Root Cause

The keystore file specified in build.gradle for signing the release bundle does not exist at the given path.

build.gradle中指定的用于签署发布包的密钥库文件在给定路径下不存在。

Workarounds

  1. 90% success Verify the keystore path in android/app/build.gradle and ensure the file exists. Example: storeFile file('../keystores/release.jks') should point to an existing file. Move the keystore to the correct location or update the path.

Dead Ends

Common approaches that don't work:

  1. 95% fail

    The keystore path is hardcoded and cleaning the build does not create the keystore file.

  2. 85% fail

    The error is about the file path, not the password; password changes are irrelevant.

  3. 90% fail

    The keystore file is not inside the build folder; it's a separate file that must exist externally.
