pljava-so: TypeError: null is not an Object in <eval>

[const1995]

Hello, everyone!
While compiling pljava I have error:
Failed to execute goal org.postgresql:pljava-pgxs:1.6.7:scripted-goal (build-shared-object) on project pljava-so: TypeError: null is not an Object in at line number 315 -> [Help 1]
Environment:
OS Windows 10
PostgreSQL 16
pljava 1.6.7
maven 3.5.4
g++ 13.2.0
javac 21.0.2

How can I fix this bug?

Hi!

This appears to be the same as #485, and the build script did not match your build environment to either Windows MSVC or Windows MinGW, and as a result there are no build rules selected (giving a null result, instead of something more helpful like a "no build rules matched" message).

Depending on whether you have installed PostgreSQL that was built with MSVC (like the EDB package) or built with MinGW, you can read the corresponding probe test in pljava-so/pom.xml to see why the probe did not match in your environment. It could, for example, be looking for an environment variable that isn't set.

You are absolutely right. I compiled pljava in vcvars64.bat command line utility from MSVC 2017
Thank you very much!
