IntelliJ, Maven, Flexmojos - Failed to generate Flex compiler configuration file - maven

Question

I'm running a multi-project build in IntelliJ setup with Flexmojos.
All of the flex modules have a common parent pom file which is downloaded from Artifactory. This dependency seems to be resolved properly but when I hit "Reimport All Maven Projects", or do changes to any child pom file, I get an error
Flexmojos Project Import
**Failed to generate Flex compiler configuration file.**
The pipe has been ended
Flexmojos Project Import
**Failed to generate Flex compiler configuration file.**
exit code: 1
Globals (using maven 'defines' tag) defined in the parent pom are not visible in any child project and if I go into "Project Structure" there is
"Build configurations '[child artifactId]': additional compiler configuration file not found: [absolute path]"
, which is a symptom of the missing configuration files.
I think it is a settings (IntelliJ? Maven? Java?) issue because my colleague has the same code from SVN and does not have the same issue.
Any clues as to where to start looking?

EDIT:
A typical child pom file has no build tag, it is supposed to inherit it from the base pom, they still have packaging 'swc' though.
Base pom has:

Answer 1

It is bug due to "The switch in the core from Sonatype Aether to Eclipse Aether." since maven 3.1. Please watch&vote http://youtrack.jetbrains.com/issue/IDEA-112107.

Answer 2

I just hit the same problem. The java.lang.NoClassDefFoundError: org/sonatype/aether/RepositorySystemSession is the issue and generated when you configure Intellij to use Maven v3.1.0 which doesn't include this library. Roll back to using Maven 3.0.5 with your flexmojos project to get this working.

Answer 3

The issue is that the Flex Maven plug-in no longer generates the additional configuration file by default. I'm not sure if that is a Flex or a Maven thing. The easier solution I found is to tell the plug-in to generate the configuration file with the configurationReport flag:
mvn clean install -DconfigurationReport=true
This works with Maven 3.5.2.
I hope no one else in the world is still using Flex, and no one ever needs this information again. I should change my title to either Senior Code Janitor or Senior Software Necromancer.
