nar and appveyor

[Fabrice Bacchella]

I'm trying to build an app using AppVeyor : https://github.com/fbacchella/JPDH/tree/maven

But nar seems unable to find MSVC.

First it failed with:

    [ERROR] Failed to execute goal com.github.maven-nar:nar-maven-plugin:3.5.2:nar-compile (default-cli) on project JPDH: msvc.version not specified and no VS<Version>COMNTOOLS environment variable can be found -> [Help 1]

org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal com.github.maven-nar:nar-maven-plugin:3.5.2:nar-compile (default-cli) on project JPDH: msvc.version not specified and no VS<Version>COMNTOOLS environment variable can be found

So I tried to prepare the environment as explained in https://docs.microsoft.com/fr-fr/cpp/build/setting-the-path-and-environment-variables-for-command-line-builds

And added this commands in my appveyor.yml:

  - cmd: cd "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC"

  - cmd: vcvarsall amd64

  - cmd: cd "C:\projects\jpdh"

But it provided no help. It fails.

I tried to add

  - cmd: mvn nar:nar-compile -X

To have more informations, and now I'm getting:

[DEBUG] linker original name not exist

[DEBUG] NAR - output: 'C:\projects\jpdh\target\nar\JPDH-1.2-SNAPSHOT-amd64-Windows-msvc-jni\lib\amd64-Windows-msvc\jni\JPDH-1.2-SNAPSHOT'

And it finally fails because:

            [DEBUG] C:\projects\jpdh\VC\bin\amd64\cl  ...

Of course, it can find VC\bin\amd64\cl in this path. What I'm doing wrong ?
