Maven error No POM in this project when executing archetype: generate

Question

I tried my hands in Akka Pi java tutorials

I am trying to create a maven project as indicated in the tutorial

but whenever I enter the command to create the maven project, I get an error. Following are the commands and Error.

C:\Program Files\akka-2.0.2>mvn archetype:generate \ C:\Program Files\akka-2.0.2>mvn archetype:generate \ [INFO] Scanning for projects...

[ERROR] [ERROR] For more information about the errors and possible solutions, please rea d the following articles: [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MissingProject Exception 

it looks like this: maven requests a POM file, but the statutes do not indicate that I should create a POM before creating a project. I'm actually too new, so forgive me. I use version maven: 3.0.4 and version akka 2.0.2 but the tutorial uses version akka 2.0.1, but I don’t think this is a problem, any suggestion please.

Thank you

Answer 1

delete \ , then it should start asking for more information.

I don't have windows here, but on linux it shows the same behavior with

 mvn archetype:generate /

Answer 2

When some tutorials describe the mvn command to be executed, which is covered in two lines or more, they can add an additional backslash in a new line (instructions) to indicate that the same command continues on the next line.

This backslash must be removed BEFORE the command is executed. For example, a command to create a web application in Jersey might look like this:

 mvn archetype:generate -DarchetypeGroupId=org.glassfish.jersey.archetypes \ -DarchetypeArtifactId=jersey-quickstart-webapp -DarchetypeVersion=2.2 

but you should run as below without a backslash:

 mvn archetype:generate -DarchetypeGroupId=org.glassfish.jersey.archetypes -DarchetypeArtifactId=jersey-quickstart-webapp -DarchetypeVersion=2.2 

If you DO NOT remove this extra backslash, you may get the error described above.
