Project building exception : Cannot find parent
-----------------------------------------------
Key: MNG-4503
URL: http://jira.codehaus.org/browse/MNG-4503
Project: Maven 2 & 3
Issue Type: Bug
Components: POM
Affects Versions: 2.1.0
Environment: Windows
Reporter: amaresh mourya
Attachments: apache-maven-2.2.0.rar
I ran the org.apache.maven.project.MavenProject build() method from
DeafultMavenProjectBuilder for maven-artifact's pom.xml (A) to build Maven
Project for maven-artifact, but since it is derived from
org.apache.maven:maven:2.2.0 's pom.xml which has parent entry like shown below
(B), and maven-parent is not located at relative path is gives me the following
error (C):
If maven-parent is not available at relative path it should download it from
the central.
1. I haven't touched my local repo.
2. my setting.xml resides at \apache-maven-2.1.0\conf\settings.xml and have
just proxy information
3. I have attached my test case with setting.xml
A: part of maven-artifact's pom.xml
<parent>
<groupId>org.apache.maven</groupId>
<artifactId>maven</artifactId>
<version>2.2.0</version>
</parent>
<artifactId>maven-artifact</artifactId>
