Answer 1

Close your eclipse
Delete the .m2 folder which shows the server connnection
Re-run your eclipse.

Answer 2

Try this one, it works for maven 3-3-9 for win7 32bit
mvn archetype:generate -DgroupId="com.mycompany.app" -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

Answer 3

Try this :
mvn archetype:generate -DgroupId="com.mycompany.app" -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
Your sentences have been modified -DgroupId="com.mycompany.app". You need to use double quotes.
I´ve worked on windows 8 and it works. I don´t know if it happens on Linux.

Answer 4

I faced the same issue, and I resolved by run the commond(MVN Clean) from inside the folder where pom.xml located. Please follow below steps:
Open Eclipse
Open your Maven project.
Right Click on pom.xml
Click on properties
5.Copy pom.xml location URL
Open cmd
Write and paste the pom.xml location in the cmd until before /pom.xml as below,
cd C:\Users\X\eclipse-workspace\Your project Name
Hit Enter.
Run mvn clean commond again.

Answer 5

You will note that the original error said
Directory my-app already exists - please run from a clean directory
Did you possibly run that command from a directory where there is already a Maven project (one with a pom.xml file)? If so please start with a clean location.
When I ran the command you used verbatim on an empty directory, it ran without error and created a directory called my-app.

Answer 6

This line is of concern:
[INFO] Using following parameters for creating project from Old (1.x)
Archetype: maven-archetype-quickstart:1.0
Looking at the maven docs page at http://maven.apache.org/archetype/maven-archetype-bundles/maven-archetype-quickstart/, i see that the command you should be using is:
mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=5-SNAPSHOT
Which is not exactly what you are running (you are missing the -DarchetypeVersion=5-SNAPSHOT part).
