used for inheritance merges -->
      <phase>package</phase> <!-- bind to the packaging phase -->
      <goals>
        <goal>single</goal>
      </goals>
    </execution>
  </executions>
</plugin>

通常此目标与自动执行的构建阶段相关联。因此，当您构建项目时，您的 fat.jar 文件将在您的目标文件夹中可用。

所以在你的情况下，你的 pom.xml 文件应该是这样的，

<?xml version="1.0" encoding="UTF-8"?>

    </properties>
