jenkins - WarningsPlugin not Collecting warnings from MSBuild

Question

I am experimenting with a Multibranch job. Building the solution works, but parsing the warnings generated by the build fails.

this is my Jenkinsfile:

node {
    stage ('Checkout')
    {
        checkout scm
    }

    stage ('Build')
    {
        bat ""${tool 'MSBuild VS2013'}" Solution.sln /p:Configuration=Release /p:Platform="Any CPU" /p:ProductVersion=1.0.0.${env.BUILD_NUMBER}"
    }

    stage ('Warnings')
    {
        step([$class: 'WarningsPublisher', canComputeNew: false, canResolveRelativePaths: false, defaultEncoding: '', excludePattern: '', healthy: '', includePattern: '', messagesPattern: '', parserConfigurations: [[parserName: 'MSBuild']], unHealthy: ''])
    }
}

I get this Exception from the Warnings Plugin:

Answer 1

Solved the problem by writing the output from msbuild to a Textfile and then using this file as input for the warnings plugin

stage ('Checkout')
{
    checkout scm
}

stage ('Build')
{
    bat ""${tool 'MSBuild VS2013'}" Solution.sln /p:Configuration=Release /p:Platform="Any CPU" /p:ProductVersion=1.0.0.${env.BUILD_NUMBER} > msbuild.log 2>&1"
    bat " type msbuild.log"
}

stage ('Warnings')
{
    step([$class: 'WarningsPublisher', canComputeNew: false, canResolveRelativePaths: false, defaultEncoding: '', excludePattern: '', healthy: '', includePattern: '', messagesPattern: '', parserConfigurations: [[parserName: 'MSBuild', pattern: 'msbuild.log']], unHealthy: ''])
}
