HeatDirectory Compiler Duplicated

Question

There are several modules in my project. The source files for them are generated by heatdirectory.

 <HeatDirectory DirectoryRefId="ServerAdminService" OutputFile="Source\ServerAdminServiceSource.wxs" Transforms="Filter.xsl" Directory="..\..\Server\ServerServiceManager\bin\Debug\" PreprocessorVariable="var.ServerAdminServicePath" ComponentGroupName="ServerAdminServiceGroup" ToolPath="$(WixToolPath)" SuppressCom="true" SuppressFragments="true" SuppressRegistry="true" SuppressRootDirectory="true" AutoGenerateGuids="true" GenerateGuidsNow="false">
</HeatDirectory>
<HeatDirectory DirectoryRefId="ServerAdminService" OutputFile="Source\ServerAdminClientSource.wxs" Transforms="Filter.xsl" Directory="..\Setup\C24.ServerAdmin.UI\bin\Debug\" PreprocessorVariable="var.ServerAdminClientPath" ComponentGroupName="ServerAdminClientGroup" ToolPath="$(WixToolPath)" SuppressCom="true" SuppressFragments="true" SuppressRegistry="true" SuppressRootDirectory="true" AutoGenerateGuids="true" GenerateGuidsNow="false">
</HeatDirectory>

It works great. I need to install them in one directory. But they use several libraries, which are presented in both modules, and after generating the source files, they consist of a component with a duplicate identifier. Actually, I don’t know what to do. Does anyone have an idea?

I had the same problem .

I solved this by creating a custom build task to run after the HeatDirectory task to add a suffix to the Id attribute.

<AddSuffixToHeatDirectory File="ReportFiles.Generated.wxs" Suffix="_r" />

AddSuffixToHeatDirectory task as such

    public class AddSuffixToHeatDirectory : Task
{
    public override bool Execute()
    {
        bool result = true;

        Log.LogMessage("Opening file '{0}'.", File);
        var document = XElement.Load(File);

        var defaultNamespace = GetDefaultNamespace(document);

        AddSuffixToAttribute(document, defaultNamespace, "Component", "Id");
        AddSuffixToAttribute(document, defaultNamespace, "File", "Id");
        AddSuffixToAttribute(document, defaultNamespace, "ComponentRef", "Id");
        AddSuffixToAttribute(document, defaultNamespace, "Directory", "Id");

        var files = (from x in document.Descendants(defaultNamespace.GetName("File")) select x).ToList();

        Log.LogMessage("Saving file '{0}'.", File);
        document.Save(File);

        return result;
    }

    private void AddSuffixToAttribute(XElement xml, XNamespace defaultNamespace, string elementName, string attributeName)
    {
        var items = (from x in xml.Descendants(defaultNamespace.GetName(elementName)) select x).ToList();
        foreach (var item in items)
        {
            var attribute = item.Attribute(attributeName);
            attribute.Value = string.Format("{0}{1}", attribute.Value, Suffix);
        }
    }

    private XNamespace GetDefaultNamespace(XElement root)
    {
        // I pieced together this query from hanselman post.
        //  http://www.hanselman.com/blog/GetNamespacesFromAnXMLDocumentWithXPathDocumentAndLINQToXML.aspx
        // 
        // Basically I'm just getting the namespace that doesn't have a localname.
        var result = root.Attributes()
                        .Where(a => a.IsNamespaceDeclaration)
                        .GroupBy(a => a.Name.Namespace == XNamespace.None ? String.Empty : a.Name.LocalName, a => XNamespace.Get(a.Value))
                        .ToDictionary(g => g.Key, g => g.First());
        return result[string.Empty];
    }

    /// <summary>
    /// File to modify.
    /// </summary>
    [Required]
    public string File { get; set; }

    /// <summary>
    /// Suffix to append.
    /// </summary>
    [Required]
    public string Suffix { get; set; }
}
