java.lang.NoSuchMethodException: play.core.server.NettyServer.mainDevHttpMode

[Nick Fitros]

Hello,

After I run activator clean and then tried to start the server again with activator run, i got the following:

I can't find what is going on. Has anyone had this error before? If you need more info please let me know.

It's a play framework app with java.

Thanks,

Nick

I'm seeing this too - did you figure this out?

[Nick Fitros]

Nop. Still nothing. I can't understand what is going wrong.

[Michael Chu]

Ugh. I cleaned ivy, cleaned everything, reverted all changes..

[Nick Fitros]

Did that solve the issue for you? I cleaned it all but i still got it..

[Michael Chu]

Nope, didn't work. I even checked out a fresh (from production) branch =/ 

I'm using sbt version 0.13.5 and play 2.3 (2.3.7 -> 2.3.10) - my PlayRun.class doesn't have mainDevHttpMode whereas the last play framework one does. Still confused as to what changed, so I'll keep investigating.

I just had this same error.
Was moving my app from one host to another, together with .ivy2 dir, then ran ./activator run, and this happened. Cleaned .ivy2 - no luck.
Then it occurred to me that I do not have neither fdescfs nor procfs mounted on this FreeBSD box, and openjdk8 requires it.
So I mounted them, and was able to start my app.

sudo mount -t fdescfs fdesc /dev/fd
sudo mount -t procfs proc /proc
sudo sh -c "echo 'fdesc /dev/fd fdescfs rw 0 0' >> /etc/fstab"
sudo sh -c "echo 'proc /proc procfs rw 0 0' >> /etc/fstab"

Correcting myself: I also disabled "ws.securesocial" %% "securesocial" % "master-SNAPSHOT" and that seems to be the real culprit.

[Nick Fitros]

I confirm that "ws.securesocial" caused the problem for me too.

Thanks for the help!

What changed then?

Secure social master was bumped to 3.0-M4 to support Play 2.4. 
Fix your Play 2.3.x by changing secure social from master-snapshot to  "ws.securesocial" %% "securesocial" % "3.0-M3"

3.0-M3 is the release that works with Play 2.3.x

[Michael Chu]

That makes sense =/ Great catch. Thanks all!
