Compiling many typescript files at once resulted in File not found error

问题

We have an MSBuild script which we use to compile all our .ts files in our project. First we create a propery group containing all the .ts files;

<ItemGroup>
   <AllTypeScriptFiles Include="XXXXX\Scripts\**\*.ts;" Exclude="XXXX\Scripts\**\*.d.ts;" /> 
</ItemGroup>

Then we dump this file list to an input file and run tsc.exe;

<WriteLinesToFile
    File="typescriptcompiler.input"
    Lines="@(AllTypeScriptFiles)"
    Overwrite="true"
    Encoding="Unicode"/>    

<Exec Command="&quot;$(MSBuildProgramFiles32)\Microsoft SDKs\TypeScript\$(TypeScriptVersion)\tsc&quot; --target ES5 @typescriptcompiler.input"
      CustomErrorRegularExpression="\.ts\([0-9]+,[0-9]+\):(.*)"
      IgnoreExitCode="true" >
</Exec>

Now, the output states that some files can not be found;

Error reading file "XXXXX.ts": File not found

This happens to some files, but if I run tsc.exe giving the exact same path as the error message I get no errors and the file is compiled.

If I rather compile each file in sequence instead:

<Exec Command="&quot;$(MSBuildProgramFiles32)\Microsoft SDKs\TypeScript\$(TypeScriptVersion)\tsc&quot; --target ES5 &quot;%(AllTypeScriptFiles.Identity)&quot;"
      CustomErrorRegularExpression="\.ts\([0-9]+,[0-9]+\):(.*)"
      IgnoreExitCode="true" >
</Exec>

All files are compiled without problems, except it takes 5 minutes instead of 10 seconds...

Typescript version 0.8.3 solves this problem! No more erros.

I am now able to compile all the files with one go:

<ItemGroup>
   <AllTypeScriptFiles Include="XXXXX\Scripts\**\*.ts;" Exclude="XXXX\Scripts\**\*.d.ts;" /> 
</ItemGroup>

<WriteLinesToFile
    File="typescriptcompiler.input"
    Lines="@(AllTypeScriptFiles)"
    Overwrite="true"
    Encoding="Unicode"/>    

<Exec Command="&quot;$(MSBuildProgramFiles32)\Microsoft SDKs\TypeScript\$(TypeScriptVersion)\tsc&quot; --target ES5 @typescriptcompiler.input"
      CustomErrorRegularExpression="\.ts\([0-9]+,[0-9]+\):(.*)">
</Exec>

The easiest way to do this is to pick your top level file (for example app.ts) and set an output file on the compiler...

  <Target Name="BeforeBuild">
    <Exec Command="&quot;$(PROGRAMFILES)\Microsoft SDKs\TypeScript\$(TypeScriptVersion)\tsc&quot; --out final.js --target ES5 @(TypeScriptCompile ->'&quot;%(fullpath)&quot;', ' ')" />
  </Target>

TypeScript will walk all the dependencies and compile it all into final.js.

Note - I recommended this way because you aren't using a --module flag. I would give a different answer for commonjs or amd programs.

I have just changed my TypeScript workflow to use this based on ideas from Mark Rendle.

Alternatively, you can use the following to compile all .ts files...

  <ItemGroup>
    <TypeScriptCompile Include="$(ProjectDir)\**\*.ts" />
  </ItemGroup>
  <Target Name="BeforeBuild">
    <Exec Command="&quot;$(PROGRAMFILES)\Microsoft SDKs\TypeScript\0.8.1.1\tsc&quot; --target ES5 @(TypeScriptCompile ->'&quot;%(fullpath)&quot;', ' ')" />
  </Target>
