java.lang.NoSuchMethodError: com.sun.mail.imap.IMAPFolder.idle() about spring-integration-samples HOT 22 CLOSED

You seem to have an old version of com.sun.mail:imap on your classpath - try using a more recent version (e.g. 1.5.6).

from spring-integration-samples.

This also happens when you are using javax.mail standalone with spring-boot-starter-mail. com.sun.mail:imap uses javax.mail(v.1.5.6) internally. When you are using javax.mail version other than 1.5.6, you have 2 version of the IMAPFolder (one from com.sun.mail and other from javax.mail) in your dependency tree. Maven will resolve this conflict by choosing IMAPFolder from javax.mail which does not contain theidle() method. This causes the java.lang.NoSuchMethodError exception.


Solution
You can update the version of javax.mail to 1.5.6 to make it compliant with com.sun.mail:imap

from spring-integration-samples.

Hi Rohan,
Yes, we are using javax.mail standalone. https://mvnrepository.com/artifact/javax.mail/mail/1.4.7
Should I replace it with https://mvnrepository.com/artifact/com.sun.mail/javax.mail/1.5.6 ?

Thanks,
Pankaj

from spring-integration-samples.

No, replacement. You should declare like:

compile "javax.mail:javax.mail-api:1.5.6"
compile "com.sun.mail:javax.mail:1.5.6"
compile "com.sun.mail:imap:1.5.6"

from spring-integration-samples.

@pankajkh I had the same issue, so updating the version of javax.mail to 1.5.6 my pom.xml fixed this

from spring-integration-samples.

@artembilan : Can you please provide more detail ? How it will fix the issue.
@rohangulati : there is no version 1.5.6 to upgrade for jar (javax.mail:mail). I need to replace with other jar (com.sun.mail:javax.mail).

from spring-integration-samples.

@pankajkh You should use https://mvnrepository.com/artifact/javax.mail/javax.mail-api/1.5.6

from spring-integration-samples.

One more time:

javax.mail:javax.mail-api:1.5.6

not

javax.mail:javax.mail:1.5.6

The impl is in the com.sun.mail:javax.mail:1.5.6.

from spring-integration-samples.

Thanks a lot, got it now.

from spring-integration-samples.

Hi all
iam getting same error
javax.mail:javax.mail-api:1.5.6
here no like idle() in this api
{
javax.mail:javax.mail:1.5.6
here idle() method there
}
uisng this api

from spring-integration-samples.

can you give clarity which api i have to use to remove this error
Exception in thread "Thread-2" java.lang.NoSuchMethodError: com.sun.mail.imap.IMAPFolder.idle()V
at com.uralian.cgiats.EmailAccess$IdleThread.run(EmailAccess.java:267)

from spring-integration-samples.

You must still have an incompatible imap jar on the class path somehow. Run the jvm with -verbose to see which jar IMAPFolder is being loaded from.

from spring-integration-samples.

IMAPFolder class is only there in javax.mail:javax.mail:1.5.6
not in javax.mail:javax.mail-api:1.5.6

in run time it's not picking the idle() method it's there in IMAPFolder in javax.mail:javax.mail:1.5.6
where can i add to pick this jar

from spring-integration-samples.

As I said -verbose is your friend.

Or, perhaps you are running in an app server that has an old javamail.

from spring-integration-samples.

i am running this application as standalone by using this jar https://mvnrepository.com/artifact/javax.mail/javax.mail/1.6.0 this not web app

from spring-integration-samples.

What version of Spring Integration? 5.1.1 uses javamail 1.6.2 and works fine.

Show your complete POM.

from spring-integration-samples.

this is spring version
<spring.version>4.3.8.RELEASE</spring.version>

from spring-integration-samples.

I asked for spring-integration version.

from spring-integration-samples.

means i did't get you

from spring-integration-samples.

This is becoming tedious; as I said

Show your complete POM.

from spring-integration-samples.

we are not using spring integaration

from spring-integration-samples.

So why are you asking this question in a Spring Integration GitHub issue?
