當試圖將swagger併入我的API時，我遇到了一些問題。供應商io.swagger.scala.converter.SwaggerScalaModelConverter無法實例化
我的API使用的是Jersey 2.22，語言是Scala。我已經添加了以下依存關係到我的POM：
<dependency>
<groupId>io.swagger</groupId>
<artifactId>swagger-annotations</artifactId>
<version>1.5.12</version>
</dependency>
<dependency>
<groupId>io.swagger</groupId>
<artifactId>swagger-scala-module_2.11</artifactId>
<version>1.0.3</version>
</dependency>
我的插件配置如下：
<plugin>
<groupId>com.github.kongchen</groupId>
<artifactId>swagger-maven-plugin</artifactId>
<version>${kongchen.plugin.version}</version>
<executions>
<execution>
<phase>compile</phase>
<goals>
<goal>generate</goal>
</goals>
</execution>
</executions>
<configuration>
<apiSources>
<apiSource>
<locations>${swagger.locations}</locations>
<springmvc>false</springmvc>
<host>${swagger.host}</host>
<basePath>${base.path}</basePath>
<info>
<title>${swagger.title}</title>
<version>${project.version}</version>
<description>${swagger.description}</description>
</info>
<swaggerDirectory>${project.build.directory}/</swaggerDirectory>
<outputFormats>yaml,json</outputFormats>
</apiSource>
</apiSources>
</configuration>
</plugin>
當我跑步時MVN編譯，出現以下錯誤：

如果我遺漏了scala-swagger模塊，編譯工作正常，我得到一個有效的json（所有資源描述都完美生成），但scala case類中的字段不會生成：
@ApiModel("some model")
case class HelloModel(@(ApiModelProperty @field)(dataType = "Int", value = "some int", name = "tries") tries: Int)
結果：
"definitions" : {
"some model" : {
"type" : "object"
}
}
任何人都得到了線索？
