maven archetype j2ee-simple generates a failing project

Question

I created a j2ee-simple project using the maven template with following command-line

 mvn archetype:create -DgroupId=com.hardik -DartifactId=ActionBazaar -DarchetypeArtifactId=maven-archetype-j2ee-simple

When I try to run the install goal within the created project folder I get an error about not existent model file in the site module. The error is described bellow.

When I remove the site module from the root pom.xml it works. Is there any proper way to correct this problem ?

What if I want to keep the site module in order to make website for my project ?

Here the error:

$ mvn install

Answer 1

Try updating your maven to begin with. Trying to run this myself, I get the following error:

[WARNING] This goal is deprecated. Please use mvn archetype:generate instead

Aside from that, the archetype doesn't seem to even create a site module - if you ls, you'll notice there is, in-fact, no 'site' directory i.e. no module - that's why you're getting the error, and that's why removing the site fixes the problem. You can of course still make a dedicated site module - just create the directory 'site', and put a minimalist pom in there, which will let the build pass.

And, as I thought, here is the associated archetype bug for this issue: MARCHETYPES-15 . I suggest you vote for it, and 'watch' for when it will be fixed.

But like I said, simply adding the 'site' dir with a minimal pom will fix your problem. But you'll have to find a 'site' template as well. I suggest reading this excellent book from Sonatype (the creators of Maven.)

Answer 2

In every module or project in the workspace make sure the and the element in the pom.xml contain the same entries. In this example below it is ad-common. With this it should work.

<artifactId>ad-common</artifactId>
<packaging>jar</packaging>
<version>0.0.1-SNAPSHOT</version>
<name>ad-common</name>
