考虑一下我用以下方式覆盖了Gradle的clean任务，以便只删除build/目录的某些子目录：
// build.gradle
clean {
delete.clear()
delete.add 'build/kotlin/**'
delete.add 'build/libs/**'
delete.add 'build/tmp/**'
}
这适用于Unices，但在Windows上使用IOException失败：

显然。例外来自java.io.File.getCanonicalPath()电话。该问题可在任何Gradle 5.x版本上重现。
在使用路径时，Gradle是不是应该将斜杠转换为依赖于平台的文件分隔符？
如何以独立于平台的方式重新实现我的build.gradle逻辑？
您不能在提供的文件路径中使用globs（如路径中的**）来删除。 API文档说你可以使用“Project.files(Object...)接受的任何类型的对象”（via），在路径字符串的情况下，“相对于项目目录解释，根据file(Object)”（via）。但是，传递给Project.file(Object)的字符串不支持globs。
在Unix下**是一个完全有效的文件名，所以你的代码在那里工作（虽然没有删除任何东西，除了一些名为**的文件;-)）。在Windows下，不允许使用此类文件名，因此会出现异常。
假设您也可以删除要清理的目录，那么您只需将任务配置更改为以下内容：
clean {
delete.clear()
delete.add 'build/kotlin'
delete.add 'build/libs'
delete.add 'build/tmp'
}
