MSBuild -m fails on project import RemObjects.Elements.Echoes.targets

Hello,
we are facing this problem while trying to move projects from RemObjects.Elements.Echoes.Legacy.targets to RemObjects.Elements.Echoes.targets
Project building fails on clean while building via msbuild with -m (parallel) switch:

Try this command on a vs solution attached :
msbuild “TCElements.sln” -m -p:Configuration=Debug -t:clean;build
Throws
C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\MSBuild\RemObjects Software\Elements\RemObjects
.Elements.Echoes.targets(53,3): EBuild error : Project Reference ‘…\ClassLibrary1\ClassLibrary1.csproj’ could
not be resolved for target ‘Echoes’ (Echoes .NET anycpu). [D:\TescoTools\OtherProjects\TCElements\TCElements\Cla
ssLibrary2\ClassLibrary2.elements]

Works correctly with …Legacy.targets or without -m switch. Thank you for investigation.

What does -m do?

Ah, multi-threaded build. What I guess is happening is that MSBuild will/might try tho build the .elements project before the .csproj is done, and the .dll does not exist at the hint path yet. Apparently MSBuild does not auto-infer the dependency, as I does when. using legacy (actual MSBuild). We’ll need to see if/how we can fix that — in the mean time, work around should be to set an explicit dependency between the two projects in the Solution file.

Thanks, logged as bugs://83650

Using your project, fixed the references to the TescoSW*.dll in ClassLibrary4.elements and using the msbuild command line above works fine. What step am I missing?

Don’ know - there is nothing to miss :smiley:
There is a sln with tescosw refrences removed but it is irrelevant.
Which version of msbuild are you using ? Mine is:

C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise>msbuild -version
Microsoft (R) Build Engine version 16.4.0+e901037fe for .NET Framework

16.4.0.56107

And EBuild version:

Not sure if it is relevant but for me it looks like a target resolution problem. When specifying tragets=clean;build. Projects built at tree leaves level are reporting processig of clean;build targets that is correct, but nested projects are reporting processing of default target.
Would be stupid, BUT Isnt posiible that nested projects are jusit being build instead of cleaned as others on leaves ? Makes sense the absence of output libraries then.

From output:

“D:\TescoTools\OtherProjects\TCElements\TCElements\TCElements.sln” (clean;build target) (1) ->
“D:\TescoTools\OtherProjects\TCElements\TCElements\ClassLibrary2LegacyDep\ClassLibrary2LegacyDep.elements” (Clean target) (4) ->
“D:\TescoTools\OtherProjects\TCElements\TCElements\ClassLibrary2Legacy\ClassLibrary2Legacy.elements” (default target) (5:2) ->

If so, that’d be MSBuild’s issue :frowning:

Ok, looking at this again. could you do me a few favors:

(a) does the issue persist with JUST ClassLibrary1 and ClassLibrary2 in the solution, as well (wince those are the only two projects involved in the bug), or only if there’s others

(b) the project ref looks like this:

    <ProjectReference Include="..\ClassLibrary1\ClassLibrary1.csproj">
      <Name>ClassLibrary1</Name>
      <Project>{7526b200-53c7-469f-afb1-34706587dd68}</Project>
      <Private>True</Private>
      <HintPath>..\ClassLibrary1\bin\Debug\ClassLibrary1.dll</HintPath>
    </ProjectReference>

which seems fine does ..\ClassLibrary1\bin\Debug\ClassLibrary1.dll exist before the build starts/ does it exist afterwards?

(c ) can you delete ./bin and ./obj, add <Debug>True</Debug> as setting to then Elements project (this forces the most detailed logging output from the MSBuild-hosted EBuild) and then to a build with -m and the highest level of MSBuild log verbosity and send me that log file? (assuming the error hits during that build).

thanx!

I’m tracing thru what happens for the resolve for me now, here, and all goes as it should:

  • the project builds on its own, not part of a full SLN (as far as ebuild knows)
  • the reference to ClassLibrary1 holds an “UnsupportedProject”; expected
  • that project was not het build (expected)
  • EBuild looks for a FinalOutput.xml in a few places finds none (expected, since this isn’t build with EBuild)
  • EBuild emits these two messages (expected:
   Project 'ClassLibrary1' referenced from 'ClassLibrary2' is not enabled and has no cached final output. Falling back to hint path.
D: Cache file '/Users/mh/Library/Application Support/RemObjects Software/EBuild/Obj/ClassLibrary1-2AD756A0DC82282EBE1AD3667AB0F0F05A975755/Unknown/FinalOutput.xml' does not exist.
  • EBuild looks at the HintPath for the reference, as seen above, and expands it to /Users/mh/Downloads/TCElements 2/ClassLibrary1/bin/Debug/ClassLibrary1.dll on my local system.

if the file exists, the reference resolves ok. if I delete the file and build again, it fails with the same error you report (expected, of course).

IOW, EBuild is doing everything exactly as it should, given these inputs. The only explanation inhale for the error is that the .dll actually does not exist at the hunt path, at that time (which is out of my control of course, coz MSBuild/VC# are generating that file.

So that brings me back to one of two assumptions, either

(a) MSBuild doesn’t correctly know to build the VC# project first (and hold build of the Elements one until that is done), as woudl be needed since the project depends on the result of the other

or

(b) MSBuild is doing something else wrong.

Hopefully a full log will shed light…

From: Support for conditional compilation symbols

Ah, that one. It’s very odd, yeah. Neither me or Carlo could reproduce this; my gut feeling, from the log I saw, is seems me that somehow MSBuild doesn’t detect the dependencies between EBuild project references, and it somehow is building project B that depends on A, before A has finished (or started), IIRC.

Isn that’s the case, that bug should be hidden/worked around if you explicitly set dependencies inside the Solution file (BS has a dialog for that). you’d get sections like this in the .sln:

	ProjectSection(ProjectDependencies) = postProject
		{F8A2E4F6-C122-4A06-A27B-D77591E674CD} = {F8A2E4F6-C122-4A06-A27B-D77591E674CD}
		{4D283143-C13F-478F-A328-485E98D22CF1} = {4D283143-C13F-478F-A328-485E98D22CF1}
	EndProjectSection

Does that fix/hide the problem? If not, then the issue seems to be something else. I’ll review the other thread again as well.

  1. VS Dialog doesnt work for that, because references are already decalred in projects - the dialog and solution based references work only for references not decalred in projects. (Checks are already checked)

the cleaner/simpler a tests you could create where this fails for you (and a corresponding log), the better the chance that I can narrow this down w/o a local repro…

See the deatiled a diagnostic log files attachedmsbuildDiag.txt (403.4 KB) msbuildetailed.txt (168.6 KB)
The best i have.

an I get now with JUST the two projects? this log files are already next to incomprehensibly verbose, and it doesn’t help tom have 4 extra projects, one of which, to add insult to injury" shared part of the “classlibrary2” name, making it hard to search or filter. It also doesn’t seem like the <Debug> setting was on for these logs.

Solution composition is the key. Ive simplified the solution - removed ClassLibrary3 and 4 problem persists. But if you remove any of the rest projects then the problem is GONE.
Im sending he simplified solution and log files to compare process with -m:1 and -m:4 switches. Which could make difference at your side as well. With just -m msbuild decides the number of threads itself and that could differ on our systems.

C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise>msbuild "D:\TescoTools\OtherProjects\TCElements\TCElements\TCElements2.sln" -m:4 /t:Clean -p:configuration=Debug -v:d > D:\msbuildM4det.txt

Could you send me same logs from your working process ?

M1 seems to be good:

M4 still doesnt have the full diagnostic debug output, just
