Used this plugin in existing spring boot project, I used same plugin with non spring boot project and it's working perfect.

Plugin used in POM is as follows, 

<plugin>
    <groupId>com.github.kongchen</groupId>
    <artifactId>swagger-maven-plugin</artifactId>
    <version>3.1.7</version>
    <configuration>
        <apiSources>
            <apiSource>
                <springmvc>true</springmvc>
                 <basePath>/</basePath>
                <locations>com.project</locations>
                <schemes>http,https</schemes>
                <!-- <basePath>/api</basePath> -->
                <info>
                    <title>MyService</title>
                    <version>${project.version}</version>
                </info>
                <swaggerDirectory>swagger</swaggerDirectory>
            </apiSource>
        </apiSources>
    </configuration>
</plugin>

Error as follows,
