Connecting to my MongoDB Database
Hello everyone,
I am struggling to find the reason why I cant connect with my database on MongoDB. This is my first project on java ever and it is going to be an App. I think I have the wrong line of code for the connection I intended to use on MongoDB and I kinda got confused with all the Methods. I am using VS Code and I think using the MongoDB extension on VS is the most practical going forward. So if anyone has some experience working with these tools I would appreciate the help. When trying to run the server this is the error message iI get
querySrv ENOTFOUND _mongodb._tcp.cluster0.mongodb.net and this is the line on my .env i am using to connect to MongoDB MONGO_URI=mongodb+srv://mmetinbirguel:[email protected]/Tierlist?retryWrites=true&w=majority
Of course I have my real password instead of just "password" there, for safety reasons I share it like this 😄

Eclipse MAT - Remove Self-Referential Inbounds
I'm trying to track down a memory leak, and I can't figure out how to find what's retaining the object. Many of the object's members hold references to it, so the inbounds view is clogged up by those items that will get freed with the object.
Doing "shortest path to GC root" zooms out to the massive top level of the classloader itself, making me dig all the way down to find the object in question.
Does anyone know how to filter the inbounds of an object to just those that wouldn't get disposed with said object?...

Looking for Tips, Advice and Resources for Project Management with Java and Gradle
Hi, I am new to java and gradle and want to make a project larger than a simple hello-world or calculator app. I am not using any IDEs at the moment because I am interested in learning CLIs and how stuff might need to be set up manually. I know its probably dumb and I'd almost never have to do it, I just want to for learning purposes.
That being said, what would the best way be to add additional java files and classes in a typical gradle project? Should I be adding classes under
/app/src/main/java/project-name? Should I be manually making .java files in the main and test folders? Or is there a gradle command that can template this out?
I apologize for my noobliness. As the title suggests, anything related to project management would be appreciated! And sorry I am not looking to use Intellij or Eclipse or an IDE for this project, however I am open to in the future. Thanks in advance!...Program Randomly Quitting After Font.createFont() statement

Maven Archetype Catalog
Having some trouble getting a remote archetype catalog created. I figure it could be automatically managed by maven when I push an archetype but there doesnt seem to be good documentation around it.
I'm using AWS CodeArtifact as my remote repo, which means I need to have all files inside a package, where the docs outline the
archetype-catalog.xmlshould be at the root of the repo
