Jenkins无法从链中的任何提供商加载AWS凭证

Question

我正在尝试在我的 SpringBoot 项目中使用AWS SES Simple Email Service发送电子邮件 知道我在AWS上验证了电子邮件，并且还创建了AWS_ACCESS_KEY和AWS_SECRET_KEY。

这是我的代码：

public static void amazonSimpleEmailService(String to, String subject, String htmlBody, String textBody) {

    AmazonSimpleEmailService client = AmazonSimpleEmailServiceClientBuilder.standard()
            .withCredentials(
                    new AWSStaticCredentialsProvider(new BasicAWSCredentials(AWS_ACCESS_KEY, AWS_SECRET_KEY)))

            .withRegion(Regions.EU_WEST_1).build();

    SendEmailRequest request = new SendEmailRequest().withDestination(new Destination().withToAddresses(to))

            .withMessage(new Message()
                    .withBody(new Body().withHtml(new Content().withCharset("UTF_8").withData(htmlBody))
                            .withText(new Content().withCharset("UTF-8").withData(textBody)))
                    .withSubject(new Content().withCharset("UTF-8").withData(subject)))
            .withSource(MAIL_ADMIN);
    client.sendEmail(request);

}

在 Jenkins （EC2实例）上构建代码时，会发生

Caused by: com.amazonaws.SdkClientException: Unable to load AWS credentials from any provider in the chain: [com.amazonaws.auth.EC2ContainerCredentialsProviderWrapper@55fe41ea: The requested metadata is not found at http://169.254.169.254/latest/meta-data/iam/security-credentials/, com.amazonaws.auth.profile.ProfileCredentialsProvider@2aceadd4: profile file cannot be null]

我怀疑缺少什么，但是我找不到它。
