adt error 301

Hi,

am new in this AIR thing nad I have following problem:
ip-89-103-132-47:~/Documents/projectAIR/AIRHelloWorld goddard$ adt -package -storetype pkcs12 -keystore src/air.pfx -keypass password -tsa none AIRHelloWorld.air src/HelloWorld.xml src/AIRHelloWorld.html src/AIRAliases.js
password: password
/Users/goddard/Documents/projectAIR/AIRHelloWorld/src/HelloWorld.xml: error 301: Application descriptor missing/cannot be opened

Based on this, I changed rights on app descriptor:
ip-89-103-132-47:~/Documents/projectAIR/AIRHelloWorld goddard$ ls -latr src
total 48
-r--r--r-- 1 goddard goddard 9710 Feb 9 01:16 AIRAliases.js
-rw-r--r-- 1 goddard goddard 278 Mar 22 17:44 AIRHelloWorld.html
-rw-r--r-- 1 goddard goddard 1714 Mar 29 01:26 air.pfx
-rwxrwxrwx 1 goddard goddard 368 Mar 29 02:15 HelloWorld.xml
drwxr-xr-x 6 goddard goddard 204 Mar 29 02:54 .
drwxr-xr-x 3 goddard goddard 102 Mar 29 02:56 ..

But nothing changed so far. My system is Mac OS X 10.4.11
Has anyone similar experience?
