I'm new on Maven and there's something wrong when I try to create a now project.

E:\java\MavenTest>mvn archetype:generate -DgroupId=com.mycompany.app -DartifacId
=my_app -DarchetypeArtifacId = maven_archetype_quickstart -DinteractiveMode=fals

The pom.xml should be generated automatically. But it does not work.

Any help will be highly appreciated.

Answer 1

The root cause are as the following: -

1. There is a space at -DarchetypeArtifacId = maven_archetype_quickstart
2. The archetypeArtifacId should be maven-archetype-quickstart
3. The -DarchetypeArtifacId is miss spelling, the correct is -DarchetypeArtifactId

Then please try the following: -

mvn archetype:generate 
    -DgroupId=com.mycompany.app 
    -DartifactId=my_app 
    -DarchetypeGroupId=org.apache.maven.archetypes 
    -DarchetypeArtifacId=maven-archetype-quickstart 
    -DarchetypeVersion=1.1 
    -DinteractiveMode=false

Please type above command in the single line.

I hope this may help.

Answer 2

Another answer will be related to the console that you are using to generate the maven project with the archetype:

For example: With Powershell, the command of the answer doesn't work but with this command is working properly

mvn archetype:generate 
    "-DgroupId=com.mycompany.app 
    -DartifactId=my_app 
    -DarchetypeGroupId=org.apache.maven.archetypes 
    -DarchetypeArtifacId=maven-archetype-quickstart 
    -DarchetypeVersion=1.1 
    -DinteractiveMode=false"

because of the problems passing the arguments to the maven command.

This is gonna help somebody, it works for me!
