How to move directories using jdk7

由 牧云@^-^@ 提交于 2019-12-12 11:26:21
问题 Using jdk7 , I am trying to use the java.nio.file.Files class to move an empty directory, let's say Bar , into another empty directory, let's say Foo Path source = Paths.get("Bar"); Path target = Paths.get("Foo"); try { Files.move( source, target, StandardCopyOption.REPLACE_EXISTING); } catch (IOException e) { e.printStackTrace(); } After executing that code snippet, I expected that the Bar directory would be in the Foo directory ( ...\Foo\Bar ). Instead it is not. And here's the kicker, it's

Order of traversal in Files.walkFileTree

由 五迷三道 提交于 2019-12-06 18:28:08
问题 What is the order in which Files.walkFileTree visits files/directories at the same level? It doesn't appear to visit them in order of size, last modified time or name. I couldn't find anything in the API documentation either. Perhaps the preVisitDirectory method can be used to specify the order of visit but what is default behaviour ? 回答1: The order in which the subdirectories are read is not defined as per this comment in the Java Tutorial: A file tree is walked depth first, but you cannot

java.nio.file: Where is the Path interface actually implemented?

由 百般思念 提交于 2019-12-05 14:05:14
问题 Recently I was doing some coding using the java.nio.file package introduced in Java 7 and saw an example using Path like this: Path path = Paths.get("C:\\Users"); Given that Path is an interface I was confused on how you could have a reference to it, however after some research I found out that a reference to an interface is allowed but it must point to a class that implements the interface. Looking on from this I looked at the Paths class and saw that it didn't implement Path. Looking at the

Issue with Jenkins pipeline and java.nio.file.* methods

由 独自空忆成欢 提交于 2019-12-05 07:08:02
I am trying to use methods from java.nio.file.* to perform some basic file operations in a Jenkins pipeline. Regardless of the node block in which the code exists, the code executes on the master node. In the pipeline, I have verified that the various node blocks are correct--they uniquely identify specific nodes. However, pathExists (and other code that moves, copies, or deletes files) always executes on the master node. Any ideas what's happening or how to fix it? import java.nio.file.* String slavePath = 'C:\\Something\\only\\on\\slave\\node' String masterPath = 'D:\\Something\\only\\on\
