我正在使用Netbeans，也尝试了命令提示符。在这两种情况下，我得到相同的错误。
当我尝试生成我的JavaDocs时，我得到一个非法参数异常。我做了研究，建议使用Clear out your Classpath Bug Ticket
有人可以指导我，我正在清除什么，以及我将如何在Windows机器上做。
用JDK 1.6，也用JDK 1.7试验
Netbeans输出

C:UsersSomeProjectnbprojectbuild-impl.xml:1228: Javadoc returned 1
答案很简单
1)打开命令提示符2)输入以下命令清除类路径
set classpath=
3)在相同的命令提示窗口中运行Javadoc命令
javadoc -d <path to save docs to> -sourcepath <location of code/files> <package name>
