解析 Xcode 9 生成的 Coverage 文件时 SonarQube SonarSwift 插件异常

Question

在尝试将覆盖率报告推送到 SonarQube 服务器时，使用 SonarQube > SonarSwift 插件时出现错误。 我使用 Xcode 命令行生成了报告：

xcodebuild test -enableCodeCoverage YES -scheme iOS_Template -workspace iOS_Template.xcworkspace -destination 'platform=iOS Simulator,name=iPhone X'

当我运行sonar-scanner 扫描代码并上传报告时，我收到以下错误：

 INFO: Parse coverage report

我检查了 Sonarswift 插件，它似乎不支持 XCode9+（我的 Xcode 版本是 Xcode 9.2）并且想知道它是否导致了异常

Answer 1

事实证明，通过添加一个命令来“生成”一个覆盖率报告文件以供 SonarSwift 加载来解决。 命令是xcrun llvm-cov show -instr-profile

Answer 2

看看这个SonarQube documentation 页面。您必须先翻译输出，然后再将其发送到 SonarQube：

xcodebuild -scheme <schemeName> -enableCodeCoverage YES -derivedDataPath . clean build test
xcrun llvm-cov show -instr-profile=Build/Intermediates/CodeCoverage/Coverage.profdata <path to instrumented executable> > <coverage report file>

同时检查您的 sonar.swift.coverage.reportPath 设置。该文档还包含一个示例项目的链接。
