无法执行目标 org.springframework.boot:spring-boot-maven-plugin:2.5.5:run (default-cli)

Question

我是 Spring 的新手，我试图按照其官方网站上给出的教程进行操作，但会弹出此错误。

Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.5.5:run (default-cli) on project backend: Application finished with exit code: 1 -> [Help 1]

以下是我的pom.xml

知道为什么不起作用吗？ 我已经根据其他人的错误尝试了很多方法，但都没有奏效。 现在有点沮丧。 任何援助将不胜感激

Answer 1

这个错误基本上是由于插件问题。

通过运行这些命令为项目创建一个 jar

mvn clean install然后java -jar jar-localtion.jar
