My Gradle project depends on commons-io 2.4, but Gradle puts $GRADLE_HOME/commons-io-1.4.jar into the classpath, causing failures

问题 I've been iterating on features in my first Gradle plugin. I determined early on that I needed commons-io, so I added a dependency on commons-io 2.4, being the latest version. This has been going well for a while, with the build working from the command line, and no errors in Eclipse. I just started trying to integrate some code that uses "FileUtils.write(File,String)". I didn't need that method before. I got everything un-redded in Eclipse, and then I tried a command line build. This failed

Why can't I read from /proc in Java using Commons IO FileUtils, but can do so using a plain FileInputStream?

问题 I had a problem with reading /proc/%d/stat files using my Java method copyFiles() (source code below). I have found workaround using similar readProc() method. Now I am wondering what was the problem. Output files were created, but each file had 0 bytes (in /proc/ all files are 0 bytes because it is not standard filesystem). FileUtils is from the Apache Commons IO library. I've tried to do the same using java.nio - again, IOException is being thrown that attributes are wrong for each file. I

Progress bar with Apache FileUtils.copyDirectory(…)

由 こ雲淡風輕ζ 提交于 2019-12-10 15:53:50
问题 Does anyone know any way of implementing progress bar for Apache's FileUtils.copyDirectory(File src, File dst) ? I don't see anything helpful in JavaDocs and API. Seems like a common use case in dealing with batch disk operations, so I'm not sure if I miss something obvious. 回答1: I guess you will have to do that yourself. I see this immediate solution: Find all files you are about to copy and count the number or total file size first (depending on what your progress bar should measure) Copy

问题 I want to delete all files inside ABC directory. When I tried with FileUtils.deleteDirectory(new File("C:/test/ABC/")); it also deletes folder ABC.

This will also recursively deletes all sub-folders and files under them. Docs: org.apache.commons.io.FileUtils.cleanDirectory 回答2: Do you mean like? for(File file: dir
