在需要分析的工程根目录生成 compile_commands.json, 注意需要全新编译。
xcodebuild clean
xcodebuild -workspace /Users/yxj/Desktop/Demo/Demo.xcworkspace -scheme Demo -configuration Release | xcpretty -r json-compilation-database --output ./compile_commands.json
clang tool 会 autoDetectFromSource 去找 compile_commands.json 理论上不需要额外参数
