java.lang.TypeNotPresentException : Type com. sebastian_daschner.jaxrs_analyzer.maven.JAXRSAnalyzerMojo 不存在

Question

我希望通过引用链接 http://www.adam-bien.com/roller/abien/entry/jax_rs_get_swagger_json 来创建 swagger.json 定义。我将刚刚添加的下面提到的插件添加到我的 pom.xml 中并执行 mvn clean install 给出以下显示的错误。请帮忙，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？

您使用的 java 版本似乎与插件二进制文件不兼容。

在您的例子中，插件类文件是使用 java 8 生成的:

The class file version for Java SE 8 is 52.0 as per the JVM Specification. Version 52.0 class files produced by a Java SE 8 compiler cannot be used in earlier releases of Java SE.

因此，如果您在项目中使用早期版本，它将无法工作。

jaxrs-analysisr 需要 Java 8。但是，您仍然可以将其用作 standalone tool如果您无法升级您的项目。
