Exclude file and folder properties only accept one file or folder

[jsnplank]

`gulp.task("package-web", function (cb) {
console.log("[Create Web Deploy package]");
gulp.src(paths.expenseWebSitePath + "/Deployment/*.xml")
.pipe(gulp.dest(paths.expenseWebDeployPath));

var msbuild = new _msbuild(cb);
msbuild.sourcePath = paths.expenseWebSiteProject;
msbuild.toolsVersion = config.vsToolsVersion;
msbuild.configuration = config.environment.buildConfiguration;
//targets
msbuild.overrideParams.push('/target:Clean;Build;Package');
msbuild.overrideParams.push('/p:VisualStudioVersion=' + config.vsVersion);
msbuild.overrideParams.push('/p:DeployOnBuild=false');
msbuild.overrideParams.push('/p:DeployTarget=PipelinePreDeployCopyAllFilestoOneFolder');
msbuild.overrideParams.push('/p:DeployIISAppPath=' + config.iisAppPaths.web);
msbuild.overrideParams.push('/p:AutoParameterizationWebConfigConnectionStrings=false');
msbuild.overrideParams.push('/p:PackageLocation=' + paths.expenseWebDeployPath);
//msbuild.overrideParams.push('/p:ExcludeFilesFromDeployment=".;.js;.json;.csproj;packages.config;paylocity-grey.png;Web.*.config"');
//msbuild.overrideParams.push('/p:ExcludeFoldersFromDeployment=bower_components;Claims;Controllers;Framework;Initialization;Models;Properties;ViewModels;src');
msbuild.overrideParams.push('/p:ExcludeFoldersFromDeployment=bower_components');
msbuild.overrideParams.push('/p:FilesToIncludeForPublish=AllFilesInProjectFolder');
msbuild.overrideParams.push('/verbosity:minimal');

msbuild.package();
});`

The commented out "ExcludeFoldersFromDeployment" and "ExcludeFilesFromDeployment" properties fail. It has to do with supplying multiple file types. If you use a single entry, like the uncommented 'ExcludeFoldersFromDeployment' statement it works OK.
