View Full Version : Error executing page compilation Circular extends reference for class Sample.deadlock

16 Oct 2012, 11:20 PM
Hi everyone,

I'm trying to compile my Ext JS 4.1.1.a based application using 64-bit Linux OS.
Here's my application hierarchy(Maven based Java Web Application):

+ src
+ extjs
+ app
- app.js
- index.jsp
+ resources

It's a huge project, so I'd like to learn how can I find the classes that generates error. Here is the error stacktrace:

[ERROR] Circular extends reference :
Sample.deadlock.A ->
Sample.deadlock.B ->
Sample.deadlock.E ->
Sample.deadlock.C ->
Sample.deadlock.D ->
[ERROR] Error executing page compilation Circular extends reference for class Sample.deadlock.A
[ERROR] com.sencha.exceptions.ExCircularReference: Circular extends reference for class Sample.deadlock.A

Thanks in advance.

I got the same error using Sencha Cmd v3.0.0.250. Is there any update on this bug? I did not install Compass. Not sure if this would cause any problem. I am compiling ExtJS 4.1.0

I've provide an answer for this on StackOverflow (http://stackoverflow.com/questions/12929167/sencha-cmd-error-executing-page-compilation-circular-extends-reference-for-cla/14320132#14320132).

as always it helps to see that others have the same issues. Unfortunately I do not see a solution (also not on STackOverflow). Would be really great if someone would have the kindness to explain what the cause and the solution of the problem is. Since it seems to come from ExtJS any input from Sencha Experts would be greatly appreciated.
