Answer 1

I've been facing this issue for a long time

So I decided to automate the identification and the removal of corrupt jars

this is the util class I created for this purpose:

import java.io.File;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.jar.JarFile;

public class MavenFix {

    public static void main(String[] args) throws IOException {
        Files.walk(Paths.get("C:/data/.m2/repository"))
        .filter(file -> file.toString().endsWith("jar"))
        .forEach(path -> {
            try {
                System.out.print(".");
                new JarFile(path.toString(), true).getManifest();
            } catch (Exception e) {
                System.out.println();
                System.out.println(path + " - " + e.getMessage());
                try {
                    cleanAndDeleteDirectory(path.getParent().toFile());
                } catch (IOException e1) {
                    System.err.println(e1.getMessage());
                }
            }
        });
    }

    public static void cleanAndDeleteDirectory(File dir) throws IOException {
        File[] files = dir.listFiles();
        if (files != null && files.length > 0) {
            for (File aFile : files) {
                Files.delete(aFile.toPath());
            }
        }
        Files.delete(dir.toPath());
    }
}
