Non-resolvable parent POM for Could not find artifact and 'parent.relativePath' points at wrong local POM

Question

I am new to maven.

I have one project which I try to build with the maven3.

When I run the command mvn -X clean install I got the error.

I check the pom.xml but cant understand what was the problem. Some lines from my pom.xml is as below.

  1 <?xml version="1.0"?>   2 <project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"   3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">   4   <modelVersion>4.0.0</modelVersion>   5   6 <parent>   7     <groupId>org.openstack</groupId>   8     <artifactId>openstack-rhel-rpms</artifactId>   9     <version>2012.1-SNAPSHOT</version>  10     <relativePath>../openstack-rhel</relativePath>  11 </parent>  12  13     <groupId>org.openstack</groupId>  14     <artifactId>my-tar</artifactId>  15     <version>2012.1-SNAPSHOT</version>  16   <packaging>pom</packaging>  17   <name>my tar</name>  18 

I also check the solution on some question in stackoverflow like Non-resolvable parent POM: Could not find artifact but couldnt help to solve the problem.

If you need more information related to this question, let me know.

Answer 1

I faced the same issue. Setting relative path of the parent in module projects solved the issue.

Use <relativePath>../Parent Project Name/pom.xml</relativePath>
