<build>
  <plugins>
    <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>
        <archive>
          <manifest>
            <mainClass>fully.qualified.MainClass</mainClass>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
    </plugin>
  </plugins>
</build>

然后你运行它

mvn clean compile assembly:single

编译目标应该在assembly之前添加:single，否则您自己的项目上的代码将不包括在内。

请在评论中查看更多详细信息。

通常，此目标被绑定到构建阶段以自动执行。这确保了在执行mvn install或执行部署/发布时构建JAR。

<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>

在包阶段之前，您可以使用依赖项插件在单独的目录中生成所有依赖项，然后将其包含在清单的类路径中：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
        <execution>
            <id>copy-dependencies</id>
            <phase>prepare-package</phase>
            <goals>
                <goal>copy-dependencies</goal>
            </goals>
            <configuration>
                <outputDirectory>${project.build.directory}/lib</outputDirectory>
                <overWriteReleases>false</overWriteReleases>
                <overWriteSnapshots>false</overWriteSnapshots>
                <overWriteIfNewer>true</overWriteIfNewer>
            </configuration>
        </execution>
    </executions>
</plugin>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
        <archive>
            <manifest>
                <addClasspath>true</addClasspath>
                <classpathPrefix>lib/</classpathPrefix>
                <mainClass>theMainClass</mainClass>
            </manifest>
        </archive>
    </configuration>
</plugin>

或者，使用${project.build.directory}/classes/lib作为OutputDirectory将所有jar文件集成到主jar中，但随后您将需要添加自定义类加载代码来加载jar。

请参阅executable-jar-with-maven-example (GitHub)

备注

这些利弊都是由Stephan提供的。

用于手动部署

最终jar.之外的

Pros
Cons
- 依赖项

将依赖项复制到特定目录

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-dependency-plugin</artifactId>
  <executions>
    <execution>
      <id>copy-dependencies</id>
      <phase>prepare-package</phase>
      <goals>
        <goal>copy-dependencies</goal>
      </goals>
      <configuration>
        <outputDirectory>${project.build.directory}/${project.build.finalName}.lib</outputDirectory>
      </configuration>
    </execution>
  </executions>
</plugin>

使Jar可执行文件和类路径可识别

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-jar-plugin</artifactId>
  <configuration>
    <archive>
      <manifest>
        <addClasspath>true</addClasspath>
        <classpathPrefix>${project.build.finalName}.lib/</classpathPrefix>
        <mainClass>${fully.qualified.main.class}</mainClass>
      </manifest>
    </archive>
  </configuration>
</plugin>

此时，jar实际上是可使用外部类路径元素执行的。

$ java -jar target/${project.build.finalName}.jar

创建可部署的归档文件

只有同级...lib/目录才能执行jar文件。我们需要使存档与目录及其内容一起部署。

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-antrun-plugin</artifactId>
  <executions>
    <execution>
      <id>antrun-archive</id>
      <phase>package</phase>
      <goals>
        <goal>run</goal>
      </goals>
      <configuration>
        <target>
          <property name="final.name" value="${project.build.directory}/${project.build.finalName}"/>
          <property name="archive.includes" value="${project.build.finalName}.${project.packaging} ${project.build.finalName}.lib/*"/>
          <property name="tar.destfile" value="${final.name}.tar"/>
          <zip basedir="${project.build.directory}" destfile="${final.name}.zip" includes="${archive.includes}" />
          <tar basedir="${project.build.directory}" destfile="${tar.destfile}" includes="${archive.includes}" />
          <gzip src="${tar.destfile}" destfile="${tar.destfile}.gz" />
          <bzip2 src="${tar.destfile}" destfile="${tar.destfile}.bz2" />
        </target>
      </configuration>
    </execution>
  </executions>
</plugin>

现在您有了分别包含jar和lib/*的target/${project.build.finalName}.(zip|tar|tar.bz2|tar.gz)。

Apache Maven程序集插件

Pros
Cons阴影插件不支持类重定位(如果类重定位为needed).

，请使用maven--

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-assembly-plugin</artifactId>
  <executions>
    <execution>
      <phase>package</phase>
      <goals>
        <goal>single</goal>
      </goals>
      <configuration>
        <archive>
          <manifest>
            <mainClass>${fully.qualified.main.class}</mainClass>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
    </execution>
  </executions>
</plugin>

你有target/${project.bulid.finalName}-jar-with-dependencies.jar。

Apache Maven Shade插件

Pros
Cons

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-shade-plugin</artifactId>
  <executions>
    <execution>
      <goals>
        <goal>shade</goal>
      </goals>
      <configuration>
        <shadedArtifactAttached>true</shadedArtifactAttached>
        <transformers>
          <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
            <mainClass>${fully.qualified.main.class}</mainClass>
          </transformer>
        </transformers>
      </configuration>
    </execution>
  </executions>
</plugin>

你有target/${project.build.finalName}-shaded.jar。

onejar-maven-plugin

Pros
Cons

        <goal>one-jar</goal>
      </goals>
    </execution>
  </executions>
</plugin>

Spring Boot Maven插件

Pros
Cons
- 添加与弹簧和弹簧启动相关的潜在不必要的classes.

<plugin>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-maven-plugin</artifactId>
  <executions>
    <execution>
      <goals>
        <goal>repackage</goal>
      </goals>
      <configuration>
        <classifier>spring-boot</classifier>
        <mainClass>${fully.qualified.main.class}</mainClass>
      </configuration>
    </execution>
  </executions>
</plugin>

你有target/${project.bulid.finalName}-spring-boot.jar。
