I am producing android project through apache ant. after android update project command. I put ant release during my root directory from the project. It states

"C:Program FilesAndroidandroid-sdktoolsantmain_rules.xml:384: Compile unsuccessful begin to see the compiler error output for particulars."

  1. Where will i see compiler output ?
  2. What type of error this ought to be because same project I'm able to build through eclipse and sign application?

Where will i see compiler output ?

Theoretically, it will likely be inside your Command Prompt window, in which you went the ant release command, and above in which you begin to see the "C:Program FilesAndroidandroid-sdktoolsantmain_rules.xml:384: Compile unsuccessful begin to see the compiler error output for particulars.".

What type of error this ought to be because same project I'm able to build through eclipse and sign application?

That's impossible to reply to within the abstract, sorry.
