The main pom file receives the version value as a maven command-line argument.
What I want to achieve is to prevent the build from executing if the argument is either non-existing in the command (not passed), or if it has empty string value, something like -DbuildVersion= or -DbuildVersion="".
The reason is that the generated JARs should not end up without the version number, or worse - with the dummy value set in the buildVersion property.
================= Solution: For anyone having the similar need - use Maven Enforcer Plugin. http://maven.apache.org/enforcer/enforcer-rules/requireProperty.html
I was going to suggest the Maven Enforcer plugin (http://maven.apache.org/enforcer/maven-enforcer-plugin/), but it seems that it's not possible yet -> Run Maven Enforcer Plugin rule on command line. Wouldn't be fine for you to wrap the build process in a scrip that would make that validation for you?
