Please try to use the Maven plugin as per the JavaCPP Presets or Gradle JavaCPP:

I looked through it and some other stuff but to be honest I am still quite confused about how I'm supposed to use it.. I'd like to ask is the plugin able to parse native header files or does that have to be done with the javacpp.jar ?

yeah I also gave that a read before making a post. Still couldn't quite get it but after giving it another look I decided to take a peek in the pom.xml that's in the base javacpp-presets and I think I found what I needed, but it still doesn't work. More specifically this part seems to not be working:
<execution>
<id>javacpp-parser</id>
<phase>generate-sources</phase>
<goals>
<goal>parse</goal>
</goals>
<configuration>
<outputDirectory>${project.basedir}/src/gen/java</outputDirectory>
<classOrPackageName>org.example.*</classOrPackageName>
</configuration>
</execution>
In org.example there is a class called Mapper that has a Properties and Platform annotation with an included .hpp header and a target and global. For some reason when I run mvn clean install though, I get this:
[WARNING] No classes found in package org.example

You'll need to compile those classes with a call to maven-compiler-plugin before that.

Here are all the plugins in my pom.xml, which also includes the maven-compiler-plugin (still doesn't work)

No, I guess not. Like I said, try to do like with the presets.

I think I may have accidentally deleted the rest of my comment aside from the maven stuff. Yeah it still doesn't work (I actually did have the compiler-plugin before that as well) and also that is pretty much exactly like how the presets do it. I suppose I will take a look again a bit later but at the moment I have ran into another issue.
