我仔细阅读了这些响应中的每一个，希望创建一个包含所有依赖项的可执行JAR文件，但没有一个能正常工作。答案是shade插件，它非常简单明了。

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-shade-plugin</artifactId>
  <version>2.3</version>

  <executions>
    <!-- Run shade goal on package phase -->
    <execution>
      <phase>package</phase>
      <goals>
        <goal>shade</goal>
      </goals>

      <configuration>
        <transformers>
          <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
            <mainClass>path.to.MainClass</mainClass>
          </transformer>
        </transformers>
      </configuration>
    </execution>
  </executions>

</plugin>

请注意，您的依赖项需要有编译或运行时的范围才能正常工作。

这个例子来自mkyong.com

添加到文件pom.xml：

<dependency>
    <groupId>com.jolira</groupId>
    <artifactId>onejar-maven-plugin</artifactId>
    <version>1.4.4</version>
</dependency>

And

<plugin>
    <groupId>com.jolira</groupId>
    <artifactId>onejar-maven-plugin</artifactId>
    <version>1.4.4</version>
    <executions>
        <execution>
            <goals>
                <goal>one-jar</goal>
            </goals>
        </execution>
    </executions>
</plugin>

接下来，mvn包还将另外创建一个胖JAR，包括所有依赖JAR文件。

您可以将以下内容添加到pom.xml文件中：

<build>
<defaultGoal>install</defaultGoal>
<plugins>
  <plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.3.2</version>
    <configuration>
      <source>1.6</source>
      <target>1.6</target>
    </configuration>
  </plugin>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.3.1</version>
    <configuration>
      <archive>
        <manifest>
          <addClasspath>true</addClasspath>
          <mainClass>com.mycompany.package.MainClass</mainClass>
        </manifest>
      </archive>
    </configuration>
  </plugin>
  <plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
      <descriptorRefs>
        <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
      <archive>
        <manifest>
          <mainClass>com.mycompany.package.MainClass</mainClass>
        </manifest>
      </archive>
    </configuration>
    <executions>
      <execution>
        <id>make-my-jar-with-dependencies</id>
        <phase>package</phase>
        <goals>
          <goal>single</goal>
        </goals>
      </execution>
    </executions>
  </plugin>
</plugins>
</build>

然后，您必须通过控制台切换到pom.xml文件所在的目录。然后，您必须执行mvn assembly：single，然后希望构建具有依赖关系的可执行JAR文件。您可以在切换到带有cd的输出（目标）目录时检查它/目标并使用类似于java-jarmavenproject1-1.0-SNAPSHOT-JAR-with-dependencies.JAR的命令启动JAR。

我用Apache Maven 3.0.3测试了这一点。

为了解决这个问题，我们将使用Maven Assembly插件，该插件将JAR文件及其依赖JAR文件一起创建为单个可执行JAR文件。只需在pom.xml文件中添加以下插件配置。

<build>
   <pluginManagement>
      <plugins>
         <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-assembly-plugin</artifactId>
            <configuration>
               <archive>
                  <manifest>
                     <addClasspath>true</addClasspath>
                     <mainClass>com.your.package.MainClass</mainClass>
                  </manifest>
               </archive>
               <descriptorRefs>
                  <descriptorRef>jar-with-dependencies</descriptorRef>
               </descriptorRefs>
            </configuration>
            <executions>
               <execution>
                  <id>make-my-jar-with-dependencies</id>
                  <phase>package</phase>
                  <goals>
                     <goal>single</goal>
                  </goals>
               </execution>
            </executions>
         </plugin>
      </plugins>
   </pluginManagement>
</build>

完成此操作后，不要忘记使用以下命令运行Maven工具：

mvn clean compile assembly:single

Maven-将JAR文件及其依赖JAR文件一起创建为单个可执行JAR文件

        <plugin>

                    <!-- bind to the packaging phase -->
                    <phase>package</phase>
                    <goals>
                        <goal>single</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
