I have installed maven 2 and following the tutorial as mentioned in the below link
maven.apache.org/guides/getting-started/maven-in-five-minutes.html
But while executing the archetype:generate command,
mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false"
I am getting the below error
[INFO] Trace

For information,
I am using Sun OpenJDK 1.6.0, Maven 2 and Xubuntu platform.
Any suggestive help on the above error will be appreciated.
Thanks,

It looks like there is a problem with folder access.. Check if the folder where your are trying to create a project is write protected? If it is so, then change its permission to 777 and check if it works.
I had also faced the same issue, still I had all the required permissions to create the folder and files. But it turned out that there was an error in archetype.xml - I was trying add a folder without any files in it -
<testResources>
<resource>src/test/resources/</resource>
</testResources>
After correcting archetype.xml, I got the build succeeded.
Yes, its definitely the permission error. Spent 2 days on it and simply rectified it using sudo :D
I had the same error :D, and what I did was modifying the permission of the folder in which I was creating my project folder (in you case 'my-app'). Indeed, I was just following the maven tutorial's guidelines when I came into this error.
Changing '/usr/local/apache-maven/' folder permission to 775 or to 777 should make it!
