Error when creating a new maven project

Question

When I try create a new maven project (with several archetypes, not only the one below), I am facing this error:

Unable to create project from archetype [org.apache.maven.archetypes:maven-archetype-quickstart:RELEASE]
Unable to add module to the current project as it is not of packaging type 'pom'

Anyone know why this is happening, and how to solve it?

Answer 1

It seems that your directory is not empty. this command line works for me: (in an empty directory)

mvn archetype:generate -DgroupId=fr.myGroupId -DartifactId=MyApplication -Dpackagename=fr.myGroupId -DarchetypeArtifactId=maven-archetype-quickstart

the result is:

[INFO] Using property: groupId = fr.myGroupId
[INFO] Using property: artifactId = MyApplication
Define value for property 'version':  1.0-SNAPSHOT: : 
[INFO] Using property: package = fr.myGroupId
Confirm properties configuration:
groupId: fr.myGroupId
artifactId: MyApplication2
version: 1.0-SNAPSHOT
package: fr.myGroupId

I can reproduce your error by doing this command line inside the newly created directory:

cd MyApplication
mvn archetype:create -DgroupId=fr.myGroupId -DartifactId=MyApplication -Dpackagename=fr.myGroupId -DarchetypeArtifactId=maven-archetype-quickstart
[...] [INFO] BUILD FAILURE

Answer 2

我遇到了同样的问题，通过手动删除工作区目录根目录下未使用的pom.xml文件解决了

Answer 3

You have to remove the already existing pom.xml or if you need it to execute the maven command, try adding <packaging>pom</packaging> to your pom.

Since if you have an already existing in the current directory, it should match with the package structure. It is always to good to start with no pom file in the parent directory.

This should work.

I was having the same problem using Windows PowerShell in a newly created directory with nothing in it. I tried the command using the regular Windows Command Prompt, and it worked fine.

Answer 5

I simply created new workspace and it worked for me..
