使用roslyn代替MSBuild完成解決方案編譯


原本我是使用批處理調用 MSBuild 完成解決方案編譯的,新版的 MSBuild 在 Visual Studio 2015 會自帶安裝.

當然在Visual Studio 2015 中,MSBuild 是一個獨立的安裝包,可以單獨安裝,而無須安裝 Visual Studio 2015.

剛開始,我在 Windows Server 2008 R2 上使用 MSBuild 編譯使用 .NET Framework 4.5.2 版本 開發的項目,也不是那么順利的.

期間,遇到並且解決了很多問題,依次順序為:

1. Windows Server 2008 R2 沒有安裝 .NET Framework 4.5.2 ,這個安裝 .NET Framework 4.5.2 就解決了.

2. Windows Server 2008 R2 上沒有可以編譯 .NET Framework 4.5.2 版本項目的  MSBuild .

    原因是 MSBuild 的版本問題,因為 .NET Framework 4.0 自帶的 MSBuild 不能識別 C# 6.0 語法特性.

    對於這個問題,當時很糾結,因為那時我還不知道 MSBuild 有了獨立安裝包,以為想要用新版的 MSBuild 必須在服務器上安裝 Visual Studio 2015.

    后來我在visualstudio.com上找到了 MSBuild 獨立安裝包, 名為 Microsoft Build Tools 2015, 所以這個問題也算是解決了.

3. 在Windows Server 2008 R2 上用 MSBuild 2015 居然要安裝 .NET Framework 4.5.2 SDK ?

    這個也是安裝 .NET Framework 4.5.2 Developer Pack 就可以解決了, 不過我沒安裝, 而是直接從本機上拷貝一份到服務器上, 存放位置和本機的路徑一樣.

    只要安裝了 Visual Studio 2015 ,那么 SDK 的位置一般在(x86系統)C:\Program Files\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.2 ,

    (x64系統)C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.2.

4. 由於在項目中引用了第三方組件,而第三方組件又引用了一些 .NET Framework 4.0 的 dll, 而在引用第三方組件的項目中沒有引用第三方組件中引用了的 .NET Framework 4.0 的 dll.

    一般情況下,用 Visual Studio 2015 進行編譯是沒有問題的. 當使用批處理進行編譯的時候, 問題就來了, 拋出了一對錯誤, 諸如 System.Object, Object 之類的錯誤, 比如:

    error CS0012: The type 'Object' is defined in an assembly that is not referenced.
    You must add a reference to assembly 'System.Runtime, Version=4.0.0.0, Culture=neutral,
    PublicKeyToken=b03f5f7f11d50a3a'.

    The type 'System.Object' is defined in an assembly
    that is not referenced. You must add a reference to assembly 'System.Runtime,
    Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

    發現同一依賴程序集的不同版本之間存在沖突

    解決辦法就是在引用了第三方組件的項目中, 引用第三方組件中引用了的 .NET Framework 4.0 的 dll. 這樣批處理是可以成功執行完成編譯的了. 但 Visual Studio 2015 編譯卻報錯了.

    於是折騰了一番, 敲定解決辦法是:

        1.拷貝System.Runtime.dll到解決方案目錄(隨意, 我的是Library目錄)下.

        2.直接打開需要引用的csproj文件,向其中添加:

<Reference Include="System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">
<HintPath>..\..\Library\System.Runtime.dll</HintPath>
<Private>True</Private>
</Reference>

        3.向 Web.Config 的 runtime --> assemblyBinding 節添加:

<dependentAssembly>
<assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
</dependentAssembly>

    到這里, VS 編譯 和 批處理編譯都沒問題了.

 

MSBuild 批處理編譯 .NET Framework 4.5.2 項目的命令行

ECHO 初始化變量
SET ProgramPath="C:\Program Files"
IF EXIST %windir%\SysWOW64 SET ProgramPath="C:\Program Files (x86)"
SET MsBuildExe="%ProgramPath%\MSBuild\14.0\Bin\MSBuild.exe" /t:rebuild /verbosity:q /p:Configuration=Release;FrameworkPathOverride="%ProgramPath%\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.2" /l:FileLogger,Microsoft.Build.Engine;verbosity=normal;encoding=utf-8;append=true;logfile=Build.log

ECHO 編譯解決方案
%MsBuildExe%
"C:\work\CRM\CRM.VS2015.sln"

大功告成, 這樣就可以編譯 .NET Framework 4.5.2 項目了.

可是后來我為什么要換成 roslyn 編譯呢? 這也是有原因的!

經過上面的折騰,我成功用批處理編譯 .NET Framework 4.5.2 項目后, 我並未滿足, 我想要更方便的, 無須安裝那么多操蛋的東西, 只需要有運行時環境就可以了, 行不行?

答案當然是可以的, 那便是近年漸火的 roslyn 開源項目.

 接下來, 我嘗試使用 roslyn 幫助我完成編譯 .NET Framework 4.5.2 項目.

首先, 用 Visual Studio 2015 Update 1 新建一個目標框架為 .NET Framework 4.5.2 的控制台 C# 項目, 為什么一定要 Update 1, 不解釋, 照做就對了.

        然后對這項目右鍵屬性, 更改程序集名稱為 RBuild .

其次, 在 Visual Studio 菜單欄中 工具 --> NuGet 包管理器  --> 程序包管理器控制台.

    在控制台輸入指令: Install-Package Microsoft.CodeAnalysis 以及 Install-Package Microsoft.Net.Compilers.

    安裝成功后,在項目中會有個包管理文件 packages.config

內容如下:

編譯完成后, 就可以在 CMD 命令行提示符用了.

這是 help.txt 內容以及用法:

Provide help information for commands.

RBuild [-s] [-o] [-p]

-s —— Solution
Path, required.
Use: -s "C:\work\CRM\CRM.VS2015.sln"
-o —— Output Directory
, required.
Use: -o "E:\work\CRM\Build\WebAPI\bin"
-p —— Build Properties
, required.
Use: -p Configuration=Release;FrameworkPathOverride=C:\Program Files\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.2;key=value
-l —— Output Log
Path, not required.
Use: -l "log.txt"

目前我只知道 roslyn 可以編譯項目, 但編譯后拷貝相關的非代碼文件到相應目錄這個功能卻沒有發現哪里有, 只能通過批處理自己拷貝了.

我的用法

ECHO 開始編譯解決方案
BuildTools
\RBuild.exe -s "..\..\CRM\src\CRM.VS2015.sln" -o "CRM\bin" -p Configuration=Release -l Build.log
