    <configuration>

        <classResourceNames />
        <outputFileName>${project.artifactId}</outputFileName>
        <!-- NOTE: terminate packages with dots otherwise scanning yields nothing -->
        <basePackages>com.cb4.base.rest.,com.cb4.cretail.rest.,com.cb4.cpatterns.rest.</basePackages>
    </configuration>
</plugin>

this is due to the following code:
 

org.apache.cxf.common.util.SpringClasspathScanner#findClassesInternal

 for (final String basePackage: basePackages) {
            final boolean scanAllPackages = basePackage.equals(WILDCARD);
            final String packageSearchPath = ResourcePatternResolver.CLASSPATH_ALL_URL_PREFIX
                + (scanAllPackages ? "" : ClassUtils.convertClassNameToResourcePath(basePackage))
                + ALL_CLASS_FILES;

ClassUtils.convertClassNameToResourcePath(basePackage)

only converts '.' to '/', and since

    public static final String ALL_FILES = "**/*";
    public static final String ALL_CLASS_FILES = ALL_FILES + ".class";

so foo.bar.baz becomes classpath*:foo/bar/baz**/*.class instead of classpath*:foo/bar/baz/**/*.class
