Assessment

Difficulty: 4/5
Estimated time: 3-5 days
Newbie friendliness: 25/100

Issue type: Bug
Clarity: Needs clarification
Activity status: Stale
Tech stack: java, kotlin
Domain: build-system, tooling

Research direction

Start with the root build.gradle.kts configuration and the :app:spotlessHtmlCheck task, then reproduce the failure with ./gradlew spotlessCheck. Investigate the reported NpmFormatterStepStateBase$ServerStartException and compare behavior between Spotless 7.0.2 and v6. Done means the configured HTML check runs reliably without the server-start failure.

Written by the indexing model from the issue text.

Description

bug

My CI has failed several times due to :app:spotlessHtmlCheck, even though it was fine a few minutes before. The HTML file was never modified for so long and it was so strange to suddenly fail.

Version: 7.0.2
This problem never happened in previous version (v6)

Root build.gradle.kts

format("html") {
  target("**/src/main/assets/**/*.html")
  targetExclude("${layout.buildDirectory}/**")
  prettier()
}

In CI, they're invoked with ./gradlew spotlessCheck
