使用maven的具有依赖关系的可执行jar，无需解包jar，但包含类路径

Question

我在目标目录和lib目录中创建了executable.jar，所有依赖项jar都位于/lib Directoty下。

这是我的pom.xml的代码片段。我应该更改什么？

</dependencies> 
 <dependency>
<groupId><gId></groupId>
<artifactId><aId></artifactId>
<version><v></version>
</dependency>
<dependency>
<groupId>gI2</groupId>
<artifactId>aI2</artifactId>
<version>v</version>
</dependency>
</dependencies>
<build>
        <plugins>
            <plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <configuration>
                    <archive>
                        <manifest>
                            <mainClass>com.proj.app</mainClass>
                        </manifest>
                    </archive>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                </configuration>
            </plugin>
        </plugins>
    </build>

使用Maven阴影插件

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>1.6</version>
    <configuration>
        <createDependencyReducedPom>true</createDependencyReducedPom>
        <filters>
            <filter>
                <artifact>*:*</artifact>
                <excludes>
                    <exclude>META-INF/*.SF</exclude>
                    <exclude>META-INF/*.DSA</exclude>
                    <exclude>META-INF/*.RSA</exclude>
                </excludes>
            </filter>
        </filters>
    </configuration>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>shade</goal>
            </goals>
            <configuration>
                <transformers>
                    <transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer" />
                    <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                        <mainClass><Your main class here></mainClass>
                    </transformer>
                </transformers>
            </configuration>
        </execution>
    </executions>
</plugin>

这将在一个jar中包含所有依赖项，并自动将主类添加到清单文件中。

确保运行“包”目标。
