This issue is on windows, As windows do not support POSIX file attributes. So a workaround is to remove file attributes or specify in windows manner. Just comment POSIX attributes lines in genrateTempFile function.

private File generateTempFile() {
try {
// final EnumSet attrs = EnumSet.of(OWNER_READ, OWNER_WRITE);
// final FileAttribute<?> attr = PosixFilePermissions.asFileAttribute(attrs);
final Path path = Files.createTempFile("multipartBody", "tempFile");
return path.toFile();
} catch (IOException e) {
throw new IllegalStateException(e);
}
}
