Description

Relocating parent POM do not work.

Reproduce steps:

1. Create following POM files :
   parent-pom-a.pom

   <?xml version="1.0" encoding="UTF-8"?>
   <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
       <modelVersion>4.0.0</modelVersion>
   
       <groupId>com.acme</groupId>
       <artifactId>parent-pom-a</artifactId>
       <version>1.0.0</version>
       <packaging>pom</packaging>
   
       <distributionManagement>
           <relocation>
               <groupId>com.acme</groupId>
               <artifactId>parent-pom-b</artifactId>
               <version>1.0.0</version>
           </relocation>
       </distributionManagement>
   </project>
   

   parent-pom-b.pom

   <?xml version="1.0" encoding="UTF-8"?>
   <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
       <modelVersion>4.0.0</modelVersion>
   
       <groupId>com.acme</groupId>
       <artifactId>parent-pom-b</artifactId>
       <version>1.0.0</version>
       <packaging>pom</packaging>
   
       <properties>
           <properties-from-parent-pom>b</properties-from-parent-pom>
       </properties>
   </project>
   

   project-pom.pom

   <?xml version="1.0" encoding="UTF-8"?>
   <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
   	<modelVersion>4.0.0</modelVersion>
   
   	<parent>
   		<groupId>com.acme</groupId>
   		<artifactId>parent-pom-a</artifactId>
   		<version>1.0.0</version>
   	</parent>
   
   	<artifactId>project-pom</artifactId>
   	<packaging>pom</packaging>
   
   	<properties>
   		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
   		<maven.compiler.encoding>${project.build.sourceEncoding}</maven.compiler.encoding>
   		<project.reporting.outputEncoding>${project.build.sourceEncoding}</project.reporting.outputEncoding>
   	</properties>
   
   	<build>
   		<plugins>
   			<plugin>
   				<groupId>com.github.ekryd.echo-maven-plugin</groupId>
   				<artifactId>echo-maven-plugin</artifactId>
   				<version>2.0.0</version>
   				<executions>
   					<execution>
   						<goals>
   							<goal>echo</goal>
   						</goals>
   						<phase>initialize</phase>
   						<configuration>
   							<message>properties-from-parent-pom: ${properties-from-parent-pom}</message>
   						</configuration>
   					</execution>
   				</executions>
   			</plugin>
   		</plugins>
   	</build>
   </project>
   

2. Install parent POM files into local cache:

   mvn install -f parent-pom-a.pom
   mvn install -f parent-pom-b.pom
   

3. Execute Maven with project-pom.pom

   mvn initialize -f project-pom.pom
