How to run PyLint for .pyproj when building it with MsBuild?

I need to run PyLint to validate my Python files code when building. The python files are under .pyproj (I use Python tools for Visual Studio 2015). How I can do that?

Update:

So far I have code like this:

<Target Name="PythonRunPyLint">
    <PropertyGroup>
        <PyLintWarningRegex><![CDATA[^(?<filename>.+?)\((?<line>\d+),(?<column>\d+)\): warning (?<msg_id>.+?): (?<message>.+?)$]]></PyLintWarningRegex>
    </PropertyGroup>
    <RunPythonCommand Target="pylint.lint"
                             TargetType="module"
                             Arguments="&quot;--msg-template={abspath}({line},{column}): warning {msg_id}: {msg} [{C}:{symbol}]&quot; -r n @(Compile, ' ')"
                             ExecuteIn="console"
                             WorkingDirectory="$(MSBuildProjectDirectory)"
                             WarningRegex="$(PyLintWarningRegex)"
                             RequiredPackages="pylint&gt;=1.0.0"> 
        <Output TaskParameter="ConsoleOutput" PropertyName="OutputText" />
        <Output TaskParameter="ConsoleError" PropertyName="ErrorText" />
    </RunPythonCommand>
</Target>

But when I run msbuild I get output and there's 0 warnings, why regex does not parse warnings (regex is taken from Microsoft.PythonTools.targets and it works when doing Tools > Run PyLint in Visual studio)?

C:\>msbuild TestPylint.pyproj /t:Build

Solution

I ended up with the following code:

<Target Name="Build">
    <RunPythonCommand Target="pylint.lint"
                         TargetType="module"
                         Arguments="&quot;--msg-template={path}({line},{column}): warning: [{msg_id}{obj}] {msg}&quot; -r n @(Compile, ' ')"
                         ExecuteIn="console"
                         WorkingDirectory="$(MSBuildProjectDirectory)"
                         RequiredPackages="pylint&gt;=1.0.0"
                         ConsoleToMSBuild="true"
                         ContinueOnError="true">
          <Output TaskParameter="ConsoleOutput" ItemName="OutputText" />
          <Output TaskParameter="ConsoleError" PropertyName="ErrorText" />
    </RunPythonCommand>
     <WriteLinesToFile
            File="lint_output.txt"
            Lines="@(OutputText)"
            Overwrite="true"
            Encoding="Unicode"/>
     <Exec ContinueOnError="true"
          IgnoreExitCode="true"
          Command='type lint_output.txt'/>
  </Target>

Now msbuild TestPylint.pyproj /t:Build counts errors/warnings also errors/warnings are shown on Visual Studio Error List window.

Task WriteLinesToFile is used because I did not found any other way for msbuild to recognize errors/warnings <Exec Command="echo $(OutputText)/> (if OutputText is property) simply does not work!
