Kie-Maven-Plugin is not working, unable to compile rule artifacts

I am doing a sample hello world maven project using drools version 6.0.0.Final. Below is the build of my pom file, i have specified the kie-maven-plugin but i can notice that this plugin couldnt get executed. Is there anything i am missing here. 

<build>
        <plugins>
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.1</version>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.kie</groupId>
                <artifactId>kie-maven-plugin</artifactId>
                <version>${kieVersion}</version>
                <extensions>true</extensions>
            </plugin>
        </plugins>
        </build>

This is quite an old topic but I just had the same issue, and found nothing to help me. In my case, it was not a configuration error, but a rule synthax error.

I had something like :

when $a : A(status == Status.OK, $val = val)

Instead of : 

when $a : A(status == OK, $val : val)

Changing the " = " to " : " fixed it. I don't know why it refered to KIE though.

Got the same problem with 6.3.0. Here is the code I'm using to activate the drools compilation : 

<plugin>
    <groupId>org.kie</groupId>
    <artifactId>kie-maven-plugin</artifactId>
    <version>6.3.0.Final-redhat-9</version>
    <extensions>true</extensions>
    <executions>
        <execution>
            <id>brms-rules-compilation</id>
            <phase>generate-resources</phase>
            <goals>
                <goal>build</goal>
            </goals>
            <inherited>false</inherited>
            <configuration>
            </configuration>
        </execution>
    </executions>
</plugin>

I had to specifically tell Maven to execute the build goal during generate-resources phase to get a plugin console output : 

[INFO] --- kie-maven-plugin:6.3.0.Final-redhat-9:build (brms-rules-compilation) @ myProject ---
[main] INFO org.drools.compiler.kie.builder.impl.KieRepositoryImpl - Adding KieModule from resource [.....]

I know it is an old question, but did you specify the correct packaging?

<project xmlns="http://maven.apache.org/POM/4.0.0" >
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.foo</groupId>
    <artifactId>fighting</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>kjar</packaging>

Together with using the kie-maven plugin?

Your config looks ok, but you might hit some missing plugin dependencies.

Using the latest version of the kie-maven-plugin (6.0.3-redhat-4) it does pre-compile the drl/xls etc.. rules inside the module into the jar. You can find the precompiled content in the jar if you crack it open - yourmodule-version.jar/META-INF/defaultKieBase/kbase.cache.

You should also see, as maven is building, the kie-maven-plugins "build" output on the console - just to check it is executing.
