## 问题和原因

出现上面错误信息的原因是在Java 代码编译的时候我们使用了一些在 JDK-17 中才有的属性。

但是生成的 Doc 文档却是使用的是 JDK 11。

我们需要做的就是在 maven-javadoc-plugin 插件中指定 JDK 的版本。

对插件添加下面的内容：

```xml
                <configuration>
                    <release>${java.version}</release>
                    <encoding>UTF-8</encoding>
                </configuration>

```

因为我们上面使用了全局配置变量，所以这里用的是变量类型，你也可以在这里直接使用数字 17。

配置参数：

```xml
<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-javadoc-plugin</artifactId>
                <version>${maven-javadoc-plugin.version}</version>
                <configuration>
                    <release>${java.version}</release>
                    <encoding>UTF-8</encoding>
                </configuration>
                <executions>
                    <execution>
                        <id>attach-javadocs</id>
                        <goals>
                            <goal>jar</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

```

把上图中的配置参数添加到 POM 文件中。
