使用 Maven 打成 jar 包，执行 main 方法

第一步：创建一个类，在类中声明一个main方法

package examples.task;

public class CollectTask {

	public static void main(String[] args) {
		System.out.println("测试执行jar包");
	}
	
}

 

第二步：在pom.xml文件中添加以下代码

<!-- java -jar main -->
<plugin>  
    <groupId>org.apache.maven.plugins</groupId>  
    <artifactId>maven-shade-plugin</artifactId>  
    <version>1.4</version>  
    <executions>  
        <execution>  
            <phase>package</phase>  
            <goals>  
                <goal>shade</goal>  
            </goals>
            <configuration>
            	<includeSystemScope>true</includeSystemScope>
                <transformers>  
                    <transformer  
                        implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">  
                        <resource>META-INF/spring.handlers</resource>  
                    </transformer> 
                    <transformer  
                        implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                        <!-- 要执行的class文件目录   -->
                        <mainClass>examples.task.CollectTask</mainClass>  
                    </transformer>  
                    <transformer  
                        implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">  
                        <resource>META-INF/spring.schemas</resource>  
                    </transformer>  
                </transformers>  
            </configuration>  
        </execution>  
    </executions>  
</plugin>
<!-- 加载jar包 -->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
        <execution>
            <id>copy</id>
            <phase>install</phase>
            <goals>
                <goal>copy-dependencies</goal>
            </goals>
            <configuration>
                <outputDirectory>${project.build.directory}/lib</outputDirectory>
            </configuration>
        </execution>
    </executions>
</plugin>

第三步：打开命令行窗口

或者指定 jdk 目录执行
