Visual Studio 2015 hybrid app - getting “EPERM, operation not permitted”

Question

I having kind of absurd situation and I will glad to hear how exactly you guys handling it:

I have a Hybrid App project, Visual Studio 2015 Cordova Tools. Inside it, under "res" folder I have app resources. The whole project, including resources, is under source control (TFS).

During build, resource files get copied into "..\platforms\android\res" folder.

First time, while the folder empty it succeeded - the files get copied as-is (e.g. read-only, since they are under source control). After that, during next build, it trying to overwrite these read-only files and failed, as expected - displaying that informative error: "EPERM, operation not permitted 'resource full path'.

I don't get it. Resources must be under source control, so I guess 99.99% of developers would get the same problem as I do.

What do I miss?

Thanks

Answer 1

I thought I'd chime in here with what I've done. The problem is that "platforms" is not checked into source, but it is still being marked as Read-Only. So the first time it builds it works and subsequent builds fail unless you do a clean solution.

What I've done is I remove the Read-Only flag before build.

Right click project, Unload Project. Right click, edit project file. At the top, add a target named BeforeBuild for example:

<Project ToolsVersion="14.0" DefaultTargets="BeforeBuild;Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

Then at the bottom of the file where the targets go you can add a target like this:

<Target Name="BeforeBuild">
    <Exec Command="attrib -R &quot;$(SolutionDir)YourProjectName\platforms\*.*&quot; /S" IgnoreExitCode="true" />
</Target>

Check if the folder is Read Only, if it is - uncheck the "Read Only" property on the folder and select "Apply changes to this folder, subfolders and files"

I get the same exception when I use TFS with Cordova.

When I'm committing the folder become Read Only, that's a very annoying bug...

Answer 3

For me, the directory that the error message pointed to was just plain missing. Same IDE, same type of app.

It was looking for \GitHub...\myProjectName\platforms\windows\www

I manually added the dir (www) back in and the project ran fine. The IDE deletes that dir at the beginning of the build then throws the EPERM exception. Sure looks like a bug to me.
