I want to delete all bin and obj folders to force

问题:

I work with multiple projects, and I want to recursively delete all folders with the name 'bin' or 'obj' that way I am sure that all projects will rebuild everything (sometimes it's the only way to force Visual Studio to forget all about previous builds).

Is there a quick way to accomplish this (with a .bat file for example) without having to write a .NET program?

回答1:

This depends on the shell you prefer to use.

If you are using the cmd shell on Windows then the following should work:

FOR /F "tokens=*" %%G IN ('DIR /B /AD /S bin') DO RMDIR /S /Q "%%G"
FOR /F "tokens=*" %%G IN ('DIR /B /AD /S obj') DO RMDIR /S /Q "%%G"

If you are using a bash or zsh type shell (such as git bash or babun on Windows or most Linux / OS X shells) then this is a much nicer, more succinct way to do what you want:

find . -iname "bin" | xargs rm -rf
find . -iname "obj" | xargs rm -rf

and this can be reduced to one line with an OR:

find . -iname "bin" -o -iname "obj" | xargs rm -rf

If you are using Powershell then you can use this:

Get-ChildItem .\ -include bin,obj -Recurse | foreach ($_) { remove-item $_.fullname -Force -Recurse }

as seen in Robert H's answer below - just make sure you give him credit for the powershell answer rather than me if you choose to up-vote anything :)

It would of course be wise to run whatever command you choose somewhere safe first to test it!

回答2:

I found this thread and got bingo. A little more searching turned up this power shell script:

Get-ChildItem .\ -include bin,obj -Recurse | foreach ($_) { remove-item $_.fullname -Force -Recurse }

I thought I'd share, considering that I did not find the answer when I was looking here.

回答3:

This worked for me:

for /d /r . %%d in (bin,obj) do @if exist "%%d" rd /s/q "%%d"

Based on this answer on superuser.com

回答4:

I use to always add a new target on my solutions for achieving this.

<Target Name="clean_folders">
  <RemoveDir Directories=".\ProjectName\bin" />
  <RemoveDir Directories=".\ProjectName\obj" />
  <RemoveDir Directories="$(ProjectVarName)\bin" />
  <RemoveDir Directories="$(ProjectVarName)\obj" />
</Target>

And you can call it from command line

msbuild /t:clean_folders

This can be your batch file.

msbuild /t:clean_folders
PAUSE

回答5:

I wrote a powershell script to do it.

The advantage is that it prints out a summary of deleted folders, and ignored ones if you specified any subfolder hierarchy to be ignored.

回答6:

Nothing worked for me. I needed to delete all files in bin and obj folders for debug and release. My solution:

1.Right click project, unload, right click again edit, go to bottom

2.Insert

<Target Name="DeleteBinObjFolders" BeforeTargets="Clean">
  <RemoveDir Directories="..\..\Publish" />
  <RemoveDir Directories=".\bin" />
  <RemoveDir Directories="$(BaseIntermediateOutputPath)" />
</Target>

3. Save, reload project, right click clean and presto.

回答7:

Something like that should do it in a pretty elegant way, after clean target:

<Target Name="RemoveObjAndBin" AfterTargets="Clean">
    <RemoveDir Directories="$(BaseIntermediateOutputPath)" />
    <RemoveDir Directories="$(TargetDir)" />
</Target>

回答8:

To delete bin and obj before build add to project file:

<Target Name="BeforeBuild">
    <!-- Remove obj folder -->
    <RemoveDir Directories="$(BaseIntermediateOutputPath)" />
    <!-- Remove bin folder -->
    <RemoveDir Directories="$(BaseOutputPath)" />
</Target>

Here is article: How to remove bin and/or obj folder before the build or deploy

回答9:

Have a look at the CleanProject, it will delete bin folders, obj folders, TestResults folders and Resharper folders. The source code is also available.

回答10:

Very similar to Steve's PowerShell scripts. I just added TestResults and packages to it as it is needed for most of the projects.

Get-ChildItem .\ -include bin,obj,packages,TestResults -Recurse | foreach ($_) { remove-item $_.fullname -Force -Recurse }

回答11:

Is 'clean' not good enough? Note that you can call msbuild with /t:clean from the command-line.

回答12:

from Using Windows PowerShell to remove obj, bin and ReSharper folders

very similar to Robert H answer with shorter syntax

1. run powershell
2. cd(change dir) to root of your project folder

3. paste and run below script

   dir .\ -include bin,obj,resharper* -recurse | foreach($) { rd $_.fullname –Recurse –Force}

回答13:

Here is the answer I gave to a similar question, Simple, easy, works pretty good and does not require anything else than what you already have with Visual Studio.

As others have responded already Clean will remove all artifacts that are generated by the build. But it will leave behind everything else.

If you have some customizations in your MSBuild project this could spell trouble and leave behind stuff you would think it should have deleted.

You can circumvent this problem with a simple change to your .*proj by adding this somewhere near the end :

<Target Name="SpicNSpan"
        AfterTargets="Clean">
    <RemoveDir Directories="$(OUTDIR)"/>
</Target>

Which will remove everything in your bin folder of the current platform/configuration.

回答14:

On our build server, we explicitly delete the bin and obj directories, via nant scripts.

Each project build script is responsible for it's output/temp directories. Works nicely that way. So when we change a project and add a new one, we base the script off a working script, and you notice the delete stage and take care of it.

If you doing it on you logic development machine, I'd stick to clean via Visual Studio as others have mentioned.

回答15:

http://vsclean.codeplex.com/

Command line tool that finds Visual Studio solutions and runs the Clean command on them. This lets you clean up the /bin/* directories of all those old projects you have lying around on your harddrive

回答16:

You could actually take the PS suggestion a little further and create a vbs file in the project directory like this:

Option Explicit
Dim oShell, appCmd
Set oShell  = CreateObject("WScript.Shell")
appCmd      = "powershell -noexit Get-ChildItem .\ -include bin,obj -Recurse | foreach ($_) { remove-item $_.fullname -Force -Recurse -WhatIf }"
oShell.Run appCmd, 4, false

For safety, I have included -WhatIf parameter, so remove it if you are satisfied with the list on the first run.

回答17:

I actually hate obj files littering the source trees. I usually setup projects so that they output obj files outside source tree. For C# projects I usually use

 <IntermediateOutputPath>..\..\obj\$(AssemblyName)\$(Configuration)\</IntermediateOutputPath>

For C++ projects

 IntermediateDirectory="..\..\obj\$(ProjectName)\$(ConfigurationName)"

回答18:

We have a large .SLN files with many project files. I started the policy of having a "ViewLocal" directory where all non-sourcecontrolled files are located. Inside that directory is an 'Inter' and an 'Out' directory. For the intermediate files, and the output files, respectively.

This obviously makes it easy to just go to your 'viewlocal' directory and do a simple delete, to get rid of everything.

Before you spent time figuring out a way to work around this with scripts, you might think about setting up something similar.

I won't lie though, maintaining such a setup in a large organization has proved....interesting. Especially when you use technologies such as QT that like to process files and create non-sourcecontrolled source files. But that is a whole OTHER story!

回答19:

Considering the PS1 file is present in the currentFolder (the folder within which you need to delete bin and obj folders)

$currentPath = $MyInvocation.MyCommand.Path
$currentFolder = Split-Path $currentPath

Get-ChildItem $currentFolder -include bin,obj -Recurse | foreach ($_) { remove-item $_.fullname -Force -Recurse }

回答20:

This is my batch file that I use for deleting all BIN and OBJ folders recursively.

1. Create an empty file and name it DeleteBinObjFolders.bat
2. Copy-paste code the below code into the DeleteBinObjFolders.bat
3. Move the DeleteBinObjFolders.bat file in the same folder with your solution (*.sln) file.

@echo off
@echo Deleting all BIN and OBJ folders...
for /d /r . %%d in (bin,obj) do @if exist "%%d" rd /s/q "%%d"
@echo BIN and OBJ folders successfully deleted :) Close the window.
pause > nul

回答21:

For the solution in batch. I am using the following command:

FOR /D /R %%G in (obj,bin) DO @IF EXIST %%G IF %%~aG geq d RMDIR /S /Q "%%G"

---

The reason not using DIR /S /AD /B xxx
1. DIR /S /AD /B obj will return empty list (at least on my Windows10)
2. DIR /S /AD /B *obj will contain the result which is not expected (tobj folder)

回答22:

I think you can right click to your solution/project and click "Clean" button.

As far as I remember it was working like that. I don't have my VS.NET with me now so can't test it.
