windows dexdump failure

This is frustrating because it should be such a trivial thing. I don't know what the fix is. I was hopeful that the binary attached to Android Issue 14746 would fix me up but that didn't work out.

simple dx / dexdump on Mac

In Windows, I was getting a silly-stupid message from dx and then an error from dexdump so I wanted to try a dx / dexdump on Mac for a comparison. I picked a random JAR file.

[jjohnson@jjohnson 20110613]$ cp ~/.m2/repository/commons-lang/commons-lang/2.4/commons-lang-2.4.jar .
[jjohnson@jjohnson 20110613]$ dx --dex --output=test.apk commons-lang-2.4.jar
[jjohnson@jjohnson 20110613]$ dexdump -d -l xml test.apk

<package name="org.apache.commons.lang"
<class name="ArrayUtils"

Good enough. Easy peasy.

That's for real - did you see that in the previous output? That's the whole error message. Neat. So you can't use relative paths and you can't use an absolute path with a space? Perhaps Windows users already know what to really do but I'm just trying to be a good citizen and test a defect fix on Windows without tons of recent Windows experience.
