xcodebuild忽略-derivedDataPath

Question

是我误解了-derivedDataPath的功能，还是这是一个bug？您可以在输出中清楚地看到，xcodebuild忽略了命令行值，默认为Library/Developer/Xcode/DerivedData。

Command line invocation:
/Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -project MyProj.xcodeproj -scheme “MyProj (iOS)" -destination "name=iPhone 12" -derivedDataPath=/Users/alpe77/myproj/MyProj/Build build

User defaults from command line:
    derivedDataPath = /Users/alpe77/myproj/MyProj/Build
    IDEPackageSupportUseBuiltinSCM = YES

我遇到了同样的问题(Xcode12.4)，并发现构建环境配置变量CONFIGURATION_BUILD_DIR覆盖了-derivedDataPath中给出的路径

我打开"Xcode首选项>位置>派生数据>高级“，并将构建位置设置从我的自定义设置更改为”唯一“，这解决了问题。

感兴趣的是如何防止CONFIGURATION_BUILD_DIR在命令行上覆盖-derivedDataPath ...
