I tried the following code:

import java.io.*;
import java.net.URI;
import java.net.URISyntaxException;
import java.nio.file.Paths;

public class demo {
    public static void main(String[] args) throws IOException, InterruptedException {
        try {
            System.out.println(Paths.get(new URI("C:\Windows")).toFile().getAbsolutePath());
        } catch (URISyntaxException e) {
            e.printStackTrace();
        }
    }
}

Exception in eclipse

java.net.URISyntaxException: Illegal character in opaque part at index 2: C:Windows
    at java.base/java.net.URI$Parser.fail(URI.java:2995)
    at java.base/java.net.URI$Parser.checkChars(URI.java:3166)

I’m trying to make a gradle plugin that contains this piece of code.

I execute it in Gradle and he works, why does he get this exception in Eclipse?
