There is no formatter for 'java' files Installed

[overfullstack]

Getting this pop-up when trying to format Java files

• VS Code version: 1.81.0-insider
• Gradle version: 8.2.1
• Java version: 17.0.5
• Gradle for Java extension: v3.12.7

Spotless Settings in VS Code:

"java.format.enabled": false,
"files.trimTrailingWhitespace": false,
"spotlessGradle.diagnostics.enable": true,
"spotlessGradle.format.enable": true,
"editor.codeActionsOnSave": {
  "source.fixAll.spotlessGradle": true
},
"[java]": {
  "editor.defaultFormatter": "richardwillis.vscode-spotless-gradle"
},
"[kotlin]": {
  "editor.defaultFormatter": "richardwillis.vscode-spotless-gradle"
},
"[kotlinGradle]": {
  "editor.defaultFormatter": "richardwillis.vscode-spotless-gradle"
}

Sample Project: https://github.com/overfullstack/ds-algo
Spotless Config: https://github.com/overfullstack/ds-algo/blob/master/buildSrc/src/main/kotlin/ds-algo.root-conventions.gradle.kts#L26

spotless {
  lineEndings = PLATFORM_NATIVE
  kotlin {
    ktfmt().googleStyle()
    target("**/*.kt")
    trimTrailingWhitespace()
    endWithNewline()
    targetExclude("**/build/**", "**/.gradle/**", "**/generated/**")
  }
  kotlinGradle {
    ktfmt().googleStyle()
    target("**/*.gradle.kts")
    trimTrailingWhitespace()
    endWithNewline()
    targetExclude("**/build/**", "**/.gradle/**", "**/generated/**")
  }
  java {
    toggleOffOn()
    target("**/*.java")
    importOrder()
    removeUnusedImports()
    googleJavaFormat()
    trimTrailingWhitespace()
    indentWithSpaces(2)
    endWithNewline()
    targetExclude("**/build/**", "**/.gradle/**", "**/generated/**")
  }
  format("xml") {
    targetExclude("pom.xml")
    target("*.xml")
    eclipseWtp(XML)
  }
  format("documentation") {
    target("*.md", "*.adoc")
    trimTrailingWhitespace()
    indentWithSpaces(2)
    endWithNewline()
  }
}

This has a mix of both Kotlin and Java

• ./gradlew spotlessDiagnose --no-configuration-cache succeeds and Spotless is setup correctly as ./gradlew spotlessApply works as expected

@badsyntax Would you be able to check this? If you're occupied, could you guide me to setup this locally & try fixing it?

Similar issue for me, wehn I try to format Java sources with "richardwillis.vscode-spotless-gradle" I receive error:

Extension 'Spotless Gradle' is configured as formatter but it cannot format 'Java'-files

My config:

"[java]": {
        "editor.defaultFormatter": "richardwillis.vscode-spotless-gradle",
        "spotlessGradle.format.enable": true,
        "spotlessGradle.diagnostics.enable": true,
        "editor.codeActionsOnSave": {
          "source.fixAll.spotlessGradle": "always"
        }
    },
    "[gradle]": {
      "editor.defaultFormatter": "richardwillis.vscode-spotless-gradle",
      "spotlessGradle.diagnostics.enable": true,
      "spotlessGradle.format.enable": true
    },
    ...

Command line ./gradlew spotlessApply works fine

I had multiple gradle versions installed on my machine, when I faced this issue. I removed all except one version, the issue is gone. Not sure why that's a problem.

I used sdkman to install multiple versions.
