maven Javadoc'无法找到默认设置程序'并失败

Question

无法解析mojoorg.apache.maven.plugins的配置：maven-javadoc-plugin： 2.10.3： javadoc for参数#：无法在类org.apache.maven.plugin.javadoc.options.Group中找到默认的setter。我使用的命令是根目录下的mvn javadoc： javadoc，其中pom位于。

我根本没有配置组，也没有任何特殊的配置。无论我完全忽略pom中的插件，将其添加到报告中，还是添加为构建插件，都会遇到同样的错误。我也尝试过添加空组，虽然消息有所改变，但它仍然会出现。

我遇到了这个SO问题，但是a.我没有TestNG依赖关系，b.我没有使用命令行参数，c.它从未解决。

这是一个硒项目，所以我想可能有类似的东西，但我不能弄清楚。有什么想法吗？我已经在下面包含了maven调试堆栈跟踪。

该错误消息表示配置程序无法将字符串转换为实例。而不是像

<groups>
  <group>com.example</group>
  ...
</groups>

尝试重新工作您的组，使其看起来像使用示例：

<groups>
  <group>
    <title>Core Packages</title>
    <!-- To includes java.lang, java.lang.ref,
    java.lang.reflect and only java.util
    (i.e. not java.util.jar) -->
    <packages>java.lang*:java.util</packages>
  </group>
  <group>
    <title>Extension Packages</title>
     <!-- To include javax.accessibility,
    javax.crypto, ... (among others) -->
    <packages>javax.*</packages>
  </group>
</groups>
