前奏

我正在为我的应用程序的 CI 使用 App Center，并使用默认的“推送挂钩”，每次推送到分支时都会重新构建。我的任务是将 API 端点作为 App Center 变量传递，该变量在 Build Configurations 中配置。

此外，我还有我的appcenter-pre-build.sh 脚本，它与.xcworkspace 文件位于同一目录中（如official documentation 中所述）。脚本本身如下所示：

#!/usr/bin/env bash

echo "EXECUTING APPCENTER_PRE_BUILD SCRIPT"

if [ -z "$VERSION_CODE_SHIFT" ]
then
    echo "You need define the VERSION_CODE_SHIFT variable in App Center"
    exit
fi

if [ -z "$ENDPOINT" ]
then
    echo "You need define the ENDPOINT variable in App Center"
    exit
fi

PLIST_PATH="VideoApp/VideoApp/Info.plist"

VERSION_CODE=$((VERSION_CODE_SHIFT + APPCENTER_BUILD_ID))

APP_CENTER_CURRENT_PLATFORM="ios"

if [ "$APP_CENTER_CURRENT_PLATFORM" == "ios" ]
then
    plutil -replace CFBundleVersion -string "$VERSION_CODE" $PLIST_PATH
    echo "Updated version code in $PLIST_PATH to new value: $VERSION_CODE"
    plutil -replace CFBundleShortVersionString -string "\${MARKETING_VERSION}.$VERSION_CODE" $PLIST_PATH
    echo "Updated marketing version in $PLIST_PATH to new value: \${MARKETING_VERSION}.$VERSION_CODE"
    plutil -replace HubEndpoint -string "$ENDPOINT" $PLIST_PATH
    echo "Updated HubEndpoint in $PLIST_PATH to new value: $ENDPOINT"
fi

所以，基本上，我从 App Center 中提取环境变量并修改我的 Info.plist，然后在代码中使用它的属性来设置 API 端点。此外，如您所见，应用程序的版本正在以类似的方式进行修改。

问题

App Center 构建最终失败并出现以下错误：

所以它以某种方式产生了这个脚本的副本。

这对我来说似乎很奇怪，因为脚本没有分配给任何目标，而是在 Xcode 之外创建的。

【解决方案1】：

我猜，问题出在某种脚本缓存上。我已从存储库中删除 appcenter-pre-build.sh，推送并在 App Center 中构建（这次没有错误），然后再次添加脚本，推送并且它正常工作。
