xmlbeans-maven-plugin not finding javac - maven

Question

I am trying to setup xmlbeans-maven-plugin 2.3.3 in my Eclipse and while everything seems to go OK, It fails with an java.io.IOException due to inability to find the file C:\Users\Daniel\Workspace\MyProject\javac.
This is strange because javac is on the system's %PATH% so why would it try to find it in %PROJECT_LOC%?
I found this problem description which sounds very similar to mine, but I placed the JDK path in front of all other paths and that didn't help.
Any idea how to tell the xmlbeans-maven-plugin where to look for javac?
UPDATE 1: I tried working around this problem by simply copying javac.exe to the project's directory and at least it now finds it but the problem moved forward to:
java.lang.NoClassDefFoundError: com/sun/tools/javac/Main
Caused by: java.lang.ClassNotFoundException: com.sun.tools.javac.Main
at java.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
Exception in thread "main" Could not find the main class: com.sun.tools.javac.Main. Program will exit.
Any insight that could help come up with the correct solution to this (e.g. something in .m2/settings.xml?) would be appreciated.
UPDATE 2: I also tried this little solution I found in my searches:
<settings xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/settings-1.0.0.xsd">
<localRepository>c:\maven\repository</localRepository>
<configuration>
<compiler>C:\Program Files (x86)\Java\jdk1.6.0_37\bin\javac.exe</compiler>
</configuration>
</settings>
But that didn't help the plugin find javac. It still complains about "The system cannot find the file specified" for javac.exe.

Answer 1

Found the solution! In the project's pom.xml, simply add the following inside <configuration>:
<compiler>C:\Program Files (x86)\Java\jdk1.6.0_37\bin\javac.exe</compiler>
i.e.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>xmlbeans-maven-plugin</artifactId>
<version>2.3.3</version>
<executions>
<execution>
<goals>
<goal>xmlbeans</goal>
</goals>
</execution>
</executions>
<inherited>true</inherited>
<configuration>
<schemaDirectory>${basedir}/src/main/xsd</schemaDirectory>
<compiler>C:\Program Files (x86)\Java\jdk1.6.0_37\bin\javac.exe</compiler>
</configuration>
</plugin>
Also, be sure to point the Window -> Preferences -> Java -> installed JREs to the JDK's, not JRE's: C:\Program Files (x86)\Java\jdk1.6.0_37. As described in this thread.
