Apache Maven Enforcer Built-In Rules – Version Range Specification

Version Range Specification

The RequireMavenVersion and RequireJavaVersion rules use the standard Maven version range syntax with one minor change for ease of use (denoted with *):

Range Meaning
1.0 x >= 1.0 * The default Maven meaning for 1.0 is everything (,) but with 1.0 recommended. Obviously this doesn't work for enforcing versions here, so it has been redefined as a minimum version.
(,1.0] x <= 1.0
(,1.0) x < 1.0
[1.0] x == 1.0
[1.0,) x >= 1.0
(1.0,) x > 1.0
(1.0,2.0) 1.0 < x < 2.0
[1.0,2.0] 1.0 <= x <= 2.0
(,1.0],[1.2,) x <= 1.0 or x >= 1.2. Multiple sets are comma-separated
(,1.1),(1.1,) x != 1.1
