It is causing possibly because that jar is not added to your project build path. Follow this steps:
这可能是因为该 jar 未添加到您的项目构建路径中。请按照以下步骤操作：
Right click on project(in the package explorer)
-> Buid Path
-> Configure Build Path
-> Java Build Path
-> Libraries tab
-> Add JARs button
Then locate the folder where the jar resides. You can filter your search by typing *.jarin the search field. And then click ok.
然后找到jar所在的文件夹。您可以通过*.jar在搜索字段中输入来过滤搜索。然后点击确定。

I downloaded the xdoclet-lib-1.2.3.zip file from: http://sourceforge.net/projects/xdoclet/files/xdoclet/1.2.3/unziped it to its folder name, xdoclet-1.2.3, and then from the Eclipse (I was using 4.5) preferences JavaEE -> XDoclet tab selected the Version 1.2.3 and then the Browse button to the xdoclet-1.2.3 folder. Apply and OK and Eclipse error goes away.
我从以下位置下载了 xdoclet-lib-1.2.3.zip 文件：http: //sourceforge.net/projects/xdoclet/files/xdoclet/1.2.3/将其解压缩 到其文件夹名称 xdoclet-1.2.3，然后从 Eclipse（我使用的是 4.5）首选项 JavaEE -> XDoclet 选项卡选择版本 1.2.3，然后浏览按钮到 xdoclet-1.2.3 文件夹。应用并确定，Eclipse 错误消失。
Saying all that, I suspect you don't really need it unless you know that you are using xdoclet. If that's the case and it was intentionally left out then the error message should be fixed in Eclipse. I only went around fixing it because of the message.
综上所述，我怀疑您并不真正需要它，除非您知道您正在使用 xdoclet。如果是这种情况并且有意将其排除在外，则应在 Eclipse 中修复错误消息。我只是因为消息而四处修理它。

If have maven version of the project, can also try by updating the project. I also had this XDoclet. 1.2.1.jar complaint, which got resolved once I update the project.
如果有maven版本的项目，也可以通过更新项目来尝试。我也有这个 XDoclet。1.2.1.jar 投诉，在我更新项目后得到解决。
Right Click Project > Maven > Update Project ... > Check the projects > OK.
右键单击项目 > Maven > 更新项目 ... > 检查项目 > 确定。
