msbuild.exe is not recognized command after build in Jenkins

For the latest version of jenkins (3.0), you have to configure MSBuild in in the Tools>Manage Jenkins menu. Name a job here eg: msbuild. Once that is done, go to the job. Under the MSBuild module select the build (in this case msbuild) and now kick off the job. You should be good to go.

For the newer version of Jenkins, this option is available under this section ..

Manage Jenkins -> Global Tool Configuration ->  MSBuild
