提问by Oskar Ferm
I get this error in my pom.xml, and I can't understand what I need to change in order to get eclipse to run the project (run as -> maven build)
我在我的 .py 中收到此错误，我pom.xml无法理解我需要更改什么才能让 eclipse 运行该项目（运行方式 -> maven build）

The error when trying to build it from within eclipse is
尝试从 eclipse 中构建它时的错误是
[ERROR] No goals have been specified for this build.

I would really appreciate any help!
我真的很感激任何帮助！

From the error message above, it appears that you have tried the Run as -> Maven Buildwithout specifying which maven goalto run.
从上面的错误消息来看，您似乎在Run as -> Maven Build没有指定goal要运行的maven的情况下尝试了。
You should try a specific maven goal - Run as -> Maven installor Run as -> Maven test.
Alternately, you can provide a goal in the Maven Build configuration.
您应该尝试特定的 Maven 目标 -Run as -> Maven install或Run as -> Maven test. 或者，您可以在Maven Build configuration.
Now, as for the warning, copy-dependencies is not supported by m2e, it means that m2e does not support this plugin. Not all the maven functionality are currently supported by m2e.
现在，至于警告，copy-dependencies is not supported by m2e表示 m2e 不支持此插件。m2e 当前并非支持所有 maven 功能。

To resolve this error all you need to do is copy following code just before your closing tag of build.
要解决此错误，您只需在 build 的结束标记之前复制以下代码。
<pluginManagement>
<plugins>
<!--This plugin's configuration is used to store Eclipse m2e settings only. It has no influence on the Maven build itself.-->
<plugin>
<groupId>org.eclipse.m2e</groupId>

I have the same problem as yours
我和你有同样的问题
When you want to compile your Maven project using m2eclipse plugin, try
当您想使用 m2eclipse 插件编译您的 Maven 项目时，请尝试
Run as -> Maven Build
运行方式 -> Maven 构建
then type compilein Goals
然后在目标中输入编译
