ImageIO.write() not saving file

Question

The absolute file path seems to be forming correctly but the file is not being written.

Code:

var image = ImageIO.read(new ByteArrayInputStream(attachPageScreenshot()));
var saveDirectory = Paths.get("target", "screenshots").toAbsolutePath().toString();
var builder = new StringBuilder();
builder.append("\\").append(context.getDisplayName()).append(".png");
var filePath = saveDirectory.concat(builder.toString());
var saveFile = new File(filePath);
ImageIO.write(image, "png", saveFile);

Output:

java.io.FileNotFoundException: E:\workspace\java\selenium-junit5-starter\target\screenshots\Verify Total Interest Per Annum - Deposit = 30000, Term = 2 Years.png (The system cannot find the path specified)

Anything amiss?

Answer 1

I assumed Paths.get() automatically created the directory if it did not exist.

var dir = new File(saveDirectory);
if (!dir.exists()) {
    dir.mkdirs();
}
ImageIO.write(image, "png", saveFile);
