Re: [Joda-money-interest] Compilation won't work on Macs

Hi Stephen,

I can appreciate your reluctance to fiddle with Maven.  In this case I think things are pretty straightforward, however.  You've already got:

          <source>1.5</source>
          <target>1.5</target>

in your pom.xml, which gets you almost there.  This isn't completely correct if your default JDK is not 1.5.  In that case, adding:

<compilerArgument>-verbose -bootclasspath ${java.home}\lib\rt.jar</compilerArgument>

Would complete the picture (with true cross-compilation to Java 1.5 when java.home points to JDK 1.5).  Just out of interest, I compared the classes produced from JDK1.5 and 1.6 (on Windows) and the bytecode is identical even without the extra compilerArgument.

Alternatively, you might like to check this out: http://maven.apache.org/plugins/maven-compiler-plugin/examples/compile-using-different-jdk.html as this identifies another approach for solving the issue.

Hope that's at least of some interest.

Cheers,

Rob
