Build fails first time after layout file changed and saved #2427

rihadavid · 2018-11-11T20:02:29Z

Sometimes when I want to build and debug my project, it fails without any error in Output windows or in log files. Next time it works without issues.

This is how my output window looks:

1>------ Build started: Project: MyApp.Android, Configuration: Debug Any CPU ------
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
========== Deploy: 0 succeeded, 0 failed, 0 skipped ==========

And that's it. Note that I have it on a diagnostic verbosity.

Please let me know what can I do to get you more info, it's happening quite often, but conditions are unknown.

rihadavid · 2018-11-14T14:58:06Z

I have just found exact steps for this issue:

Create the sample single view android project
Open content_main.axml and change anything in the file - for example, change "Hello world!" to "Hello Xamarin!" in the TextView
Save all files
Build
The build fails, without any error. Build again and it succeeds.

Note that if you skip the step 3 and let the files save automatically by building, the issue is not present and it builds successfully.

rihadavid · 2018-11-21T06:21:16Z

Anybody could look at this? :) Maybe @jonathanpeppers or @garuma ? And also the other issue #2425 I reported 10 days ago. These two issues are getting quite annoying 🤕 Thanks!

rihadavid · 2018-11-26T11:30:07Z

Now I am not sure whether we should report Xamarin bugs in Visual Studio reporting system where it takes forever to get a response to a reported issue or github where, well, it takes the same.
Maybe I should start awaiting an email that my issues were closed because of inactivity 😄

jonathanpeppers · 2018-11-26T14:28:15Z

@rihadavid, sorry I have been out of the office for two weeks (work trip + Thanksgiving).

I tried your steps above with VS 15.9.1 and it worked for me. Have you tried updating to 15.9?

If you are still seeing the issue, can you post the error message you are getting? Are the logs always blank? (try this setting)

rihadavid · 2018-11-26T15:31:20Z

Thanks for the reply!
It's still happening in 15.9.2 and I was using the diagnostic output from the start.
Now in 15.9.2, it gives this output:

jonathanpeppers · 2018-11-26T16:03:26Z

@rihadavid it looks like your logging is set to minimal.

The top of mine looks like:

You should also see an error message somewhere? In the error pad?

rihadavid · 2018-11-26T16:08:35Z

It looks exactly like yours when it builds without the error (second time, or without saving the edited file).

Yes, I should see the error, but I don't, that's the thing

jonathanpeppers · 2018-11-26T16:12:28Z

Can you save the file, then build command line?

# NOTE: Your MSBuild is probably at C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\15.0\Bin\MSBuild.exe
msbuild YourSolution.sln /bl

This will put a msbuild.binlog file in the current directory you can zip and upload here.

You might also get a better error message.

rihadavid · 2018-11-26T16:19:52Z

When using the command line, the build always succeeds. Tried multiple times, with the exact steps - happening in VS, not happening in cmd.
Successful msbuild.binlog: msbuild.zip

jonathanpeppers · 2018-11-26T16:33:29Z

@joj have you seen something like this?

joj · 2018-11-26T17:17:46Z

@jonathanpeppers I haven't. My guess is that there's a file getting locked by msbuild still running on VS, which doesn't happen in command line. I may be completely wrong, though.

joj · 2018-11-26T17:19:10Z

@rihadavid sorry for the time it took to answer on developer community. We're actively improving that now so timing should be much faster.

jonathanpeppers · 2019-02-05T15:37:31Z

@joj any updates? @kzu mentioned that you guys were adding some locking to prevent two builds happening at once?

(I assume it must be rare, because I haven't seen this happen myself)

joj · 2019-02-05T15:40:19Z

I need to find the DevCom item. I'm on something right now, but I will asap.

kzu · 2019-02-07T01:12:19Z

@jonathanpeppers at least on the XVS side of the house, we don't manually trigger any builds for .axml updates, so if something happens as a side effect of that via a %(Generator), then that's all just MSBuild. Not sure if @garuma is doing something on save there which could also trigger this behavior.

SSELLIOTTHOME · 2019-03-01T16:32:11Z

I have replicated this very same problem. It happens on large non trivial projects, and only after upgrading Visual Studio 2017 from quite an early one. Whilst it is not a show stopper, it is not great.

Steven

pjcollins · 2019-06-20T19:20:27Z

I don't think we've ever managed to come up with a consistent reproduction for this. I am going to close it, please feel free to reopen if there are any consistent steps that can be used to help narrow down what's going wrong here.

rihadavid · 2019-06-20T19:27:17Z

@pjcollins for me, it's still happening every time in VS 2019 16.1.2 using the exact steps written in the second comment

pjcollins · 2019-06-20T22:00:36Z

Sorry for the abrupt resolution, I took another look at this with VS 2019 16.1 and I am seeing similar behavior.

Steps (as described above):

Create a new Single View Android App.
Wait for initial design time build to complete, and intellisense to show up.
Open Resources -> layout -> content_main.axml.
Change "Hello World" text to anything else.
Press CTRL+S to save.
Press F5.

I see a build failure reported in the build output, and sometimes the build partially continues, but ultimately it never completes - https://gist.github.com/pjcollins/0dca5a483a9d30873578a972a6001b49.

xa2427.zip

Edit: after some more investigation, it appears that there might be some interference caused by Live Code Analysis:

rob313663 · 2019-06-20T22:55:21Z

I'm only writing here to get updates on the issue. Reported the same thing through Help/Send Feedback/Report a Problem in VS yesterday. @pjcollins you can close the report I made if you like.

rihadavid · 2019-08-13T17:21:48Z

ATTENTION PLEASE
9 months later, still not fixed. And it got much worse:

The original steps, updated with the bold text:

Create the sample single view android project
Open content_main.axml and change anything in the file - for example, change "Hello world!" to "Hello Xamarin!" in the TextView
Save all files
Build
The build fails, ~~without any error. Build again and it succeeds.~~ with tons of unrelated, misleading errors. Also your Android designer window goes black.
Building again does not help now, you need to clean and rebuild.

I also have many other new frustrating errors with the latest 16.2.1, but I am not really sure if reporting them is worth the effort, considering it will take (hopefully) about a year to get a fix 🤔

jonathanpeppers · 2019-08-13T17:25:30Z

@rihadavid the original issue here taht @pjcollins and I could reproduce was related to the Code Analyzer in Visual Studio that we don't have much control over....

Could you file a new issue for what you see with latest 16.2, it is a different issue, correct?

rihadavid · 2019-08-13T17:26:31Z

@jonathanpeppers it's the exactly same issue, just the symptoms got worse

jonathanpeppers · 2019-08-13T17:28:37Z

@rihadavid but if you actually have a build log, then it is a different issue?

You said it has misleading errors. Before we were getting empty build logs and no error information, such as:

1>------ Build started: Project: MyApp.Android, Configuration: Debug Any CPU ------
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
========== Deploy: 0 succeeded, 0 failed, 0 skipped ==========

rob313663 · 2019-08-13T17:34:16Z

It is so easy to reproduce. Why the discussion? If you are not able to reproduce, please say so, I am happy to let you remote control my pc and investigate if you like.

These steps just worked for me: #2427 (comment)

Can someone share diagnostic build logs of what you're seeing?

https://docs.microsoft.com/en-us/xamarin/android/troubleshooting/troubleshooting#diagnostic-msbuild-output

rihadavid · 2019-08-13T17:39:16Z

@jonathanpeppers turns out it's even more tricky:

Create the sample single view android project
Open content_main.axml and change anything in the file - for example, change "Hello world!" to "Hello Xamarin!" in the TextView
Save all files
Build
The build fails, without any error. ~~Build again and it succeeds.~~
Build again and it sometimes fails, again without any error, and sometimes succeeds.
OR, INSTEAD OF THE STEP 6, edit the axml file again and this time, do not save it but build it unsaved - then the build fails with tons of unrelated, misleading errors (see below). Also your Android designer window goes black. Now the only thing that helps is cleaning and rebuilding.

This is a completely different issue than what we were seeing with the code analyzer.

I am not sure what is different with my PC, but I can't get it to fail like this. Can you include the full log?

jonathanpeppers · 2019-08-13T17:43:45Z

So a theory... I think I reproduced it when I rename C:\Program Files (x86)\Android\android-sdk\ndk-bundle to something else where Xamarin.Android can't find it.

If you install the Android NDK, does that help?

rihadavid · 2019-08-13T18:16:04Z

Ok, so it seems that those are actually two issues, not one. I created a report for the other one: #3494
Unfortunatelly, installing NDK (and restarting VS) did not help with any of them.

So, to make it clear, for this issue we can stick with the steps in the second comment, it's still happening the same, except that building again (in the last step) now doesn't always work.

rihadavid · 2019-10-01T21:18:47Z

@jonathanpeppers still happening in VS 16.3.0 .. the only way out of this is to try build (or clean) again and again and again and again.. about 10th attempt usually works.

jonathanpeppers · 2019-10-01T21:33:42Z

@rihadavid so is this still the issue with the code analyzer or #3494? I just retested what I thought we fixed for #3494 and it seems to be fixed for me with 16.3.2. It was these steps: #3494 (comment)

We have a similar problem we are tracking here, but we don't have clear steps to repro this: #3702

rihadavid · 2019-10-01T21:45:22Z

#3494 seems to be fixed, but this one, using the steps in the second comment is still happening. Without any logs, just failing.

I think it will not be related to #3702, as that one is having error logs, this one does not.

jonathanpeppers · 2019-10-01T21:51:13Z

Since, I can't repro it, do you have the same options as me here?

Could I have unchecked the Enable full solution analysis box, and that fixed it?

rihadavid · 2019-10-01T22:11:52Z

I tried the same setting and the bug is still present

rihadavid · 2020-03-12T11:28:14Z

@jonathanpeppers still not fixed

jonathanpeppers · 2020-03-12T13:55:03Z

@rihadavid I haven't seen this issue myself in a long time.

What version of Visual Studio and Xamarin.Android are you using right now? Are you using any other extensions like ReSharper, etc.?

rihadavid · 2020-03-12T14:21:29Z

VS 16.4.5, Xamarin.Android 10.1.4.0, no extensions

jonathanpeppers · 2020-03-12T16:06:21Z

@rihadavid can you try the 16.5 preview?

There was an issue where the Android designer was running MSBuild targets in parallel, which can cause random build errors. That fix is only in 16.5 and higher.

It is not an issue in this repo, but if you can confirm if it is fixed or not we can close this, thanks!

rihadavid · 2020-03-17T19:30:31Z

Congrats, it's fixed in 16.5 stable release! It only took 16 months 🤣 Thanks anyway! 👍

jonathanpeppers · 2020-03-17T19:43:08Z

It only took 16 months

I would compare us to the last time you sent a bug to Android Studio and it actually got fixed. 16 months is less than infinity. 👀 😄
