snapshotRepository element is available only in distributionManagement (see maven pom XSD here http://maven.apache.org/xsd/maven-4.0.0.xsd ) and in it you define destination repository where snapshots of your project should be released - it has nothing to do with resolving dependencies tho. For snapshot dependencies including parent pom references to be resolved you need to define a dependency repository with snapshots enabled. E.g. [1] worked for me with maven 3.0.2 and I'm pretty sure you won't have problems resolving dependencies (parent or regular) with this configuration with maven 2.2.1 either.
