Is jdkIncludePath suppose to do something?

[kwhat]

I am seeing errors like fatal error: jni.h: No such file or directory when trying to use jdkIncludePath in a compile goal. What does this configuration do, and more importantly why doesn't it add an include (-I) to the C src compilation? If this is for something else and I still need to add a <source><directory>${java.home}/include</directory></source> why does it even exist?

@kwhat may want to take a look at this #17

Yah, I was reading that earlier... maintaining backward compatibility is really a lost cause <1.8 || <11. It seems that jdkIncludePath really doesn't do anything meaningful unless you specify <javahOS/>, even when only compiling native src without javah.

I finally got it working, took a bit of monkeying but it works well, thanks!

I ran across a similar issue, and I am curious to know which workaround you ended up using.

It turns out that for Java 11 at least (but this likely applies to later versions as well), the default value for jdkIncludePath of ${java.home}/../include that is assumed by this plugin is no longer correct, hence the error. You have to explicitly declare it in your pom as ${java.home}/include.
