如何对具有相同文件的目录进行HeatDirectory 2次或更多次? [英] How to HeatDirectory 2 or more times against directories with the same files?

问题描述

我一直在BeforeBuild目标的WiX安装程序项目中使用HeatDirectory任务来收集我们部署在客户端网络上的Web应用程序的文件.一直很棒.

I've been using the HeatDirectory task in our WiX installer project in the BeforeBuild target to harvest the files of a web application we deploy on the clients network. Been working great.

我现在想部署第二组文件，这恰好是一些文档，并且包含与先前HeatDirectory输出中存在的文件名称相同的文件.

I now want to deploy a second set of files, which so happens to be some documentation, and it contains files that are of the same name that exist in the previous HeatDirectory output.

我收到以下错误:

LGHT0293: Multiple files with ID 'Web.Config' exist.

我了解我为什么会收到错误，我想知道如何最好地解决它.

I understand why I am getting the error, I'm wondering how best to resolve it.

选项A :

将所有文件复制到目录中，并通过大量操作对其进行加热.

Copy all the files into a directory and run heat on them in one massive pass.

我之所以这样，是因为使用库存MSBuild任务很容易实现.我不喜欢它，因为它会创建一个庞大的ComponentGroup，而且如果我决定提供可选功能(如不安装某些东西)，我就不会.

I like this because it would be fairly easy to implement using stock MSBuild tasks. I dislike it because it would create one massive ComponentGroup and if I ever decided to make optional features (like not install something), I can't.

选项B :

遍历HeatDirectory任务的输出文件，并在所有Component ID和File Id的后面添加后缀.示例-web.config将变为web.config_DocumenationFiles

Iterate over the output file of the HeatDirectory task and append a suffix on all the Component ID and File Id's. Example - web.config would become web.config_DocumenationFiles

我喜欢它，因为它很干净.即，我可以稍后将其删除或将其添加到有问题的项目中，而不将其添加到没有问题的项目中.我不喜欢它，因为我不确定哪个进程"(或MSBuild任务)能够做到这一点.我认为我需要自定义任务.

I like this because it's clean; i.e. I can delete it later or add it to a project that's having the issue and not add it to projects that don't. I dislike it because I'm not sure what 'process' (or MSBuild task) is capable of doing this. I need a custom task I think.

其他选项:吗?

想法?

推荐答案

我看到有人在三年后出现并对此表示支持.我以为我会回来并声明我仍在使用选项B，这是一个自定义MSBuild任务来解决该问题.

I see someone has come along and upvoted this three years later. I thought I'd come back and state that I'm still using Option B, a custom MSBuild task to resolve the issue.

我对另一则帖子进行了评论，其中包含有关该问题的更多详细信息，并认为我会移动/复制实现在这里，以防万一.

I made a comment on another post about the issue with more details and thought I'd move/copy my implementation over here in case it's helpful.

我已经解决了此问题，方法是创建一个自定义构建任务，该任务在HeatDirectory任务之后运行，以将后缀附加到Id属性.

I had solved it by creating a custom build task to run after the HeatDirectory task to append a suffix to the Id attribute.

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

AddSuffixToHeatDirectory任务就是这样

The AddSuffixToHeatDirectory task is 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's 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; }
}

希望有帮助.今天，我仍在使用此方法，而且还没有完成研究Transform或扩展HeatDirectory的工作.

Hope that helps. I'm still using this method today and I've not done the legwork to look into a Transform or extending HeatDirectory.
