fs.append causes a conflict

[evil-shrike]

If a generator copies a file and then tries to add more content into it there will be a conflict

this.fs.copyTpl(this.templatePath('_appsettings.json.properties'), 'appsettings.json.properties', this);

// later 
this.fs.append('appsettings.json.properties', 'DATA_SOURCE=db');

User will be prompted:

 conflict appsettings.json.properties
? Overwrite appsettings.json.properties? overwrite
    force appsettings.json.properties

It's completely misleading as actually there's no any conflict. The file didn't exist before the run. It's just adding more content in the same session.

I'm running into this same problem. I'm trying to clone a repository, and then append some values from the generator options.

My workaround, for now, is to use spawnCommand to run the git clone, read the contents of the file I want to append to, use spawnCommand to delete it, and then then this.fs.write to write the file with added values. Oddly enough if I use this.fs.delete, it still throws the conflict.

Here is my solution. I try to read again and concat the content, and finally write all over again.

      const originalContent = fs.readFileSync(this.destinationPath('', 'src/content.js'), 'utf8');
      const toAppendContent = this.fs.read(this.templatePath('add_content'), 'utf8')
      fs.writeFile(this.destinationPath('', 'src/content.js'), originalContent.concat(toAppendContent), function (err) {
        if (err) return console.log(err);
      });
