Build succeeds, but publish fails

问题:

Up until two days ago, I was able to use Visual Studio 2010's "Publish Web" option by right clicking on my project and clicking the publish button on the context menu. Now when I try to do the same thing, I get the following output:

------ Build started: Project: ELMS, Configuration: Debug Any CPU ------
Build started 8/1/2011 3:08:03 PM.
GenerateTargetFrameworkMonikerAttribute:
Skipping target "GenerateTargetFrameworkMonikerAttribute" because all output files are
up-to-date with respect to the input files.
_CopyOutOfDateSourceItemsToOutputDirectoryAlways:

  "bin\lib\Newtonsoft.Json.Net35.dll".
CopyFilesToOutputDirectory:
  LMS -> C:\SVN\TrakNet\trunk\MTS\bin\LMS.dll

Build succeeded.

Object reference not set to an instance of an object.
========== Build: 1 succeeded or up-to-date, 0 failed, 0 skipped ==========
========== Publish: 0 succeeded, 1 failed, 0 skipped ==========

This is while attempting to publish to localhost (for debugging purposes)

Here are the settings of the publish profile that I'm using:

Publish Method: Web Deploy
Service URL: localhost
Site/application: default web site/ELMS
[x] Mark as IIS application on destination
[x] Leave extra files on destination (do not delete)

I have already attempted:

- Cleaning/rebuilding the project
- Deleting the bin folder of the project
- Running reg_iis.exe -i
- Reinstalling VS2010

but nothing I've changed has fixed the error.

Any insight into what might be causing the issue would be greatly appreciated :)

EDIT:

The problem actually resolved itself as of my last reboot. I must have rebooted 6-7 times since the problem first manifested itself, but this time no Object Reference message. Here's the log from the build/publish now:

Like I said: No idea what changed. I had been manually moving the DLLs into the website's virtual directory, then just for kicks I tried publishing this morning, and everything worked out fine.

回答1:

In my experience this can happen when files are added/removed from different branches of your source control and an imperfect merge causes the project file structure and the actual file structure to diverge.

This could be one of several options:

• A file was deleted but the project still references it. Will fail to compile, will fail to publish.
• A file was added but is not referenced by the project. May compile, depends whether the class/methods are referenced elsewhere in the project/solution. If compiles, will publish.
• A file was added, but the project merge caused it to appear more than once in the project listing. Will compile, will fail to publish.

The solution is to look at the source control logs and trying to identify the bad merge to the project file for the above issues, then fixing the project file accordingly.

回答2:

Me also faced same issue, I just removed yellow marked file from visual studio project solution & it worked fine for me.

回答3:

Exclude the obj folder from project and publish. This worked for me

回答4:

I had this issue recently publishing to Azure. I ended up deleting all the files in the bin folder( deleted all files WITHIN visual studio solution explorer under bin folder, but leave the bin folder itself empty) , and rebuilding the project. This seemed to make visual studio happy and azure publish worked. hope this helps

回答5:

This worked for me: Manually delete the obj folder, rebuild, then publish. Somehow some permission in the obj folder got stuck, and deleting/recreating the folder cleared the error.

回答6:

I removed bin & obj folder and also the content of the inetpub/wwwroot/myapp and problem solve

回答7:

open projectname.csproj file in notepad and remove obj\debug\project name.csprojResolveAsseblyReference.cache line

回答8:

I recently faced the same issue. And I actually traced it by searching the file which was missing.

Reason for the error : In visual studio I had included the file and later on deleted it from file system.(but not from visual studio). VS had still had the reference to that file. So once I deleted the reference from VS I was able to publish successfully !

回答9:

nothings work for me. deleting obj and bin file-clean-changing webservice name-shorten webservice name.

But at all,

+Expand your Reference.svcmap from visual studio.

+Update reference.

+And delete yellow warning datasources.

works for me

回答10:

I ran into a similar problem when I manually copied a folder into a project (in my case ckeditor). It built fine and ran locally with no issues. However, when publishing the folder was ignored. It turns out I had to create the empty folder 1st and then copy in the folder contents. Visual Studio needs to know the item was created it appears, because after that it was recognized upon publishing.

回答11:

This issue may come because of move project from one solution to another solution or moving to another source control.

Simple way to resolve this issue:

1. Take the current project backup and remove you current project from solution.

2. Add new project to your solution and include your files from backup and rebuild your project and done.

回答12:

The cause of it is the transfer your project from different environment. To solve it, delete "obj" folder from your project directory as well as from solution explorer by right click on "obj" folder.

After that build your project and publish it. It will work normally.

回答13:

I resolved this by removing the file "packages.config" from my Project, which was flagged as missing. After that, Publish worked just fine.

回答14:

I had to manually copy and paste the missing files VS was asking for into the BIN folder. .pbd, .xml Sometimes they don't copy over.

回答15:

Just rename Packages folder of Nugets. Visual Studio would automatically get required packages and build would get successful and Publish would work too.

回答16:

In case this helps anyone, for my MVC project in VS 2015 it was this file: File System.pubxml.user In the publish profile directory, including it caused compilation errors but deleting it enabled it to publish!

回答17:

I had to delete the publish profile, commit, and then recreate the publish profile from scratch.

回答18:

I deleted all the existing publish profiles in visual studio -> solution explorer -> My Project Node -> Properties -> Publish Profiles The same can be done by right clicking Project in solution explorer -> Publish -> Profile tab -> Manage Profiles -> Remove all profiles Now download the relevant profile from Azure or choose from your directory if it's already save on your machine and choose it. Then clean and rebuild the project. Make sure you've chosen the project is built in Release mode and you've also chosen "Release" Publish -> Settings -> Configuration Now Publish, it worked for me.
