If you are using version 1.4.1of maven-enforcer-pluginand it is resulting in this error then you need to use an older version of maven-enforcer-plugin. You can find the Maven dependency below :
如果您使用的版本1.4.1中maven-enforcer-plugin，它是造成这种错误，那么你需要使用的旧版本 maven-enforcer-plugin。您可以在下面找到 Maven 依赖项：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-enforcer-plugin</artifactId>
<version>1.3.1</version>
</plugin>
Other versions can be found from the link below.
其他版本可以从下面的链接找到。
https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-enforcer-plugin
https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-enforcer-plugin
Also, check your Maven version. If you are using maven 3.0.xthen you need to use maven-enforcer-plugin 1.4.1.
另外，请检查您的 Maven 版本。如果您正在使用，maven 3.0.x那么您需要使用maven-enforcer-plugin 1.4.1.

one thing that may cause this problem is that in your project in a POM file required java or maven version is set. you should find it... but how ? maybe you couldn't find any enforcer in your project like me ... (I had the same problem and I became confused because enforcer plugin was not defined in my projects POMs, so I couldn't find it).
可能导致此问题的一件事是在您的项目中的 POM 文件中设置了所需的 java 或 maven 版本。你应该找到它……但是怎么找到？也许你在你的项目中找不到像我一样的执行器......（我遇到了同样的问题，我变得很困惑，因为我的项目 POM 中没有定义执行器插件，所以我找不到它）。
enforcer plugin is in your "effective pom"and you should check it. Effective pomis a configuration file made from super pom + project pom. maven use this configuration file to execute the relevant goal. It helps developers to specify minimum configuration detail in his/her pom.xml. Although configurations can be overridden easily.
执行器插件在您的“有效 pom”中，您应该检查它。 有效的 pom是由超级 pom + 项目 pom 组成的配置文件。maven 使用这个配置文件来执行相关目标。它帮助开发人员在他/她的 pom.xml 中指定最低配置细节。尽管可以轻松覆盖配置。
For showing your effective pom there are 2 ways: 1- use maven command, run this command :
为了显示您的有效 pom，有两种方法： 1- 使用 maven 命令，运行以下命令：
mvn help:effective-pom
2- use your IDE : in Maven window right click on your project node and select show effective POM(it depends on your IDE).
2-使用您的IDE：在Maven窗口中右键单击您的项目节点并选择显示有效的POM（这取决于您的IDE）。
after you find what your forces are you can find it in your project and change it. for me, My effective POMhad enforcer plugin which its requireMavenVersion rule for using Java was 1.8. so I changed my project JDK version to 1.8 and luckily the problem was solved.
在你找到你的力量之后，你可以在你的项目中找到它并改变它。对我来说，我的有效 POM有执行器插件，它使用 Java 的 requireMavenVersion 规则是 1.8。所以我将我的项目 JDK 版本更改为 1.8，幸运的是问题解决了。
I hope this answer could help you.
我希望这个答案可以帮助你。

It is possible that someone is enforcing a specific Maven version.
有人可能正在强制执行特定的 Maven 版本。
If you see the following message:
如果您看到以下消息：
[WARNING] Rule 0: org.apache.maven.plugins.enforcer.RequireMavenVersion failed with message: Detected Maven Version: 3.5.4 is not in the allowed range [3.5.2,3.5.2].
[警告] 规则 0：org.apache.maven.plugins.enforcer.RequireMavenVersion 失败并显示消息：检测到的 Maven 版本：3.5.4 不在允许范围内 [3.5.2,3.5.2]。
Then change your maven installation to the something in the specified range. In this example, only version 3.5.2 is allowed.
然后将您的 maven 安装更改为指定范围内的内容。在此示例中，仅允许版本 3.5.2。

I faced the same issue and resolved it by fixing the pom versions. Below command didn't run properly on all the sub pom's which resulted in different pom versions. 'mvn versions:set -DnewVersion=${NEW_VERSION} versions:commit' Check whether all the moms have same version if there is dependent pom's.
我遇到了同样的问题并通过修复 pom 版本解决了它。下面的命令没有在所有子 pom 上正确运行，导致不同的 pom 版本。'mvn versions:set -DnewVersion=${NEW_VERSION} versions:commit' 如果有依赖的pom，检查所有妈妈是否有相同的版本。

I had this problem because Java (java) was version 8 and the Java compiler (javac) was version 11.
我遇到这个问题是因为 Java (java) 是版本 8，而 Java 编译器 (javac) 是版本 11。
This is typical for Windows users, if you need to switch between versions manually.
如果您需要手动在版本之间切换，这对于 Windows 用户来说是典型的。
Please check the versions first:
请先检查版本：
java -version
javac -version
If an IDE is used, for example an IntelliJ Idea, then I will advise to carefully study the project settings as well. Perhaps it makes sense to completely delete the files generated by the IDE and import the project again.
如果使用 IDE，例如 IntelliJ Idea，那么我建议您也仔细研究项目设置。也许完全删除IDE生成的文件并重新导入项目是有意义的。

After doing some research found an answer for this .if your using IntelliJ
在做了一些研究之后找到了答案。如果您使用 IntelliJ
Go to Settings ---> builds --> Maven -->set the Maven home directory.
