[Gradle] KeytoolException: Failed to read key creature from store

| 개요

 

keystore 정보는 ProjectSettings.asset 파일에 아래와 같이 저장된다. 

  AndroidKeystoreName: '{inproject}: Keystore/name.keystore'
  AndroidKeyaliasName: name
...중략...
  androidUseCustomKeystore: 1

하지만 비밀번호와 같은 정보는 별도로 저장되다보니
체크아웃을 새로 받을 때마다, keystore 세팅을 다시 해줘야했다.

Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.

See https://docs.gradle.org/6.1.1/userguide/command_line_interface.html#sec:command_line_warnings

ProjectSettings.asset 파일에는 androidUseCustomKeystore값은 1로 남아있는데,

alias나 비밀번호 같은 값이 날아가 버려서 위와 같은 에러가 발생한다.

            EditorGUI.BeginChangeCheck();

            __ks_pass = EditorGUILayout.PasswordField("--ks-pass", __ks_pass);
            __ks_key_alias = EditorGUILayout.PasswordField("--ks-key-alias", __ks_key_alias);
            __key_pass = EditorGUILayout.PasswordField("--key-pass", __key_pass);

            if (EditorGUI.EndChangeCheck())
            {
                settings.__ks_pass = Base64.Encode(__ks_pass);
                settings.__ks_key_alias = Base64.Encode(__ks_key_alias);
                settings.__key_pass = Base64.Encode(__key_pass);
                settings.Save();
            }
        }
    }

    static class BuildConfigsRegister
    {
        [SettingsProvider]
        public static SettingsProvider CreateCustomSettingsProvider()
          => new BuildConfigsProvider();
    }
}

CI 툴에서 파라미터로 전달해도 되지만, 

버전 관리 툴에서 관리되었으면 해서 UserSettings에 값을 저장할 수 있도록 하였다.
