Maven does not create persistence.xml file

Question

I am reading this article on the maven project web page, which lists various directory layouts (for example: src / main / resources, which is for application / Library resources).

The problem is that when I run the following command ( found here ):

mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

the src / main / resources / META-INF directory is not created. This is important to me because I would like to get "persistence.xml" which is in this directory.

Should I add a parameter to the mvn command? How can I automatically generate "src / main / resources" that contains the META-INF / persistence.xml file?

Thanks, Relationship

The problem is that the following command (...) does not create the src / main / resources / META-INF directory. This is important to me because I would like to get "persistence.xml" which is in this directory.

The maven quick launch archetype does not create src/main/resourcesand src/test/resources. There are several explanations:

• As indicated by its name, this archetype allows you to quickly launch a project, but you need to form it.
• Why src/main/resourcesdoes this archetype create and not, say src/main/assembly,?
• Creating empty directories is actually not possible for a long time (see ARCHETYPE-57 ).

mvn? "src/main/resources", META-INF/persistence.xml?

Here you used the quickstart archetype, which is an example, more details here . If you want the standard Java EE layout, you use the maven-archetype-j2ee-simplearchetype:

mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-j2ee-simple -DinteractiveMode=false
