MSB3073 Error Is too weird

General JUCE discussion
1

Hey everyone, I’m very new to Juce and audio dev.
Ive solved many problems but this one is far beyond my comprehension

I keep getting this error when compiling and I dont know what to look for :

MSB3073
The command "copy /Y “C:\Users\User\Desktop\PROJETS JUCE\LITTLE CAT\Builds\VisualStudio2022\x64\Release\VST3\LITTLE CAT.dll” “C:\Users\User\Desktop\PROJETS JUCE\LITTLE CAT\Builds\VisualStudio2022\x64\Release\VST3\LITTLE CAT.vst3\Contents\x86_64-win\LITTLE CAT.vst3”

Output Error

C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Microsoft\VC\v170\Microsoft.CppCommon.targets(166,5): error MSB3073: The command “copy /Y “C:\Users\User\Desktop\PROJETS JUCE\LITTLE CAT\Builds\VisualStudio2022\x64\Release\VST3\LITTLE CAT.dll” “C:\Users\User\Desktop\PROJETS JUCE\LITTLE CAT\Builds\VisualStudio2022\x64\Release\VST3\LITTLE CAT.vst3\Contents\x86_64-win\LITTLE CAT.vst3”

The error message indicates that the tool is returning an exit code of -107374181 which typically suggests a general Windows error?

I tried to :
Run visual studio with admin right, failed
Verify the permission to write in the output folder, failed
Clean solution, Rebuild, failed
Juce + Visual are up to date, failed
Try to build as release and debug, failed both

Does someone know what is happening? Or what should I try next? :skull:

EDIT : I tried some stuffs that was posted in this topic : Suddenly can't build vst3 in Windows...|Error|MSB3073|The command copy /Y
But it doesnt seem to work for me

@AddisonDeSaulenet unfortunately the output when there is an error in the post build script isn’t very helpful.

The most common issue is that there is a problem with loading or unloading your VST3 plugin. The post build script actually loads your plugin straight after you build, this is so that it can generate a file called “moduleinfo.json”.

In the topic you linked, did you try to follow the steps outlined by @cblessing?

Suddenly can't build vst3 in Windows...|Error|MSB3073|The command copy /Y - #16 by cblessing)?

If however you think it might be a problem with copying the plugin you can try disabling the plugin copy step in the Projucer to see if the error goes away?
