Start a spring boot project witout the parent part-CodePudding

I am currently working on migrating an appache CXF project to Spring BOOT.

My problem is that this project depend on two other projects and in order to import them into maven I need to declare the parent project like this:

<parent>
   <groupId>com.comapny.dd</groupId>
   <artifactId>ProjectMainJars_Parent</artifactId>
   <version>${version}</version>
 </parent>

but in order to use Spring Boot. I need to declare the parent like this:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.4.0</version>
</parent>

I added the following code:

 <dependencyManagement>
    <dependencies>

      <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-dependencies</artifactId>
        <version>2.4.0</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>

    </dependencies>
  </dependencyManagement>

I still get the following error:

Exception in thread "main" java.lang.AbstractMethodError: org.springframework.boot.env.EnvironmentPostProcessorApplicationListener.supportsSourceType(Ljava/lang/Class;)Z
    at org.springframework.context.event.GenericApplicationListenerAdapter.supportsSourceType(GenericApplicationListenerAdapter.java:81)
    at org.springframework.context.event.AbstractApplicationEventMulticaster.supportsEvent(AbstractApplicationEventMulticaster.java:294)
    at org.springframework.context.event.AbstractApplicationEventMulticaster.retrieveApplicationListeners(AbstractApplicationEventMulticaster.java:224)
    at org.springframework.context.event.AbstractApplicationEventMulticaster.getApplicationListeners(AbstractApplicationEventMulticaster.java:195)
    at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:133)

Is it possible to use spring boot without needing to change parent.
PS: I only need to create a REST service.

Thank you in advance.

If you have to specify some other artifact as parent, then spring boot needs to be moved under dependencyManagement tag parallel to dependencies like this:

  <dependencyManagement>
    <dependencies>

      <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-dependencies</artifactId>
        <version>2.4.0</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>

    </dependencies>
  </dependencyManagement>

  <dependencies>
  </dependencies>

I know it might be late but I figured out how to do it:
First make sure to clean the parent directory from any Spring dependency and then in the child project specify the following:

 <dependencyManagement>
    <dependencies>

      <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-dependencies</artifactId>
        <version>2.4.0</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>

    </dependencies>
  </dependencyManagement>

  <dependencies>
  </dependencies>
