【SpringBoot】（解决）springboot的package打包jar失败, 如何运行jar包

springboot在idea里面package打包成jar失败?

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:3.2.0:resources (default-resources) on project gogo: Input length = 1 -> [Help 1]

解决方法:

添加Maven的打包插件;

<build>
	<plugins>
		<plugin>
			<groupId>org.apache.maven.plugins</groupId>
			<artifactId>maven-resources-plugin</artifactId>
			<version>3.1.0</version>
		</plugin>
		<plugin>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-maven-plugin</artifactId>
		</plugin>
	</plugins>
</build>

然后先clean再package打包即可;

结果:

运行jar包:

在jar包的文件夹里,按住shift键,然后鼠标右击,“在此处打开Powershell窗口”;

在Powershell窗口输入:

java -jar xxx.jar

jar包名字太长的话,可以输入前几个字母,然后按tab键补齐;
