[Bug] 未找到导入的项目“C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v11.0\WebApplications\Microsoft.WebApplication.targets”

This is very easy to do. Open your build definition and go to the "Process" page. Then under the "3. Advanced" group you have a property called "MSBuild Arguments". Place the parameter there with the following syntax "/p:VisualStudioVersion=12.0". Of course without the quotes. If you have more parameters, separate them with a space and not a comma.

echo off

path %SYSTEMROOT%\Microsoft.NET\Framework\v4.0.30319\

msbuild.exe .\src\ElectricManagement.sln /t:Rebuild /p:Configuration=Release /p:VisualStudioVersion=12.0
::/l:FileLogger,Microsoft.Build.Engine;logfile=Build1.log

msbuild  .\src\ElectricManagement.Web\ElectricManagement.Web.csproj /t:ResolveReferences;Compile /t:_WPPCopyWebApplication /p:Configuration=Release /p:VisualStudioVersion=12.0 /p:WebProjectOutputDir=..\..\Release
::/l:FileLogger,Microsoft.Build.Engine;logfile=Build2.log

echo 编译当前项目完毕
pause

这个时候发现项目文件打不开，无法重新加载项目，这个时候可以尝试手动编译一下项目。
