I have a lot of builds that use a version number generated by the version number plugin. The property is not available in BM 1.0.5 but it works in version 1.0.3:
Example: Use "create a formatted version number", environment variable "civersion"
Add a shell task:
--> This works well
Add a BM 1.0.5 task:
--> BM complains about the syntax, a value after the equals sign is required.
