Why does not archetype:generate with parameters work for me?

Question

If i run mvn archetype:generate it works but if i try

mvn archetype:generate -DarchetypeGroupId org.codehaus.mojo -DarchetypeArtifactId gwt-maven-plugin  -DarchetypeVersion=2.5.0 

The message is from my last attempt with backslashes but it''s the same message for without slashes command

E:\mavenplay\a>mvn archetype:generate \ -DarchetypeGroupId org.codehaus.mojo \ -
DarchetypeArtifactId gwt-maven-plugin \ -DarchetypeVersion=2.5.0 -X

I have tried with / \ and no slashing. Please
let me know what other details to give.

LE: As a sidenote i did manage to create the archetype in interactive mode of course but i'm just curious why it does not work directly

Answer 1

If you are using a Windows shell you need to put quotes around the arguments like this:

mvn archetype:generate "-DarchetypeGroupId=org.codehaus.mojo" "-DarchetypeArtifactId=gwt-maven-plugin" "-DarchetypeVersion=2.5.0"

Thanks to the poster here for pointing this out.
