Header file not generated, build fails

[Aaron Riekenberg]

I'm trying to use hawtjni 1.8 for the first time to run the simple "printf" example from the documentation.

I've made a "Simple" java class as shown in the documentation (attached).  I've also attached my pom.xml.

It appears the maven-hawtjni-plugin is generating native files based on my maven artifact id (test).  Several files get generated and the plugin tries to compile them with gcc.  This fails because some files include a "test.h" that didn't get generated.

I've tried changing my maven artifactId in my pom.xml.  This changes the name of the not-generated header file that .c files expect, but the results are the same.

Am I missing something obvious?

Output from mvn clean install:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

SLF4J: Defaulting to no-operation (NOP) logger implementation

SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

[Hiram Chirino]

Just create 'src/main/native-package/src/test.h' file. It can be
empty if you whish, but if you want to avoid C compiler warnings
errors, your probably need to '#include <stdio.h>' for that printf
function def.
