SpringBoot no main manifest attribute (maven)

Question

When running my jar file: java -jar target/places-1.0-SNAPSHOT.jar

I'm getting the next error :

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

The pom.xml contains the spring-boot-maven-plugin:

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

I also tried to create a MANIFEST.MF file and specifying the class, but it didnt help.

In addition, I also tried:

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

Main class:

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

Any idea what else can I try?

Try adding repackage goal to execution goals.

Otherwise you would need to call the plugin explicitly as mvn package spring-boot:repackage.

With the goal added, you have to call only 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>
