Model classes not detected.

[mdros]

Hello everyone,
I have a following problem: I have a package containing classes, which are written in plain java - the only annotations are from Lombok - and I wanted to document them as models inside yaml file. Is it possible and I am configuring something in the wrong way, or is the plugin not suitable for my case.

  <plugin>
      <groupId>com.github.kongchen</groupId>
      <artifactId>swagger-maven-plugin</artifactId>
      <version>3.1.8</version>
      <configuration>
          <apiSources>
              <apiSource>
                  <springmvc>false</springmvc>
                  <locations>
                      <location>com.sabre.tripcase.tcp.corporation.v2.model</location>
                  </locations>
                  <info>
                      <title>Test</title>
                      <version>1.0</version>
                  </info>
                  <swaggerDirectory>${project.build.directory}/swagger</swaggerDirectory>
                  <attachSwaggerArtifact>true</attachSwaggerArtifact>
                  <outputFormats>yaml</outputFormats>
              </apiSource>
          </apiSources>
      </configuration>
      <executions>
          <execution>
              <phase>compile</phase>
              <goals>
                  <goal>generate</goal>
              </goals>
          </execution>
      </executions>
  </plugin>

Here's the configuration, and here's an example of a file I want to document:

@ApiModel
@ToString
@JsonIgnoreProperties(ignoreUnknown = true)
public class CorporationRQ {

    @ApiModelProperty(value = "name")
    private String name;
    @ApiModelProperty(value = "parentUUID")
    private UUID parentUUID;
    @ApiModelProperty(value = "mapping")
    private List<Mapping> mapping;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public UUID getParentUUID() {
        return parentUUID;
    }

    public void setParentUUID(UUID parentUUID) {
        this.parentUUID = parentUUID;
    }

    public List<Mapping> getMapping() {
        return mapping;
    }

    public void setMapping(List<Mapping> mapping) {
        this.mapping = mapping;
    }

}

When I launch the plugin through mvn compile, I get the following result:

---
swagger: "2.0"
info:
  version: "1.0"
  title: "Test"

I tried chaning @ApiModel to @Api with no success.
Thanks for help!
