[BUG] [MVN Plugin] - <templateDirectory> is ignored

Created by: yuvalishay

I'm running mvn install with the following configuration - but the looks like the is ignored and Template directory always defaults to embedded dir.

Here is the maven plugin section in which the templateDirectory is ignored:

  <build>

openapi-generator version

            <groupId>org.openapitools</groupId>
            <artifactId>openapi-generator-maven-plugin</artifactId>
            <version>4.1.3</version>

I tried also earlier from 4.0.0 and above - but still the same.
