(tip : use -? to get the commmand line parameters)

There is a missing resource in your install.xml file.

D:\trail\simple\install.xml:49: Resource not found: .\Readme.txt 

Provide this file or remove it from install.xml file.

MY guess is that that your install.xml contains a InfoPanel reference like:

  <panels>
    <panel classname="InfoPanel" />
    ...
  </panels>

and a resourcedef like:

<resources>
  <res id="HTMLInfoPanel.info" src="Readme.txt" />
  ...
</resources>

which actually is referencing the missing "Readme.txt" file which will be shown in the info panel.

You should create this file or move it to the D:\trail\simple directory.
