Can I get properties defined in "gradle.properties" in JAVA STATEMENT?

Question

I defined a property in gradle.properties file like below:

user.password=mypassword

Can I use it as a variable value in my java statement?

Solution 1

Yes you can, however this is not a good idea nor a good practice. gradle.properties file is meant to keep gradle's properties itself, e.g. JVM args used at build time.

If you need to store user/pass pair in properties file, it should be placed under src/main/resources or other appropriate folder and separate from gradle.properties.

Side note: Not sure if keeping properties file in mobile application is safe in general.

Solution 2

You would have to read the properties file and extract the property first.

Properties prop = new Properties();
InputStream input = null;

try {

    input = new FileInputStream("gradle.properties");

    // load a properties file
    prop.load(input);

    // get the property value and print it out
    System.out.println(prop.getProperty("user.password"));
} catch (IOException ex) {
    ex.printStackTrace();
}

but my Config file need to store access key id and secret key. Where Config.Java have only string and integers to fetech the values through the app, but access key id and secretkey have use in Config file to create Authenticate Object. I have warning from Google Play Developer Console as it open to view, it may misuse.

WRONG! Private keys, passwords and personal data MUST be in gradle.properties

If user/pass is present in resources, it needs to be shipped to customers. Ideally, they should be in gradle.properties only which is not shipped. If someone wants to use it, they would need to add the required user/pass in their own gradle.properties. AFAIK, that is the right approach

Wouldn't the gradle.properties file cease to exist in a compiled application?
