When I compile a simple code that has the following 2 import statements:

import javax.mail.*

import javax.mail.internet.*

I get the following message:

package javax.mail does not exist

package javax.mail.internet does not exist

Why do I get this error?

Here is the code I have:

import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;

class tester {
 public static void main(String args[]) {
   Properties props = new Properties();
   props.put("mail.smtp.com" , "smtp.gmail.com");
   Session session  = Session.getDefaultInstance( props , null);
   String to = "me@gmail.com";
   String from = "from@gmail.com";
   String subject = "Testing...";
   Message msg = new MimeMessage(session);
    try {
      msg.setFrom(new InternetAddress(from));
      msg.setRecipient(Message.RecipientType.TO , new InternetAddress(to));
      msg.setSubject(subject);
      msg.setText("Working fine..!");
    }  catch(Exception exc) {
       }
 }
}

For anyone still looking to use the aforementioned IMAP library but need to use gradle, simply add this line to your modules gradle file (not the main gradle file)

compile group: 'javax.mail', name: 'mail', version: '1.4.1'

The links to download the .jar file were dead for me, so had to go with an alternate route.

Hope this helps :)

You need the javax.mail.jar library. Download it from the https://www.oracle.com/java/technologies/javamail-releases.html and add it to your Eclipse project:

If you are using <module-info.java> then,

  1. Right-click on Project, go to Build Path -> Configure Build Path -> Libraries -> ModulePath -> Add External Jars.
  2. Browse to the javax.mail.jar file
  3. Click "Apply and Close".

Under module-info.java, add this:

module TestApp {
    **requires mail;**
}

you have to set the classpath of your mail.jar and activation.jar file like that:

open the command prompt:

c:\user>set classpath=%classpath%;d:\jarfiles\mail.jar;d:\jarfiles\activation.jar;.;

and if u don't have the both file then please download them here

Had the same issue. Obviously these .jars were included with Java <= v8.x out of the box, but are not anymore. Thus one has to separately download them and place them in the appropriate classpath as highlighted by several folks above. I understand that the new Java is modularized and thus potentially more light-weight (which is certainly a good thing, since the old setup was a monster). On the other hand this - as we can see - breaks lots of old build setups. Since the time to fix these isn't chargeable to Oracle I guess this made their decision easy...
