Invalid signature file digest for Manifest main attributes #631
Description
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.
