> early versions, we define modules versions with expressions, and set them to
> the parent pom,
> simply;
> {code:xml}
> <properties>
> <ibb-core-cache.version>1.0.1</ibb-core-cache.version>
> <ibb-core-util.version>1.0.1</ibb-core-util.version>
> </properties>
> {code}
> and then, we give this property to modules pom as expression ,
> {code:xml}
> <name>ik-plug</name>
> <packaging>jar</packaging>
> <version>${ibb-core-util.versionn}</version>
> {code}
> but know , it gives an error you know like this,
> {noformat}
> [WARNING] Some problems were encountered while building the effective model
> for ibb-parent:ibb-modules-parent:pom:1.0.0
> [WARNING] 'version' contains an expression but should be a constant. @
> ibb-parent:ibb-modules-parent:${ibb-core-jars.version},
> C:\dev\ibb\workspace\core\ibb-modules-parent\pom.xml
> {noformat}
> but I think that, this enhancement is causes wrong result,
> think that , if we have i project already developing about 3 years, this
> project has a lot of modules, and this modules have sub modules , and this
> sub modules already bound to some other modules not define in your pom, but
> your updates must be affect them, at this situation, developer want to write
> the existing version numbers with properties to parent pom, and want to
> manage them like this. at the attach file below , the close projects are
> belongs to open projects, but they are the different team developing this. I
> cant force the other developers to cache their versions, I must use this
> versions as initial step
