I am trying to generate Jersey glassfish project with the aid of maven prompt but when I type the following:
我正在尝试借助 Maven 提示生成 Jersey glassfish 项目，但是当我键入以下内容时：
D:\maven>mvn archetype:generate -DarchetypeGroupId=org.glassfish.jersey.archety
pes -DinteractiveMode=false \ -DarchetypeVersion=2.17
I am getting this error:
我收到此错误：
The goal you specified requires a project to execute but there is no POM in this directory (D:\maven). Please verify you invoked Maven from the correct directory. -> [Help 1]
您指定的目标需要一个项目来执行，但在此目录 (D:\maven) 中没有 POM。请验证您从正确的目录调用了 Maven。-> [帮助 1]
I dont understand the error: Which project is required here since I am trying to generate one? And how should I create the pom.xml file? I thought it is created by the project generation.
我不明白错误：因为我试图生成一个项目，所以这里需要哪个项目？我应该如何创建 pom.xml 文件？我以为它是由项目生成创建的。
I appreciate any help.
我很感激任何帮助。
Editwhen I type it without \
当我没有输入时进行编辑\

I'll go for an answer now.
我现在去找答案。
So the first part of your problem was the caracter "\". See this thread
所以你的问题的第一部分是字符“\”。看到这个线程
Then for your second problem : it is said The desired archetype does
not exist. This archetype maven-archetype-quickstart doesn't exist in maven repository. Please refer to this linkto choose the archetype you are looking for and put it in your command.
那么对于你的第二个问题：据说 The desired archetype does
not exist。这个原型 maven-archetype-quickstart 在 maven 存储库中不存在。请参阅此链接以选择您正在寻找的原型并将其放入您的命令中。
At the end you command must have at least 2 argument -DarchetypeGroupIdand -DarchetypeArtifactId. For example :
最后，您的命令必须至少有 2 个参数-DarchetypeGroupId和-DarchetypeArtifactId. 例如 ：
mvn archetype:generate -DarchetypeGroupId=org.glassfish.jersey.archetypes -DarchetypeArtifactId=jersey-quickstart-webapp
