多模塊彈簧引導配置

我試圖配置一個多模塊彈簧引導應用程序。最簡單的例子是：多模塊彈簧引導配置

RootConfig：

package testExamplePackage; 

import org.springframework.boot.autoconfigure.SpringBootApplication; 

@SpringBootApplication 
public class RootConfig { 

    public static void main(String[] args) { 
     System.out.println("Doing some work..."); 
    } 
}

爲什麼我得到一個錯誤開始MAV en'clean spring-boot：run'？

它想要mainClass，但是這個類已經被指定了。

mvn clean spring-boot:run必須從包含SpringBootApplication的模塊執行。
您可以從父pom中執行它。

執行此命令從module1，它應該工作。

<build> 
    <plugins> 
     <plugin> 
      <artifactId>maven-compiler-plugin</artifactId> 
      <version>3.1</version> 
      <configuration> 
       <source>1.8</source> 
       <target>1.8</target> 
      </configuration> 
     </plugin> 
    </plugins> 
</build>

：

順便提一下，因爲它已經被你的父母規定不需要在module1的pom.xml這個重複申報
