Hi all,
My first message was rejected as s p a m sob sob.
I have a problem regarding relativePaths, inheritance and aggregation, and
need some help please. I tested this in maven 2.0.5
I have the following directory structure
main:
- pom.xml
parent:
- pom.xml
son:
- pom.xml
- grandson:
- pom.xml
Inheritance goes like this: parent > son > grandson; and aggregation goes
like: main < son and son < grandson.
Whenever I make a fresh mvn install (fresh meaning my local repository is
clean w/o anyone of my artifacts) from the main I get and error because son
artifact cant find the parent POM. I'm using relativePath to indicate where
the son should search for his parent.
Here is the code:
Main pom:
<?xml version="1.0" encoding="UTF-8"?>
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>org.migs.ejemplos</groupId>
<artifactId>maven-test</artifactId>
<version>0.0.1</version>
<packaging>pom</packaging>
<modules>
<module>son</module>
</modules>
</project>
Parent 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
http://maven.apache.org/maven-v4_0_0.xsd";>
<modelVersion>4.0.0</modelVersion>
<groupId>org.migs.ejemplos</groupId>
<artifactId>parent</artifactId>
<packaging>pom</packaging>
<version>0.0.1</version>
</project>
Son pom:
<?xml version="1.0" encoding="UTF-8"?>
<project>
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId> org.migs.ejemplos</groupId>
<artifactId>parent</artifactId>

<relativePath>../parent/pom.xml</relativePath>
</parent>
<groupId> org.migs.ejemplos</groupId>
<artifactId>son</artifactId>
<version>0.0.1</version>
<packaging>pom</packaging>
<modules>
<module>grandson</module>
</modules>
</project>
Grandson POM:
<?xml version="1.0" encoding="UTF-8"?>
<project>

<parent>

The thing is when I comment the aggregation part on the son pom (comment the
modules section) the main installs correctly, or obviously if I install the
parent first. But I think this should build from
the main pom just right.
Thanks
Miguel
