I don't know what you mean by 'version of plugin installed' but the Maven help pluginenables you to get the desciption of a plugin by giving the groupId and artifactId,
我不知道您所说的“已安装插件的版本”是什么意思，但是Maven 帮助插件使您能够通过提供 groupId 和 artifactId 来获取插件的描述，
mvn -Dplugin=<groupId>:<artifactId> help:describe
You will get a detailed description of the plugin - including the version (although I must admit that I don't know the strategy of version number resolving).
你会得到插件的详细描述——包括版本（虽然我必须承认我不知道版本号解析的策略）。
Examplefor the maven-dependency-plugin
maven-dependency-plugin 的示例
mvn -Dplugin=org.apache.maven.plugins:maven-dependency-plugin help:describe
Output:
输出：
Name: Maven Dependency Plugin
Description: Provides utility goals to work with dependencies like copying,
unpacking, analyzing, resolving and many more.
Group Id: org.apache.maven.plugins
Artifact Id: maven-dependency-plugin
Version: 2.2
Goal Prefix: dependency
This plugin has 21 goals:
dependency:analyze
Description: Analyzes the dependencies of this project and determines which
are: used and declared; used and undeclared; unused and declared. This goal
is intended to be used standalone, thus it always executes the test-compile
phase - use the dependency:analyze-only goal instead when participating in
the build lifecycle.
dependency:analyze-dep-mgt
Description: This mojo looks at the dependencies after final resolution and
looks for mismatches in your dependencyManagement section. In versions of
maven prior to 2.0.6, it was possible to inherit versions that didn't match
your dependencyManagement. See MNG-1577 for more info. This mojo is also
useful for just detecting projects that override the dependencyManagement
directly. Set ignoreDirect to false to detect these otherwise normal
conditions.
dependency:analyze-duplicate
Description: Analyzes the <dependencies/> and <dependencyManagement/> tags
in the pom.xml and determines the duplicate declared dependencies.
... and much more

Add this to your pom.xmlfile and you will get the result on mvn clean install:
将此添加到您的pom.xml文件中，您将获得以下结果mvn clean install：
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>versions-maven-plugin</artifactId>
<version>2.1</version>
<executions>
<execution>
<phase>validate</phase>
<goals>
<goal>display-dependency-updates</goal>
<goal>display-plugin-updates</goal>
<goal>display-property-updates</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
If you just want to do it once:
如果你只想做一次：
mvn versions:display-plugin-updates

You can add an "-X" parameter when maven is packaged(mvn clean compile * -X), and then search for "artifactId" to see the exact version number.
可以-X在maven打包的时候加一个" "参数( mvn clean compile * -X)，然后搜索" artifactId"查看确切的版本号。
