我在这里添加了 repo 协议(protocol)。我已经使用示例代码来制作发布应用程序版本但无法生成它们。 keystore 已创建并添加到代码库中
最佳答案
对我来说这是一个路径问题。
我正在关注 flutter 指南 https://flutter.io/docs/deployment/android
Create a file named <app dir>/android/key.properties that contains a reference to your keystore:
出于某种原因,我(错误地)将我的“key.properties”放在了 app_dir/android/app 文件夹中,这给了我错误。

所以检查你的路径,以及你的文件所在的位置:)
奖金信息: 对 med 有帮助的是检查具有不同设置的“gradle.build”文件,而它总是给我带来问题的 storeFile 文件(keystoreProperties['storeFile'])。 尝试将其注释掉,或将其更改为:
storeFile file("key.jks")
如果这有效,您就知道您拥有“key.jks”文件的正确路径。然后尝试引入 poperties 文件(keystoreProperties) 喜欢
storeFile file(keystoreProperties['storeFile'])
一开始没有用,但现在可以了:)
因此请再次检查您的“key.jks”和“key.properties”文件是否位于“正确”位置,以及您如何指向它们。
