No basedir set from native-maven-plugin - maven

Question

I'm having some trouble getting the maven native plugin to work. The problem is that I'm getting an IllegalStateException: "No basedir set" when compiling. The stacktrace follows:
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.codehaus.mojo:native-maven-plugin:1.0-alpha-7:compile (default-compile) on project native-ipc: Execution default-compile of goal org.codehaus.mojo:native-maven-plugin:1.0-alpha-7:compile failed: No basedir set

I feel like I'm missing something obvious. Any help would be appreciated.

If anyone else runs into this, the problem seemed to be tag order. Ad moved the original pom.xml into a macosx sub-module. The following maven file worked.
<?xml version="1.0" encoding="UTF-8"?>

<modelVersion>4.0.0</modelVersion>
<!-- #todo Break this out into a parent pom and child modules once we have multiple platforms to support. -->

Answer 2

The problem is caused by not having a <directory> defined inside a <source>. In the problem above, you have:
<sources>
...
<source>
<includes>
<include>/Library/Java/...</include>
<include>/Library/Java/...</include>
<includes>
<source>
...
<sources>
Notice there is no <directory> tag!
I had a similar problem where I was using a Maven property in the directory tag. Unfortunately, the Maven property was undefined. Yes, it took a while to chase that down.
I hope this helps.
