使用 Xcode 手動打包是正常的，但是使用腳本打包會報錯，錯誤如下：

The following build commands failed:
    PhaseScriptExecution [CP-User]\ Run\ Flutter\ Build\ Script .../Script-C3A097A8FE12FF5F875B057C.sh
    
flutter build ios --release
then re-run Archive from Xcode.
Command PhaseScriptExecution failed with a nonzero exit code

定位錯誤

到 Flutter 環(huán)境目錄下，按圖上所示地址找到 xcode_backend.sh，也可以直接看 官方腳本鏈接

  # Archive builds (ACTION=install) should always run in release mode.
  if [[ "$ACTION" == "install" && "$build_mode" != "release" ]]; then
    EchoError "========================================================================"
    EchoError "ERROR: Flutter archive builds must be run in Release mode."
    EchoError ""
    EchoError "To correct, ensure FLUTTER_BUILD_MODE is set to release or run:"
    EchoError "flutter build ios --release"
    EchoError ""
    EchoError "then re-run Archive from Xcode."
    EchoError "========================================================================"
    exit -1
  fi

解決方案

可以看到，官方腳本的說明里面給出兩個解決方案

方案一：直接設置 FLUTTER_BUILD_MODE 為 release

方案二：先運行 flutter build ios --release ，再使用 Xcode 去打包

這里我們是用 Jenkins 腳本進行打包，所以方案二不適用，方案一更加方便些

# 設置Flutter的編譯模式為release
export FLUTTER_BUILD_MODE=release

# 執(zhí)行原有項目的打包腳本
./script/build_iOS.sh
