SpringBoot无主清单属性（maven）

Question

当运行我的jar文件：java-jar target/places-1.0-snapshot.jar时，我得到了下一个错误：

no main manifest attribute, in target/places-1.0-SNAPSHOT.jar

我的pom.xml包含spring-boot-maven-plugin：

 <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <mainClass>com.places.Main</mainClass>
            </configuration>
 </plugin>

<properties>
      <!-- The main class to start by executing "java -jar" -->
      <start-class>com.places.Main</start-class>
</properties>

@SpringBootApplication
 public class Main {
public static void main(String[] args) throws InterruptedException {
    SpringApplication.run(Main.class,args);
  }
  }

知道我还能试试什么吗？

尝试将重新打包目标添加到执行目标中。否则，您需要将插件显式地调用为mvn package spring-boot:repackage。添加了目标后，您只能调用mvn package。

<plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <configuration>
            <mainClass>com.places.Main</mainClass>
        </configuration>

        <executions>
            <execution>
                <goals>
                    <goal>repackage</goal>
                </goals>
            </execution>
       </executions>

</plugin>
