Question

我希望通过从链接http://www.adam-bien.com/roller/abien/entry/jax_rs_get_swagger_json获取引用来创建swagger.json定义。我刚刚添加了下面提到的插件到我的pom.xml中并执行mvn clean install给我以下显示的错误。请帮帮忙！

<plugin>
    <groupId>com.sebastian-daschner</groupId>
    <artifactId>jaxrs-analyzer-maven-plugin</artifactId>
    <version>0.3</version>
    <executions>
        <execution>
            <goals>
                <goal>analyze-jaxrs</goal>
            </goals>
            <configuration>
                <!-- Available backends, defaults to plaintext -->
                <!-- <backend>plaintext</backend> -->
                <backend>swagger</backend>
            </configuration>
        </execution>
    </executions>
</plugin>

如何解决以下错误？

您似乎使用的是与插件二进制文件不兼容的Java版本。

在您的情况下，插件类文件是使用java 8生成的：

根据JVM，Java SE 8的类文件版本为52.0 规格。由Java SE 8生成的版本52.0类文件编译器不能在早期版本的Java SE中使用。

因此，如果您在项目中使用的是早期版本，那么它将无法正常工作。

jaxrs-analyzer需要Java 8。但是，如果您无法升级项目，仍可以将其用作standalone tool。
