Insoluble POM import Impossibility to find

Question

I experimented with the spring loading module in the parent pom and now I get the error

[ERROR] [ERROR] Some problems were encountered while processing the POMs:

I tried removing myproject in .m2local repo

I have a maven project with two modules (plain java and spring loading). I retrieve the parent from spring to load into the main pom, for example dependensyManagment, and set the paren parameter for spring boot-main project. After that I get this error

I am returning the changes and everything is working fine. Step by step, I stop when everything is crushed

• I add this to the main pom

<dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-dependencies</artifactId>
        <version>2.0.0.M6</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>
    </dependencies>   </dependencyManagement>

2. in spring boot I change this

<parent>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-parent</artifactId>
      <version>2.0.0.M6</version>
      <relativePath/> <!-- lookup parent from repository -->
  </parent>

:

<parent>
        <artifactId>main-project</artifactId>
        <groupId>main.project</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>

2.0.0.M6 http://repo.maven.apache.org/maven2. , maven repo http://repo.spring.io/milestone. POM:

<repositories>
    <repository>
        <id>spring-milestone-repo</id>
        <url>http://repo.spring.io/milestone/</url>
    </repository>
</repositories>

spring -boot (1.5.8.RELEASE), . , POM, spring POM -:

1. spring POM

2. spring -Boot in Dependency-Management

POM, spring POM:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-dependencies</artifactId>
