所以这对我来说是 codegen101，我一直在尝试使用 swagger 插件并不断出错。这是一个已知问题吗，我已经尝试了插件的多个版本，认为这可能是其中一个已知问题，但根本没有成功。这应该是非常直接的练习。我不确定我错过了什么。有人可以指出吗

 <build>
    <plugins>
      <plugin>
        <groupId>io.swagger.codegen.v3</groupId>
        <artifactId>swagger-codegen-maven-plugin</artifactId>
        <version>3.0.18</version>
        <executions>
          <execution>
            <goals>
              <goal>generate</goal>
            </goals>
            <configuration>
              <inputSpec>${project.basedir}/src/main/resources/service-api.yaml</inputSpec>
              <language>java</language>
              <output>${project.build.directory}/generated-sources/</output>
              <generateSupportingFiles>false</generateSupportingFiles>
              <apiPackage>com.openapi101.api</apiPackage>
              <modelPackage>com.openapi101.models</modelPackage>
              <configOptions>
                <interfaceOnly>true</interfaceOnly>
              </configOptions>
            </configuration>
          </execution>
        </executions>
      </plugin>

错误

编辑：使用新版本 - 3.0.27。仍然没有工作

这是yaml文件

我遇到过同样的问题。解决方案是简单地使用 Java 8 来运行它。这让我可以毫无问题地运行这一代
