Flutter - 解决混合开发iOS脚本打包遇到的问题

使用 Xcode 手动打包是正常的，但是使用脚本打包会报错，错误如下：

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

定位错误

到 Flutter 环境目录下，按图上所示地址找到 xcode_backend.sh，也可以直接看 官方脚本链接

  # 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

解决方案

可以看到，官方脚本的说明里面给出两个解决方案

方案一：直接设置 FLUTTER_BUILD_MODE 为 release

方案二：先运行 flutter build ios --release ，再使用 Xcode 去打包

这里我们是用 Jenkins 脚本进行打包，所以方案二不适用，方案一更加方便些

# 设置Flutter的编译模式为release
export FLUTTER_BUILD_MODE=release

# 执行原有项目的打包脚本
./script/build_iOS.sh
