Class VersionNumber

java.lang.Object
  org.jvnet.hudson.maven.plugins.hpi.VersionNumber

All Implemented Interfaces:

Comparable<VersionNumber>

public class VersionNumber
extends Object
implements Comparable<VersionNumber>

Immutable representation of a dot or '-'-separated digits (such as "1.0.1" or "1.0-52"). VersionNumbers are Comparable.

Special tokens

We allow a component to be not just a number, but also "ea", "ea1", "ea2". "ea" is treated as "ea0", and eaN < M for any M > 0.

'*' is also allowed as a component, and '*' > M for any M > 0.

'SNAPSHOT' is also allowed as a component, and "N.SNAPSHOT" is interpreted as "N-1.*"

 2.0.* > 2.0.1 > 2.0.1-SNAPSHOT > 2.0.0.99 > 2.0.0 > 2.0.ea > 2.0
