I am using the following settings and it's not formatting .cls apex class files and giving the error "Couldn't resolve parser "apex""

Parser of type apex does not exist. Here is a .prettierrc we are using which formats the apex files just fine.

{
  "trailingComma": "none",
  "singleQuote": true,
  "tabWidth": 4,
  "printWidth": 150,
  "plugins": [
    "prettier-plugin-apex",
    "@prettier/plugin-xml"
  ],
  "overrides": [
    {
      "files": "**/lwc/**/*.html",
      "options": {
        "parser": "lwc"
      }
    },
    {
      "files": "*.{cmp,page,component}",
      "options": {
        "parser": "html"
      }
    }
  ]
}

with this part of package.json

"devDependencies": {
    "@prettier/plugin-xml": "^3.4.1",
    "prettier": "^3.3.3",
    "prettier-plugin-apex": "^2.1.4"
  },

hi @test01bodacious

I'm a DevOps manager for my company, we use prettier and salesforce.

For your usecase, i think you have to change your package.json to:

{
  "name": "<name>",
  "version": "1.0.0",
  "author": "<Email>",
  "devDependencies": {
    "@prettier/plugin-xml": "^3.4.1",
    "prettier": "^3.4.2",
    "prettier-plugin-apex": "^2.2.2"
  },
  "repository": {
    "type": "http",
    "url": "....."
  },
  "scripts": {
    "prettier": "prettier"
  },
  "dependencies": {
    "sfdx-plugin-source-read": "^1.4.0"
  }
}

I suggest to you to use the sfdx-plugin-source-read to retrieve easy and correct Profile

After the package.json update, execute in terminal:

npm install -y

to apply changes

and change the .prettierrc to:

{
	"plugins": ["prettier-plugin-apex", "@prettier/plugin-xml"],
	"printWidth": 600,
	"singleQuote": true,
	"trailingComma": "all",
	"bracketSpacing": false,
	"useTabs": true,
	"bracketSameLine": true,
	"apexInsertFinalNewline": false,
	"overrides": [
		{
			"files": "*.{trigger,cls}",
			"options": {"parser": "apex"}
		},
		{
			"files": "*.{apex}",
			"options": {"parser": "apex-anonymous"}
		},
		{
			"files": "**/lwc/**/*.html",
			"options": {"parser": "lwc"}
		},
		{
			"files": "*.{cmp,page,component,evt}",
			"options": {
				"parser": "html",
				"trailingComma": "none"
			}
		},
		{
			"files": "**/aura/**/*.js",
			"options": {"trailingComma": "none"}
		},
		{
			"files": "**/aura/**/*.{auradoc,design,app}",
			"options": {"parser": "angular"}
		},
		{
			"files": "**/*.xml",
			"options": {
				"parser": "xml",
				"useTabs": false,
				"tabWidth": 4,
				"xmlWhitespaceSensitivity": "preserve",
				"embeddedLanguageFormatting": "off",
				"xmlSelfClosingSpace": false
			}
		}
	]
}

Note the 1° Line:

! "plugins": ["prettier-plugin-apex", "@prettier/plugin-xml"]

Than should work 😁

Tell me if work

It's not even related to the XML plugin and should be closed.
