Non-resolvable parent POM in Eclipse

Question

I've imported a maven project in to Eclipse Version: 2018-09 (4.9.0), but I have this error in the pom file. I have already the same project in another computer and it is working fine. The project is a springBoot 2.0.6.RELEASE

Project build error: Non-resolvable parent POM for es.teatreDeGuerrila:teatreDeGuerrilaCloudApp:1.0.0-SNAPSHOT: Failure to transfer org.springframework.boot:spring-boot-starter-parent:pom:2.0.6.RELEASE from 
 https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: 
 Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.0.6.RELEASE from/to central (https://repo.maven.apache.org/maven2): connect timed out and 
 'parent.relativePath' points at no local POM

and I have a lot of compilation errors in the classes, like

The import org.springframework cannot be resolved

from the command line, using mvn install -Dmaven.test.skip=true, everything works fine.

and I already the proxy in Eclipse as Manual with the same settings I have in the file ../maven/conf/settings.xml

<proxy>
      <id>httpproxy</id>
      <active>true</active>
      <protocol>http</protocol>
      <host>proxy.teatre.guerrila.int</host>
      <port>8080</port>
      <nonProxyHosts>localhost|127.0.0.1</nonProxyHosts>
    </proxy>
     <proxy>
      <id>httpsproxy</id>
      <active>true</active>
      <protocol>https</protocol>
      <host>proxy.teatre.guerrila.int</host>
      <port>8443</port>
      <nonProxyHosts>localhost|127.0.0.1</nonProxyHosts>
    </proxy>
  </proxies>

It seems that you are using an external maven and not the embedded one. Please check that

1) In eclispe -> preferences -> Maven -> Installations you have checked the external maven

2) In eclispe -> preferences -> Maven -> User Settings pont to the settings file you mention
