A Maven SNAPSHOT is an artifact created by a Maven build and pretends to help developers in the software development cycle. A SNAPSHOT is an artifact (or project build result ) that is not pretended to be used anywhere, it's only a temporarily .jar, ear, ... created to test the build process or to test new requirements that are not yet ready to go to a production environment. After you are happy with the SNAPSHOT artifact quality, you can create a RELEASE artifact that can be used by other projects or can be deployed itself.

在你的项目中，你可以使用Maven的pom.xml文件中的version元素定义一个SNAPSHOT:

<groupId>example.project.maven</groupId>
<artifactId>MavenEclipseExample</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<description>Maven pom example</description>

“快照”术语意味着构建是给定时间内代码的快照。

这通常意味着这个版本仍在大量开发中。

当代码准备好并且是时候发布它时，您将希望更改POM中列出的版本。然后，您将使用“1.0”这样的标签，而不是使用“SNAPSHOT”。

“发行版”是一个没有更改的版本的最终版本。

“快照”是一个可以被具有相同名称的另一个构建所替换的构建。这意味着构建可以在任何时候更改，并且仍然处于积极的开发中。

对于基于相同代码的不同构建，您有不同的工件。例如，你可能有一个调试和一个没有。一个用于Java 5.0，一个用于Java 6。一般来说，一个版本能满足你所有的需求会更简单。；）

快照仅仅意味着Maven将根据您的配置检查特定依赖项的最新更改。快照是不稳定的，因为它是在开发中，但如果在一个特殊的项目需要有最新的变化，你必须配置你的依赖版本为快照版本。这种情况发生在拥有多个产品的大型组织中，这些产品彼此密切相关。

understanding the context of SDLC will help understand the difference between snapshot and the release. During the dev process developers all contribute their features to a baseline branch. At some point the lead thinks enough features have accumulated then he will cut a release branch from the baseline branch. Any builds prior to this time point are snapshots. Builds post to this point are releases. Be noted, release builds could change too before going to production if any defect spot during the release testing.
