问题：

Maven javadoc插件-包不存在

魏浩广
2023-03-14

我对maven javadoc插件有点问题。实际上，我试图创建一个javadoc，它只包含我的两个java类。但是当尝试构建时，我总是会得到一个错误列表，例如“包不存在”错误，但这个包是我在Eclipse中自己创建的包。

仅供参考：我使用Java8，Eclipse Mars，m2eclipse。我使用m2eclipse的默认“Maven install”命令构建。

这是我的pom。xml文件

试试这个：

<configuration>
  <sourceFileIncludes>
    <include>**/DataHandler.java</include>
    <include>**/ChestBackpackAPI.java</include>
  </sourceFileIncludes>
</configuration>

Sourcepath必须指向源的根文件夹，它们不得包含包信息。源文件包含必须包含包信息。
