如何自动将所有javadoc package.html文件转换为package-info.java文件？

我们在我们的项目中使用了很多遗留的package.html文件,我们希望将它们转换为package-info. java 文件.手动执行不是一个选项(文件太多).有没有自动化的好方法？

我们想要转换它们有几个原因：@H_502_3@

>从javadoc规范：这个文件是JDK 5.0中的新文件,并且优于package.html.
>不要在同一个代码库中混合两种类型的文件
>为了避免Intellij / Eclipse构建将这些* .html文件放在我们的类dirs(并且可能在一个发行版二进制jar)中,所以它们的行为就像我们其他正常的html资源.@H_502_3@

解决方法

如果您没有运行Windows,则可能需要更改目录分隔符.此外,转换是一个黑客,但它应该工作.出于好奇,你有多少包这个手册不是一个选择？
