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

导读: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: 从javadoc规范:这个文件是JDK 5.0中的新文件,并且优于package.html

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: >从javadoc规范:这个文件是JDK 5.0中的新文件,并且优于package.html. 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?public class Converter {
