Is there a ${parent.version} scheme or something like that which can be
used instead of the explicitly specifying the version for each dependency?Stephane Frenot (JIRA) escribió: > A better bundle/artifact version numbering scheme > ------------------------------------------------- > > Key: FELIX-155 > URL: http://issues.apache.org/jira/browse/FELIX-155 > Project: Felix > Issue Type: Improvement > Reporter: Stephane Frenot > Priority: Trivial > > > There is an issue with version management. > For the moment many bundles are versionned on the same scheme as > felix framework. ie : 0.8.0-SNAPSHOT > > This is because most of them do not declare a version number in their pom.xml. > > But if you declare a specific version number in you pom.xml there is > an issue, because you cannot use anymore the default $pom.version in your > dependencies.
