I have scoured this site, and been looking over solutions on how to fix this, and none have given a solution that changes the error occurring. I cannot pinpoint what the problem is. None of the similar questions regarding this have helped.
I'll start with the code I have
public static BufferedImage getImage(String uri) throws IOException {
BufferedImage image = null;
image = ImageIO.read(ImageLoader.class.getResource(uri));
return image;
}
And where I call the method
try {
sprite = ImageLoader.getImage("images/testSprite.png");
} catch (IOException e) {
e.printStackTrace();
}
The error returned is IllegalArgumentException input == null on the ImageIo.read line in the original method.
To preface, I have tried every imaginable file naming sequence. I tried it including res, the name of my resource folder (both with and without a slash at the beginning), I tried it with a slash preceding images, the folder that contains the image I'm trying to access, and simply the name of the image, again, with and without the slash.
I used Eclipse's "Build Path" to create my res folder in the Project folder, but if I look at the .zip, it doesn't contain the folders I included, even the src folder, but it does contain all of the class files from the src folder. I'm confused why this is happening.
I would really like some insight on what exactly I am doing wrong here.
EDIT: After trying nearly everything imaginable, I finally figured it out. The folder needs to be created as a Package, and the image needs to be placed within the package. A source folder or normal folder doesn't seem to be picked up by the compiler. Just add a package to your source folder for the image to be loaded.
