我是靠谱客的博主稳重路灯，最近开发中收集的这篇文章主要介绍maven的依赖版本范围，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

maven项目中所依赖的jar包版本不是唯一特定的版本，可以使用版本范围设定

设定的规则见下表：

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

例子如下：

		<dependency>
			<groupId>org.twitter4j</groupId>
			<artifactId>twitter4j-core</artifactId>
			<version>[2.2,)</version>
		</dependency>
		<dependency>
			<groupId>org.twitter4j</groupId>
			<artifactId>twitter4j-stream</artifactId>
			<version>[2.2,)</version>
		</dependency>

标识依赖版本为>=2.2的jar包
