This is my pom.xml. I am trying to Run my application as Run as-> mvn build from eclipse.
这是我的 pom.xml。我正在尝试将我的应用程序作为 Run as-> mvn build from eclipse 运行。

It sounds like you've accidentally set the wrong goal when trying to build from Eclipse. Edit your Maven "Run as.." settings like so:
听起来您在尝试从 Eclipse 构建时不小心设置了错误的目标。像这样编辑你的 Maven “Run as..” 设置：
Note the clean installwhich will run the Maven commands to clean your build and do a full build and install into the local repository.
请注意clean install，它将运行 Maven 命令来清理您的构建并执行完整构建并安装到本地存储库中。

Try mvn installinstead of mvn build. buildis not a valid option for Maven. You can find a list of valid options in the error message above.
尝试mvn install代替mvn build. build不是 Maven 的有效选项。您可以在上面的错误消息中找到有效选项的列表。
If you just want to compile the sources, try mvn compilebut that will usually produce an incorrect result when you have more than one pom.xmlfile in your project.
如果您只想编译源代码，请尝试，mvn compile但是当您的项目中有多个pom.xml文件时，这通常会产生不正确的结果。

You should build : install , not build : mvn install ,not start with mvn ...
您应该构建：安装，而不是构建：mvn install，而不是从 mvn 开始...

All ides ( Eclipse, Intellij etc.) have some problems with maven build, instead of using bundled maven component, use command-line maven. In command line ( windows or linux console does not matter.) mvn clean, then mvn install will fix your problem. Command line usage can be change your view point of maven.
所有 ide（Eclipse、Intellij 等）在 maven 构建方面都有一些问题，而不是使用捆绑的 maven 组件，而是使用命令行 maven。在命令行（Windows 或 linux 控制台无关紧要。） mvn clean，然后 mvn install 将解决您的问题。命令行的使用可以改变你对 maven 的看法。

It is most probable you set incorrect goals in the configuration when you ran "run as" "Maven build" and now can't change it.
当您运行“作为”“Maven 构建”运行时，很可能您在配置中设置了不正确的目标，现在无法更改它。
Right click on the project -> run as -> Run configurations.
右键单击项目 -> 运行方式 -> 运行配置。

This will bring back up the window you first had on your first build and you can then follow the instructions of the more experienced contributors above.
这将带回您在第一次构建时最初使用的窗口，然后您可以按照上述更有经验的贡献者的说明进行操作。
Hope this helps.
希望这可以帮助。

I also had the same problem, uninstall the GIT bash and install again. This will resolve EnvVar issue is any.
我也有同样的问题，卸载 GIT bash 并重新安装。这将解决 EnvVar 问题。
If still not solved, please check with your commands. Copy and paste your commands from notepad and this should work
如果仍未解决，请检查您的命令。从记事本复制并粘贴您的命令，这应该可以工作

错误：org.apache.maven.lifecycle。LifecyclePhaseNotFoundException有关错误和可能的解决方案的更多信息，请阅读以下文章： [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/ LifecyclePhaseNotFoundException
Solution: Unknown lifecycle phase or wrong goal example:First I am using "clean package tea-container-test:tomcat-test -P "XXX" -e" as goal?, then I changed a goal as "test -P XXX" , then It works perfectly,so Please check , your goal is right or wrong. "Creates a new exception to indicate that the specified lifecycle phase is not defined by any known lifecycle".
解决方案：未知的生命周期阶段或错误的目标示例：首先我使用“clean package tea-container-test:tomcat-test -P "XXX" -e”作为目标？，然后我将目标更改为“test -P XXX” ，然后它完美地工作，所以请检查，你的目标是对还是错。“创建一个新异常以指示指定的生命周期阶段未由任何已知生命周期定义”。
