Maven版本插件：更新插件

运行versions：display-plugin-updates时，我看到了一些更新，但插件没有办法修复这些更新。我只是想念什么吗？

这是输出：

The following plugin updates are available:
  maven-checkstyle-plugin ................................ 2.16 -> 2.17
  maven-release-plugin ................................. 2.5.2 -> 2.5.3
  maven-surefire-report-plugin ......................... 2.18.1 -> 2.19
  org.codehaus.mojo:findbugs-maven-plugin .............. 3.0.2 -> 3.0.3

The following plugins do not have their version specified:
  maven-clean-plugin ........................ (from super-pom) 3.0.0
  maven-deploy-plugin ....................... (from super-pom) 2.8.2
  maven-install-plugin ...................... (from super-pom) 2.5.2

Project defines minimum Maven version as: 3.0.4
Plugins require minimum Maven version of: 3.0.4
Note: the super-pom from Maven 3.0.5 defines some of the plugin
      versions and may be influencing the plugins required minimum Maven
      version.

No plugins require a newer version of Maven than specified by the pom.

Require Maven 3.1 to use the following plugin updates:
  org.bsc.maven:maven-processor-plugin .................... 3.1.0-beta1

是否有更新这些插件和/或添加未定义插件的目标？
