Maven站点在Java 8下失败，当代码具有不完整的Java doc标签

Question

我已将Java 7迁移到Java 8。当我执行mvn install时，构建成功。但是当我执行mvn site时，网站生成会失败，并显示以下错误信息：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.4:site (default-site) on project XXXXXX: Error generating maven-javadoc-plugin:2.8:test-javadoc:

下面是我的pom.xml文件：

我们的测试中有一些Javadoc标签没有文档说明。我尝试实现了这篇文章中提到的解决方案：Maven is not working in Java 8 when Javadoc tags are incomplete。不幸的是，这对我来说并不起作用，或者可能我没有按照正确的方式执行。有人能建议我如何告诉Maven忽略没有文档的Javadoc标签吗？谢谢！

Answer 1

在maven-javadoc-plugin配置中添加以下附加的param标签。

    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-javadoc-plugin</artifactId>
            <configuration>
                <additionalparam>-Xdoclint:none</additionalparam>
            </configuration>
        </plugin>
    </plugins>

参考链接：http://blog.joda.org/2014/02/turning-off-doclint-in-jdk-8-javadoc.html

该链接为 JDK 8 Javadoc 文档检查工具 DocLint 的关闭方法说明。
