我在执行mvn versions:display-plugin-updates时遇到以下错误。基于this discussion,该问题已在2.6中修复,但我使用的是2.7(尝试使用2.6,但未成功)。

[ERROR] Project does not define required minimum version of Maven.
[ERROR] Update the pom.xml to contain maven-enforcer-plugin to
[ERROR] force the Maven version which is needed to build this project.
[ERROR] See https://maven.apache.org/enforcer/enforcer-rules/requireMavenVersion.html
[ERROR] Using the minimum version of Maven: 3.0.5

这是我的<pluginManager>插件:

<pluginManagement>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-enforcer-plugin</artifactId>
      <version>3.0.0-M2</version>
      <executions>
        <execution>
          <id>enforce-versions</id>
          <goals>
            <goal>enforce</goal>
          </goals>
          <configuration>
            <rules>
              <requireMavenVersion>
                <version>3.5.4</version>
              </requireMavenVersion>
            </rules>
          </configuration>
        </execution>
      </executions>
    </plugin>
    <plugin>
      <groupId>org.codehaus.mojo</groupId>
      <artifactId>versions-maven-plugin</artifactId>
      <version>2.7</version>
      <configuration>
        <generateBackupPoms>false</generateBackupPoms>
      </configuration>
    </plugin>
  </plugins>
</pluginManagement>

即使给定插件具有pluginManagement,您仍需要在pom的build-> plugins部分中声明该插件,配置才能生效。而某些插件,例如maven-compiler-plugin默认添加到项目中,maven-enforcer-plugin显然不是这种情况(如您的实验所示)。

我不确定是否有不需要显式添加的插件列表,但是我认为它是最常见的插件,例如maven-surefire-plugin和maven-clean-plugin。
