Maven搜索旧版本的Javax.Mail依赖项（1.4.3）虽然我有它的最新版本（1.6.1）并抛出ClasNotFoundException

我正在尝试在Cucumber testRunner类中编写一段代码，以便在执行后通过Email发送测试结果报告，但我遇到了这个我无法解决的问题。我添加了Javax.Mail库（版本1.6.1）的依赖项，并在testRunner中编写了以下方法，

@AfterClass
public static void teardown() throws UnknownHostException, IOException {       
    HTML_TestExecutionReportParser testExecutionStatusParser = new HTML_TestExecutionReportParser();
    sendTestExecutionReportEmail(testExecutionStatusParser.isAssertionFailureFound());    

}

public static void sendTestExecutionReportEmail(boolean testExecutionStatus) throws IOException {
    String mailSubject = null;
    String mailBody = null;     
    if (testExecutionStatus) {
        mailSubject = "Sub";
        mailBody = "body";
        sendEmail(mailSubject,mailBody);            
    }
    else {
        mailSubject = "Sub";
        mailBody = "body";          
        sendEmail(mailSubject,mailBody);
    }

}

public static void sendEmail(String mailSubject, String mailBody) throws IOException {
    Properties props = new Properties();
    Properties prop = new Properties();
    PropertyFileLoader propFileLoader = new PropertyFileLoader();
    prop = propFileLoader.loadPropertyFile("PropertyFiles", "EmailConfiguration.properties");
    props.put("mail.smtp.host", prop.getProperty("SMTPHostName"));
    props.put("mail.smtp.port", prop.getProperty("SMTPPort"));
    props.put("mail.smtp.ssl.trust", prop.getProperty("SMTPHostName"));
    final String EmailP = prop.getProperty("SMTPP");
    props.put("mail.smtp.starttls.enable", "true");
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.connectiontimeout", "10000");
    final String User = prop.getProperty("SMTPU");
    Configurations config = new Configurations();
    String reportFolderPath = "TestExecutionReports";
    String reportName = "report.html";

    try {
        Session session = Session.getInstance(props, new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(User, EmailP);
            }
        });

        InternetAddress fromAddress = new InternetAddress("email", "name");
        InternetAddress toAddress = new InternetAddress("email", "name");
        session.getProviders();
        session.setDebug(true);
        Message msg = new MimeMessage(session);
        msg.setFrom(fromAddress);
        msg.addRecipient(Message.RecipientType.TO, toAddress);
        msg.setSubject(mailSubject);
        Multipart multipart = new MimeMultipart();
        MimeBodyPart textBodyPart = new MimeBodyPart();
        textBodyPart.setText(mailBody);
        MimeBodyPart attachmentBodyPart = new MimeBodyPart();
        String attachmentName = config.getResourcePath(reportFolderPath) + reportName;
        DataSource source = new FileDataSource(attachmentName);
        attachmentBodyPart.setDataHandler(new DataHandler(source));
        attachmentBodyPart.setFileName("Report.html");
        multipart.addBodyPart(textBodyPart);
        msg.setContent(multipart);      
        Transport.send(msg);

    } catch (MessagingException e) {
        System.out.println(e.getMessage() + e.getStackTrace());
    } catch (UnsupportedEncodingException e) {
        System.out.println(e.getMessage());
    }
}

代码中没有显示错误，但是当我运行它时，它会在控制台中抛出以下错误，

DEBUG: setDebug: JavaMail version 1.4.3
DEBUG: getProvider() returning 
javax.mail.Provider[TRANSPORT,smtp,com.sun.mail.smtp.SMTPTransport,Sun 
Microsystems, Inc.,1.4.3]
java.lang.ClassNotFoundException: com.sun.mail.smtp.SMTPTransport
at java.net.URLClassLoader.findClass(URLClassLoader.java:381)

最初编写代码时，虽然我对POM.xml文件中提到的最新版本有依赖性，但我在Maven依赖项下找不到任何Javax.mail jar文件，但是代码没有显示任何错误。后来我设法通过Maven正确安装了Javax.mail库（版本1.6.1），但是当我运行测试时，上面的异常一直在抛出，从上面的控制台输出的第一行，我假设Maven是寻找旧版本的Javax.mail库，因为它不可用，它会抛出classNotFound异常。但我不确定如何将Maven指向Maven Dependencies下可用的最新Javax.mail库。

非常感谢任何帮助......！

您需要从javax.mail:mailapi排除io.rest-assured:json-schema-validator。

<dependency>
  <groupId>io.rest-assured</groupId>
  <artifactId>json-schema-validator</artifactId>
  <version>3.0.3</version>
  <scope>test</scope>
  <exclusions>
    <exclusion>
      <groupId>javax.mail</groupId>
      <artifactId>mailapi</artifactId>
    </exclusion>
  </exclusions> 
</dependency>

问题是您的pom.xml实际上包含两个Java Mail API工件：javax.mail:mailapi和javax.mail:javax.mail-api。从技术上讲，这是两个不同的工件，包括javax.mail-api，特定版本不会覆盖mailapi的版本。

无论如何mailapi似乎是无效的工件，可能是由某人错误地部署的。

您可能还想与json-schema-validator的开发人员联系，让他们知道他们使用了无效的mailapi工件。

例如，在IntelliJ的情况下，你就是IDLE。重新导入maven项目依赖项。

您可以通过点击“项目结构”＆gt;来实现此目的。 pom.xml＆gt;右键单击＆gt; Maven＆gt;重新导入。

这应该重新导入所有依赖项。如您所说，请确保在重新导入之前，您的pom.xml中提供了正确的版本。
