我的项目正在生成coverage/.resultset.json，但coverage没有显示在sonar中。我正在使用simplecov 0.21.2，出现以下错误：

ERROR: Cannot read coverage report file, 
expecting standard SimpleCov JSON formatter output: 'coverage/.resultset.json'
java.lang.ClassCastException: class org.sonarsource.analyzer.commons.internal.json.simple.JSONObject cannot be cast to class org.sonarsource.analyzer.commons.internal.json.simple.JSONArray (org.sonarsource.analyzer.commons.internal.json.simple.JSONObject and org.sonarsource.analyzer.commons.internal.json.simple.JSONArray are in unnamed module of loader org.sonar.classloader.ClassRealm

simplecov文件具有以下设置：

require 'simplecov'
# features/support/env.rb
require 'simplecov'
# .simplecov
SimpleCov.start 'rails' do
  SimpleCov.formatters = SimpleCov::Formatter::MultiFormatter.new([
    SimpleCov::Formatter::HTMLFormatter,
    SimpleCov::Formatter::JSONFormatter
  ])
SimpleCov.start do
  enable_coverage :branch
end
  SimpleCov.minimum_coverage 70
end

sonar-project.properties：

sonar.projectKey=project
sonar.host.url=host
# --- optional properties ---
# authentication token to connect to sonar
sonar.login=token
# Path is relative to the sonar-project.properties file. Defaults to .
sonar.sources=.
sonar.ruby.coverage.reportPaths=coverage/.resultset.json
# Encoding of the source code. Default is default system encoding
sonar.sourceEncoding=UTF-8
