Can you build native lib and Jar with a single pom.xml?
I have built a pom to build a native JNI library but the Java class that
sits on top of it is in a separate project. It makes running unit tests
a little tricky. I would like to move the Java code into the same
project and have the Jar and the library built with a single pom.
Is this possible? If so, how does one go about getting Maven to build
both a native library and a jar file?
Thanks,
Dave.

have you had a look at https://jna.dev.java.net
It makes calling native libraries a _lot_ easier

One solution (the hack way) is to have antrun call the required build steps
for you, or even just fork the native code build tool
Another solution is to refactor your maven projects, take the unit tests out
of that module and put them into a third module.
A = java
B = jni
C = unit tests of java
B depends on A
C depends on B & A

Normally you would separate out the piece that is depended on in two
places to a separate module to break the circle.

Okay.
Can you explain how one uses Maven to build jni libraries? Assume you
have a jar project containing the Java source file (i.e. main and test)
that provides the interface to the native code, and another project that
contains the native code, how do you build them?
Building the jar file requires the unit tests to run but they rely on
the native library but it can't be built because it relys on the Java
class in the jar file that is built from the Java project, but it can't
be built because it can't run unit tests that rely on the native code
from the native project but it can't be built....and on it goes. Chicken
and Egg problem.
How do you do this?
Dave.

The golden rule is one pom, one artifact.

Okay.
Can you explain how one uses Maven to build jni libraries? Assume you
have a jar project containing the Java source file (i.e. main and test)
that provides the interface to the native code, and another project that
contains the native code, how do you build them?
Building the jar file requires the unit tests to run but they rely on
the native library but it can't be built because it relys on the Java
class in the jar file that is built from the Java project, but it can't
be built because it can't run unit tests that rely on the native code
from the native project but it can't be built....and on it goes. Chicken

Hi
IIRC Freehep nar plugin (http://java.freehep.org/freehep-nar-plugin/)
generates a jar and a nar (native archive) in the same pom.
Bye
