Can I ask debugging questions here? I have an issue with gradle not being able to run "gradle clean build". This is the first time I am using gradle and I ran a command that I do not remember to fuse it with an already existing github project (only containing a basic .java file with nothing important in it yet). I made a library project. I am getting:

I tried pausing my onedrive sync, running "gradle --stop" gradle --status tells me no more daemons are running although one becomes idle when I try to clean. I have nothing open but VScode and firefox. I have no files open but it cant delete the build directory. Edit: I just tried it again and it works now but I didnt do anything different. Does anyone have any idea what happened?

Try to exclude

build

folders of your project from onedrive. I'm curious what is the point to sync github projects to onedrive?

Can I ask debugging questions here?

Sure, but please keep the original message small and put bigger snippets like your output to the thread of the initial message, that way the channel is much easier to follow, especially on mobile devices. For sharing build outputs or errors, most often a build

--scan

URL is the easiest and best way, as it also includes much more information that might help people trying to help you. 😉 As you say it is your first time you try using Gradle, let's start with a general advice. 🙂 Gradle is not Maven, so don't always run with

clean

. With most Maven builds it is better to always run with

clean

to get reliable builds or even correct results. With Gradle this is just a big waste of time, as you effectively disable what Gradle is best in, i.e. avoiding unnecessary work. If you need to run a Gradle build always with

clean

for some reason, then there is either a bug in Gradle, in one of the plugins you use, or in your build script, and you should try to fix that instead of using

clean

to save a tremendous amount of time. Another important point, never use the command

gradle

. I do not even ever have any Gradle version installed locally. Each and every project should contain the 4 Gradle wrapper files, and you should always use the Gradle wrapper to run a build, as it defines exactly which version of Gradle should be used to run a given build for which the build was designed and is known working with. Imho any project not containing the 4 wrapper files has a build bug. (or is one of those rare cases where some rules disallow adding a JAR to the project VCS or similar) Regarding the actual error you got, well, that is the joy of using Windows. If a file is locked by some process, another process cannot update or delete it. What caused this, noone here can tell you. My recommendation would actually be, switch to Linux. 😄 But assuming that this is not an option for you, there are tools like

handle

or "Process Explorer" in which you can search for the process having an open handle to a given file, so these can tell you exactly which process is holding the locks that prevent Gradle from deleting the files.
