Xamarin.Android项目上的Dotfuscator抛出错误 [英] Dotfuscator throwing error on Xamarin.Android project

问题描述

我按照步骤

I followed the steps to integrate Dotfuscator into my Xamarin.Android project as described here, but when it's time to build the project, I'm getting the following error:

"_ DotfuscatorXamarin_DetermineDefaultInputsTask"任务意外失败. 2> \ path \ to \ PreEmptive.Dotfuscator.Xamarin.targets(570,5):错误MSB4018:System.NullReferenceException:对象引用未设置为对象的实例. 2> \ path \ to \ PreEmptive.Dotfuscator.Xamarin.targets(570,5):错误MSB4018:at InlineCode._DotfuscatorXamarin_DetermineDefaultInputsTask.Execute()在\ path \ to \ AppData \ Local \ Temp \ eruovv3u.0.cs:line中106 2> \ path \ to \ PreEmptive.Dotfuscator.Xamarin.targets(570,5):错误MSB4018:位于Microsoft.Build.BackEnd.TaskExecutionHost.Microsoft.Build.BackEnd.ITaskExecutionHost.Execute() 2> \ path \ to \ PreEmptive.Dotfuscator.Xamarin.targets(570,5):错误MSB4018:位于Microsoft.Build.BackEnd.TaskBuilder.d__26.MoveNext()

我已经看过并且看过网上了，但是似乎没有人遇到这个问题.我认为问题与在首次构建时生成默认配置文件有关.有什么想法吗?

I have looked and looked online, but no one seems to be having this issue. I think the problem has something to do with generating the default configuration file on the first build. Any ideas?

推荐答案

更新:此问题已在较新版本的Dotfuscator中修复.请参阅免费的 Dotfuscator社区的详细说明. 以及商业许可的 Dotfuscator Professional .原始答案如下.

UPDATE: This issue has been fixed in newer versions of Dotfuscator. See the detailed instructions for the free Dotfuscator Community and for the commercially-licensed Dotfuscator Professional. The original answer follows below.

全面披露:我是PreEmptive Solutions的Dotfuscator开发人员，正在以这个角色回答这个问题.

Full Disclosure: I am a developer of Dotfuscator at PreEmptive Solutions, and am answering this question in that role.

是的，问题是目标文件(PreEmptive.Dotfuscator.Xamarin.targets)中默认的配置文件生成-对此感到抱歉.具体来说，构建集成正在尝试发现项目引用，但期望使用经典的MSBuild项目格式，而不是.NET Standard使用的新的最小格式.

You're right, the problem is the default config file generation in the targets file (PreEmptive.Dotfuscator.Xamarin.targets) - sorry about that. Specifically, the build integration is attempting to discover project references, but expects the classic MSBuild project format, not the new minimal one used by .NET Standard.

您可以按照以下方法解决此问题:

You can work around this issue as follows:

1. 在目标文件中，找到_DotfuscatorXamarinConfigTemplateLines属性，然后将其值(在CDATA部分中)复制到名为DotfuscatorConfig.xml的新文件中(或为项目文件中的DotfuscatorXamarinConfigFileName属性提供的任何值).与您的项目文件相同的目录.
2. 在Visual Studio中，以您要保护的配置(例如， AnyCPU | Release )构建您的项目一次.将会出错，因为新的配置文件尚无任何输入程序集，但是通过现在构建，我们将这些程序集放置在正确的位置来配置Dotfuscator.
3. 打开Dotfuscator的用户界面.
   • 对于Community Edition，从Visual Studio中，打开工具"菜单，然后选择"PreEmptive Protection-Dotfuscator".
   • 对于Professional Edition，请从开始"菜单中运行Dotfuscator Professional Edition.

1. In the targets file, locate the _DotfuscatorXamarinConfigTemplateLines property and copy its value (within the CDATA section) to a new file named DotfuscatorConfig.xml (or whatever value you supplied for the DotfuscatorXamarinConfigFileName property in your project file) in the same directory as your project file.
2. In Visual Studio, build your project once in a configuration you want to protect (e.g., AnyCPU|Release). It will error, because the new config file doesn't have any input assemblies yet, but by building now we get those assemblies in the right location for configuring Dotfuscator.
3. Open Dotfuscator's user interface.
   • For Community Edition, from Visual Studio, open the Tools menu and select PreEmptive Protection - Dotfuscator.
   • For Professional Edition, run Dotfuscator Professional Edition from the Start Menu.

• 用适当的目录替换Release，以适合您在步骤2中构建的配置.
• 您应选择与您的解决方案中的项目相对应的程序集，而不是选择框架中包含的第三方和程序集.

• Substitute Release with the appropriate directory for the configuration you built in step 2.
• You should select assemblies that correspond to projects in your solution, and not select third-party and assemblies that are part of the framework.

• 在Community Edition中，转到"构建设置"屏幕，然后选择"项目属性"标签.
• 在专业版中，转到"设置"标签，然后选择"设置>项目属性"屏幕.

• In Community Edition, go to the Build Settings screen and select the Project Properties tab.
• In Professional Edition, go to the Settings tab and select the Settings > Project Properties screen.

• 属性名称InDir，值obj\Release\DotfuscatorXamarin\dfin
• 属性名称OutDir，值obj\Release\DotfuscatorXamarin\dfout
• 属性名称ReportDir，值DotfuscatorReports\Release
• 用用于在步骤2中构建的配置的适当目录替换Release.请注意，OutDir和ReportDir指向的目录在磁盘上尚不存在.

• Property name InDir, value obj\Release\DotfuscatorXamarin\dfin
• Property name OutDir, value obj\Release\DotfuscatorXamarin\dfout
• Property name ReportDir, value DotfuscatorReports\Release
• Substitute Release with the appropriate directory for the configuration you built in step 2. Note that the directories pointed to by OutDir and ReportDir won't exist on-disk yet.
