Maven: Specifying project versions in pom.xml file

Every project has a version number associated with it. Project version format looks like below.

<majorVersion>.<minorVersion>.<incrementalVersion>-<qualifier>

<qualifier> is used to specify milestone builds like alpha and beta releases

Example 1

19.5.1-alpha-01

majorVersion : 19

minorVersion : 5

incrementalVersion : 1

qualifier : alpha-01

Example 2

19.5-beta-05

majorVersion : 19

minorVersion : 5

qualifier : beta-05

Version ’10.4.1’ is greater than ’10.3.20’. When all the version numbers are in integers, then comparison made using integers of the major, minor and incremental versions.

If version number contains non-numerals too, then string comparison is used to compare versions. For example, ‘1.2.5b’ and ‘1.3.4a’ are compared using string companions.
