Package version example
Package versions (0.0.1) has been added to org.clerezza.utils.rdf.simpletransaction, org.clerezza.utils.jaxrs.requesthandler.The package versions are specified in packageinfo files which are located in the packages themselves (see [1]).
The parent pom (org.clerezza.cms.parent/pom.xml) needs to be adapted to define the class source locations as resource location by adding
<resources>
<resource>
<directory>src/main/java</directory>
<filtering>false</filtering>
<includes>
<include>**/packageinfo</include>
<include>**/package-info.java</include>
</includes>
</resource>
</resources>
within the <build/> configuration
org.clerezza.cms.publishing.core imports both simpletransaction and requesthandler. It specifies in the pom.xml a version range according to its usage of these packages. The version range of simpletransaction is [0.0,0.1), because it implements the Commitable interface, and therefore would break if this interface would be extended. The version range of requesthandler is [0.0,1.0), because it only uses the requesthandler API and does not implement anything of it. See [3] for the semantic meaning of version number changes.
