如何使用 msbuild 命令忽略错误并成功构建？

Question

I have tried these command to ignore the error messages by using msbuild command, but it doesn't work.

msbuild /property:ContinueOnError=true E:...../xxx.sln

I got error messages like

GRGVTMWorkflowImp.cs(52,10): error CS0246: The type or namespace name 'GrgCreateFunctionAttribute' could not be found (are you missing a using directive or an assembly reference?) [E:\Fortify_Scan\src\AP1\VTM\20220607\20220601\GRGVTMBusinessService\GRGVTMWorkflow\GRGVTMWorkflow.csproj] GRGVTMWorkflowImp.cs(36,6): error CS0246: The type or namespace name 'GrgComponent' could not be found (are you missing a using directive or an assembly reference?)

I know what these error messages means but I still want the project can be build successfully.

Is it possible to ignore those error messages by using msbuild command or any other way to do it?

Answer 1

According to the Microsoft docs I get the impression that ContinueOnError is purely a property for MSBuild Tasks. While it is true that you're entering the build process via MSBuild, at some point the compiler csc.exe will be called.
I didn't find any information whether the compiler also supports this property. But I doubt it, because what should the compiler do with a project that is obviously corrupt (missing dependencies)? My assumption and expectation - fail fast.

Refer to MSBuild command line reference we can see that “-property:name=value” just can set or override the specified project-level properties but ContinueOnError is an attribute of task, so it doesn't work to change the value of ContinueOnError.

If you want to change the value of ContinueOnError you can write a task to define ContinueOnError=true such as:

<Task 
    Parameter1="Value1" ContinueOnError=" true ">
</Task>

or use Directory.Build.targets to customize your build .
