Gradle shade not shading in one operating system, but does in another

The problem is that by somre reason, it does not shade what is otherwise being shade when I run the same command in my OS (windows) Does anyone have a clue what would be the case? I'm quite new to gradle, so that might be the cause. Here's part of the build script: ```kts shadowJar {...

How to access authenticated user/authentication object on react frontend after logging in?

I've set up a basic authentication flow using Spring Security 6 on my backend, with React handling the frontend for login, signup, and verification pages. It's all session cookie-based, no JWT, with sessions stored in Redis. Now, I'm wondering how I can handle things on the React side once a user logs in. How do I check if a user is logged in to restrict access to certain pages? I want to redirect them to the login page if they're not logged in or restrict page access based on their roles. Any tips on how to manage this? I also want to be able to get access to the authenticated user's details like their email, username, etc unless this isn't possible without implementing a /me endpoint on the backend that fetches the user details for me....

I cant figure out how to rename a file.

in order to delete from a file I first need to write everything that I don't want to delete into another file and then rename the the new file to the name of the old file. Then I would delete the old file. This is represented in the getDate() method. I am noticing that the new file (temp.txt) refuses to be renamed to the old file (savedata.txt). What should I do

Trying to implement CSRF protection with Spring Security and React frontend

I'm trying to get CSRF protection to work using spring security but I keep getting a 403 forbidden error when trying to make a post request to a csrf protected endpoint using postman. I followed the docs to the letter - this one to be specific with the only change being I replaced this line .addFilterAfter(new CsrfCookieFilter(), BasicAuthenticationFilter.class); with .addFilterAfter(new CsrfCookieFilter(), customUsernamePasswordAuthFilter.getClass()) as I have implemented a custom UsernamePasswordAuthenticationFilter to work with my frontend SPA built using react. On postman, there are two cookies present - SESSION and XSRF-TOKEN and I also include a X-XSRF-TOKEN header while making the post request and still get a forbidden error. I'm not currently sending any requests from the SPA directly. Just using postman for now....
