我生成默认的quickstart Maven示例,并键入 mvn checkstyle:checkstyle ,它总是尝试使用最新的 SNAPSHOT 2.5 用于checkstyle而不是 2.6-SNAPSHOT ?

C:\HelloWorld>mvn checkstyle:checkstyle
[INFO] Scanning for projects...
[INFO] Searching repository for plugin with prefix: 'checkstyle'.
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Error building POM (may not be this project's POM).

Project ID: org.apache.maven.plugins:maven-checkstyle-plugin

Reason: Error getting POM for 'org.apache.maven.plugins:maven-checkstyle-plugin' from  the repository: Failed to resolve artifact, possibly due to a repository list that is not appropriately equipped for this artifact's metadata.
  org.apache.maven.plugins:maven-checkstyle-plugin:pom:2.6-SNAPSHOT

from the specified remote repositories:
  nexus (http://localhost:9081/nexus/content/groups/public)

for project org.apache.maven.plugins:maven-checkstyle-plugin

mvn checkstyle:2.5:checkstyle 不幸的是,事实并非如此。

pom.xml ,它会工作,但我想看看命令行如何工作。

如果不想运行本地存储库中安装的插件的最新版本,则需要设置版本号。为此,您需要以以下形式指定一个完全限定的目标:

mvn groupID:artifactID:version:goal

所以在你的情况下:

mvn org.apache.maven.plugins:maven-checkstyle-plugin:2.5:checkstyle

我对新版本maven(3.3.9)的体验略有不同。如果我不是在离线模式下运行maven,那么无论我在本地的repo中有什么,它都将用于远程repo。如果它找到一个更新的版本(基于maven metadata.xml),它将下载并使用这个版本。此外,它将同时扫描多个回购:

而且,maven似乎知道如何比较几个元数据文件并选择工件的最新版本。 resolver-status.properties :

您还可以使用:

mvn{your groupId}:{your artifactId}:{your version}:{your goal}
