# Class: com.pnfsoftware.jeb.core.Version

Version number object. The syntax is as follows: `major.minor.buildid.timestamp.channel` or `major.minor-channelString.buildid.timestamp`. 

 Details:
 \- A valid version string must contain the fields `major`, `minor` and `buildid`
 \- Timestamp format: `YYYYMMDDhhmm`
 \- Allowed channels: `RELEASE(0,"")`, `BETA(1,"beta")`, `ALPHA(2,"alpha")`
 

 Examples of valid version strings: 

```

 1.0.0
 1.0.2.201801021400
 1.0.2.201801021400.0
 1.0.2.201801021400.1
