Answer 1

Since I cannot see the keystore.properties file in your screenshot I assume you haven't created one?

You are trying to load the keystore.properties file but the file is missing. Therefore the property values are null, since no property file was loaded. To solve this problem you must create a file named keystore.properties in the projects root directory. The content of this file should contain your keystore credentials. This should look as follows:

keyStorePassword=storepw
keyAliasPassword=keypw
keyAlias=keyAlias
keyStore=/path/to/your/keystore-file.keystore
