Jason van Zyl updated MNG-1803:
-------------------------------
Fix Version/s: (was: 3.x)
3.0-alpha-7
This is a lot better in 3.0, but we could still provide more assistance:
currently it looks like this:
bash-3.2$ mvn validate
[INFO] Scanning for projects...
[ERROR] The build could not read 1 project -> [Help 1]
[ERROR] The project org.apache.maven:maven-core:3.0-SNAPSHOT
(/Users/jvanzyl/js/org/apache/maven/maven-3/trunk/maven-core/pom.xml) has 1
error
[ERROR] 'dependencies.dependency.version' must be a valid version for
commons-jxpath:commons-jxpath:jar but is '${jxpathVersion}'.
[ERROR]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e
switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
[ERROR]
[ERROR] For more information about the errors and possible solutions, please
read the following articles:
[ERROR] [Help 1]
http://cwiki.apache.org/confluence/display/MAVEN/ProjectBuildingException
But we could add the line/column as well.
