Method Detail

createGemVersion

public String createGemVersion(String mavenVersion)
                        throws NullPointerException

Creates valid GEM version out of Maven2 version. Gem versions are "stricter" than Maven versions: they are in form of "x.y.z...". They have to start with integer, and be followed by a '.'. You can have as many like these you want, but Maven version like "1.0-alpha-2" is invalid Gem version. Hence, some trickery has to be applied.

Parameters:

mavenVersion -

Returns:

Throws:

NullPointerException
