nar-compile cannot find mt.exe with Visual Studio 2017

bribass commented 5 years ago

The attached nar-issue.zip contains a project that builds a JAR and a JNI library. When built on a Windows 10 machine with Visual Studio 2017 (version 15.9.7), nar-compile fails to build the DLL because it cannot find mt.exe.

If I add the directory C:\Program Files (x86)\Windows Kits\10\bin\10.0.17763.0\x64 (the directory in which mt.exe resides) to the PATH, nar-compile succeeds. However, since nar-maven-plugin automatically determines paths for other parts of nar-compile (i.e., the compiler and the linker), this is not expected (or desired) behavior.

Attached are the following files:

nar-issue.zip: A project that provides a minimal reproduction of the issue.
mvn_package.log: The result of running mvn -X package.
Dockerfile.txt: A Dockerfile for building an image (in conjuntion with Docker Desktop for Windows) that contains the environment that allows for the issue to be reproduced.

OK, now I feel stupid. This failure is with version 3.6.0 (the latest available version on Maven Central). I tried again with the current master, and everything is working as expected. Is there any estimation on when a new version (either the 3.7.0 release that is implied by the presence of a tag in the repository, or a 3.7.1 containing the current master) will be available?
