parseVersion

public static final Version parseVersion(String versionString)

Parses a String into a Version. This expects a version string in the form of "X[.Y[.Z]][anything]". That is a major number, followed optionally by a minor only or a minor + a patch revision, everything after that being completely ignored. For example, the following version strings are valid: - "3.a.2", but note it is considered only a major version since there's a char where minor number should be (parsed into 3.0.0) - "2" (2.0.0) - "3.11" (3.11) - "1.2.3-SNAPSHOT-12.10.2014" (1.2.3) Bad version strings cause an IllegalArgumentException, whereas a null one will cause a NullPointerException.

Parameters:

versionString - the string to parse into a Version.

Returns:

the major.minor.patch Version corresponding to the string.

Throws:

IllegalArgumentException - if the string cannot be correctly parsed into a Version

NullPointerException - if the string is null.
