  --require               Will require a module before running the gulpfile.  
                          This is useful for transpilers but also has other

  --gulpfile, -f          Manually set path of gulpfile. Useful if you have  
                          multiple gulpfiles. This will set the CWD to the  
                          gulpfile directory as well.                   [string]  
  --cwd                   Manually set the CWD. The search for the gulpfile, as  
                          well as the relativity of all requires will be from  
                          here.                                         [string]  
  --verify                Will verify plugins referenced in project's  
                          package.json against the plugins blacklist.  
  --tasks, -T             Print the task dependency tree for the loaded  
                          gulpfile.                                    [boolean]  
  --tasks-simple          Print a plaintext list of tasks for the loaded  
                          gulpfile.                                    [boolean]  
  --tasks-json            Print the task dependency tree, in JSON format, for  
                          the loaded gulpfile.  
  --tasks-depth, --depth  Specify the depth of the task dependency tree.[number]  
  --compact-tasks         Reduce the output of task dependency tree by printing  
                          only top tasks and their child tasks.        [boolean]  
  --sort-tasks            Will sort top tasks of task dependency tree. [boolean]  
  --color                 Will force gulp and gulp plugins to display colors,  
                          even when no color support is detected.      [boolean]  
  --no-color              Will force gulp and gulp plugins to not display  
                          colors, even when color support is detected. [boolean]  
  --silent, -S            Suppress all gulp logging.                   [boolean]  
  --continue              Continue execution of tasks upon failure.    [boolean]  
  --series                Run tasks given on the CLI in series (the default is  
                          parallel).                                   [boolean]  
  --log-level, -L         Set the loglevel. -L for least verbose and -LLLL for  
                          most verbose. -LLL is default.                 [count]

Answer

Hi @john john ,
The files that gulp package-solution --ship looks for are created by first running gulp bundle --ship. Failure to run the bundle command prior to invoking package-solution will cause the package-solution command to fail, as shown in the pic.

Please check the file in D:\extensionForFullstack\extension-for-fullstack\src\extensions\helloWorld\HelloWorldApplicationCustomizer.manifest.json
