Integrate jQAssistant in Maven build using profile and running server - maven

Question

I'm trying to integrate jQAssistant into my existing Maven build. I have a hierarchy of POMs, but basically the top POM defines what the build does. That's where I have my <pluginManagement> and my build plugins that are always used. I also have a couple of Maven profiles for special builds.
So, I want to scan all classes during build time and aggregate the results into a running server to have a fully populated Neo4J database after the build of all my Maven modules. The database should contain my whole code base.
Analysing and checking would be a different step, I don't want to do that directly when building a Maven module.
The examples I see all build a local database and then check the classes against it. As far as I understand it, I would have to run the server as a daemon and then configure the Maven plugin to use the 'bolt' URI to populate it - is this right?
Also, since I don't want to slow down the 'normal' build, I added a Maven profile to active the jQAssistant scan. However, this only works on my top POM, but doesn't work in any other Maven project/module. The inheritance of profiles is a normal and expected Maven feature - so what am I doing wrong?
Here's my parent POM. Just to see whether the profile is active, I added PMD as well:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</project>
When I run mvn clean package -P architecture on a Maven project with that parent POM, I see the following output, which shows that the profile is active:
09:30:12.316 [INFO]
09:30:12.316 [INFO] --- maven-pmd-plugin:3.5:pmd (default) # util-type ---

09:30:15.976 [INFO]
However, jqassistant-maven-plugin is nowhere.
Now, if I add it to my normal <build> plugins:
<build>
<plugins>
<plugin>
<groupId>com.buschmais.jqassistant</groupId>
<artifactId>jqassistant-maven-plugin</artifactId>
<executions>
<execution>

<goals>
<goal>scan</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
then I see the following output for mvn clean package for my parent POM:
10:38:14.252 [INFO] --- jqassistant-maven-plugin:1.5.0:scan (scan) # parent ---

However, in my Maven project, I don't see any jQAssistant output.
Starting mvn help:effective-pom -Parchitecture gives me the same output for the parent project and the Maven module:

Answer 1

In my projects I have a parent POM with the following plugin management section:
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>com.buschmais.jqassistant</groupId>
<artifactId>jqassistant-maven-plugin</artifactId>
<version>${jqassistant.version}</version>
<configuration>
<useExecutionRootAsProjectRoot>true</useExecutionRootAsProjectRoot>
</configuration>
<executions>
<execution>
<id>scan</id>
<goals>
<goal>scan</goal>
</goals>
</execution>
<execution>
<id>analyze</id>
<goals>
<goal>analyze</goal>
</goals>
<configuration>
<failOnSeverity>MAJOR</failOnSeverity>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</pluginManagement>
</build>
I also defined the following profile, which I use to run jQAsssistant:
<profile>
<id>verify-architecture</id>
<build>
<plugins>
<plugin>
<groupId>com.buschmais.jqassistant</groupId>
<artifactId>jqassistant-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</profile>
Using mvn -P verify-archicture clean install I can scan and analyze my projects.

Answer 2

Here we are, some years later :-)
And coming back to my mistake!
The problem here was the Maven phase. The jQAssistant plugin Mojo scan has the Maven phase post-integration-test by default.
However, we never do mvn clean install in my company, we only do mvn clean package and install using Jenkins, Nexus etc. etc.
So, it was my fault to not force the plugin to the package phase.
That's how it works:
<profile>
<id>jqassistant</id>
<build>
<plugins>
<plugin>
<groupId>com.buschmais.jqassistant</groupId>
<artifactId>jqassistant-maven-plugin</artifactId>
<executions>
<execution>
<id>scan-software</id>
<phase>package</phase>
<goals>
<goal>scan</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</profile>
