Specify build verbosity for command line build using devenv - command-line

Is there a way to specify build verbosity for command line build using devenv?
I'm trying to make a test that builds our solution twice and the second time it builds it should output:
Build: 55 succeeded, 0 failed, 69 up-to-date, 1 skipped
But it should actually be 0 succeeded, x up-to-date.
I have the test running but ideally, I'd specify to build with verbosity = diagnostic for the second build so I can see why things are rebuilding.
I know msbuild has a verbosity flag, I don't think there is a way to set build verbosity using devenv, unless someone can give me a sneaky way.
I know that for building we generally should use msbuild, but I think devenv seems to do a better job of avoiding recompiling things that have already been compiled. So I want to use it for testing.

I believe you can't do it using devenv. But you could if you switch to msbuild.

How to activate "treat warning as error" for specific build definitions?

I would like to make my main branch TFS build definitions to treat warnings as errors so that the build fails when the projects are not error free. Since I do not want to activate "treat error as warning" in all project as a default, my first idea was to add a powershell script to my main build definition that substitues false with true in the line <TreatWarningsAsErrors>...</TreatWarningsAsErrors> in all csproj files it finds (something along the line of this). Is there any better/straighter way via some option as part of the build definition settings?
In the build definition specify /p:TreatWarningsAsErrors=True in the MSBuild argument field.
This will override any setting from the csproj files.
Unfortunately, there is no this kind of settings as part of the build definition.
However, you could be able to return warnings and errors from your powershell script using logging commands. With using task.logissue type=error you could fail the build task and then fail the build.
More details you could take a look at this similar question: Is it possible to raise and display build warnings from build steps using TFS 2015

Running Xcode unit tests during release build

I have a number of logic unit-tests (where my project files have a target membership of the App and AppTests). I want to add a call to xcodebuild test-without-building to my build system so that my unit-tests run for each build.
However, the tests cannot run on the release build (because release doesn't build for testing).
Is my only choice to build both the release version and the debug version during my build, so that I can use the debug version only to perform the tests? That's very different and very much worse to the other test frameworks I've used (GTest, Catch). Why can't the tests stand on their own?
The test-without-building command is not actually meant to "run the tests without rebuilding the app", but rather it's supposed to be used in tandem with the build-for-testing command.
Please refer to the "Advanced Testing and Continuous Integration" WWDC 2016 session for more info.
The gist is: use build-for-testing to build an .xctestrun file, which is then used by test-without-building to run the tests. This is particularly useful to run big suites across different machines, although I have never done it myself.
Now that we have established that you can't use test-without-building on its own, the only option to run the test from the command line and if they pass build a Release version is to use xcodebuild test, which is going to build the app.
As for the why does it need to be in Debug, I don't have a precise answer. In iOS land, at least in the teams I worked with, the difference between Debug and Release builds is always only on things like the options passed to the compiler in terms of optimization, the architectures to build on, and the type of code signing.
This means that the code that runs in Debug vs Release is exactly the same, and since we already established that you'll need to build the app twice, one to run the tests, one to generate the releasable version, running the tests in Debug seems acceptable.

Is it necessary to "clean" SBT before "stage" for production builds?

We are using Jenkins and SBT pluging to build, test and deploy our application. I see everywhere that people use "clean" command before "test" or "stage" which leads to very long compile times.
Is it necessary to clean everything for each build? What is the risk of using the incremental compiler for production builds?
I think it's a matter of taste. For continuous integration builds, it's ok to rely on the incremental compiler; if something fails I can investigate quite quickly.
But if, for whatever reason, the incremental compiler decides to ignore some changes (and it already happened to me in development), you may get some difficult bugs to resolve.
So, if you want something that's reproducible from a fresh code checkout; just run "clean" before everything else.
Most of the time, I configure jenkins with two build tasks: test builds, triggered by code changes, and packaging builds targeted for deployment and triggered periodically (or manually in some cases, with automatic deployment).
If the build script and/or command line to sbt have not changed then it should not be necessary to do clean.
I have been using Spark for several years - and it is one of the most complex sbt builds you can find. It works just fine to avoid doing clean as long as the build process itself (as embodied in the project/sbt build artifacts and the sbt command line) are the same as previous runs.

Having sbt to re-run on file changes - The `~ compile` equivalent for `run`

I know it's possible to re-compile or re-run tests on file changes. I want know to if it's possible to perform something similar for the run command. ~ run does not work. (That makes sense since the run never finishes).
Is there a way to create a task that watches for file changes, quit the running server and relaunch it ?
If not what other tool, would you suggest to get the same behaviour ?
You will have to bring in an external project like sbt-revolver

Is it possible to suppress NAnt's exec task's "[exec]" console output prefix

I'm trying to integrate Robot Framework (an acceptance testing framework) with TeamCity. In order to do this it needs to send messages to the console output which TeamCity will then read and return realtime test progress/results. I'm doing this by calling the command line to run the tests with a simple exec task. Everything seemed to be working other than I was only getting the results at the end of the run and not on the fly.
After a bit of struggling with NAnt I swapped to using MSBuild and everything worked first time.
I have what I need now, but for completeness I'd like to find out why I couldn't get it working with NAnt. As far as I can tell the issue is that NAnt is prefixing all console output with [exec]. Is it possible to suppress this?
I don't think the console output is configurable.
NAnt is open source: you could fork your own copy and/or submit a feature patch.
