Invalid signature file digest for Manifest main attributes

[hencomb]

Java version: 8

Greetings,

We're trying out sendgrid/java for a corporate environment.

Message from one of our developers who is experiencing issues:

I’m not sure if the JAR is a problem, but since importing it into our application in order to send emails, we’re met with the following error:

java.lang.SecurityException: Invalid signature file digest for Manifest main attributes

I have downloaded the jar from this location:
https://github.com/sendgrid/sendgrid-java

And this is the code we’re trying to execute:

private static final String FROM = "noreply-ppppapp@pppppgroup.com";
private static final String SENDGRID_API_KEY = "API_KEY";

private void sendMessage(String toAddress, String subject, String text) {
    Content content = new Content("text/plain", text);
    Email from = new Email(FROM);
    Email to = new Email(toAddress);
    Mail mail = new Mail(from, subject, to, content);

    SendGrid sg = new SendGrid(SENDGRID_API_KEY);
    Request request = new Request();
    try {
        request.setMethod(Method.POST);
        request.setEndpoint("mail/send");
        request.setBody(mail.build());
        Response response = sg.api(request);
        System.out.println(response.getStatusCode());
        System.out.println(response.getBody());
        System.out.println(response.getHeaders());
    } catch (Exception ex) {
        log.error(ex.getMessage());
        ex.printStackTrace();
    }
}

It looks like when we get to the first line of the function:
Content content = new Content(“text/plain”, text)

Any pointers would be appreciated.

Hello @henrylcombrinck,

Just checking in to find out of you found success. Thanks!

thanks - my team member simply switched to simulating a CURL call using direct HTTP, instead of using the Java library (we needed a quick solution).
