xdebug not talking to Eclipse debugger - eclipse

Question

I'm trying to get Eclipse to talk to xdebug. From the xdebug log, it seems that xdebug is working correctly (i.e.: it's sending it's <init> and <response> messages), but Eclipse is not sending anything to xdebug (i.e.: no feature_set, feature_get, etc. commands like Netbeans).
Here's my setup:
Mac OS/X 10.7.5
Eclipse 4.2.1 "Juno"
PHP Development Tools (PDT) SDK Feature 3.1.1.201209101312
(Netbeans 7.1.2)
MAMP 2.1.1 running:
apache 2.2.22
PHP 5.4.4
the PHP executable being run is /Applications/MAMP/bin/php/php5.4.4/bin/php
the PHP config file being used is /Applications/MAMP/bin/php/php5.4.4/conf/php.ini
xdebug 2.2.0
The relevant lines from my php.ini are:
[xdebug]
zend_extension = "/Applications/MAMP/bin/php/php5.4.4/lib/php/extensions/no-debug-non-zts-20100525/xdebug.so"
xdebug.default_enable = on
xdebug.remote_enable = on
xdebug.remote_host = localhost
xdebug.remote_port = 9000
xdebug.remote_autostart = on
xdebug.remote_handler = "dbgp"
xdebug.remote_autostart = on
xdebug.remote_mode = "req"
xdebug.remote_connect_back = on
xdebug.remote_log = /tmp/xdebuglog.log
I can get Netbeans to connect to xdebug on port 9000 with session ID netbeans-xdebug with no problem. Note that when I start debugging, it opens a new window in my web browser with ?XDEBUG_SESSION_START=netbeans-xdebug appended to the URL of the PHP file I'm running.
Here is a snippet from the xdebug log when Netbeans tries to connect:

In Eclipse…
I created a new PHP Project in the workspace, using the default PHP settings, and created separate folders for source files and public resources. I changed nothing in the PHP Include Path step, but in the PHP Build Path, I clicked Link Source and linked /Applications/MAMP/htdocs/projectname with a projectname folder in my project.
I then set Eclipse preferences as follows:
In General -> Web Browser, I've set it to use an external web browser (Firefox).
In PHP -> Debug -> Installed Debuggers, I've checked that XDebug is in the list, is using port 9000, JIT remote sessions are off, and I used these instructions to ensure it uses the idekey mparker17.
In PHP -> Debug, I:
Set the PHP Debugger to "XDebug"
Set the PHP Server to the correct base URL (http://projectname.local) local web root (/Applications/MAMP/htdocs/projectname) and path mapping between the server and my workspace.
Set the PHP Executable to the correct executable path (/Applications/MAMP/bin/php/php5.4.4/bin/php), PHP ini file (/Applications/MAMP/bin/php/php5.4.4/conf/php.ini), the SAPI type to "CLI" and the PHP debugger to "XDebug".
Checked the Enable CLI Debug checkbox.
Checked the Break at first line checkbox.
In my debug configurations, I added a PHP Web Application and set it's preferences as follows:
In the Server tab I set the PHP server created above, set the file correctly, and set the URL correctly.
Here is a snippet from the xdebug log when Eclipse tries to connect:

This seems to indicate to me that Eclipse isn't talking to xdebug, but I'm stumped as to why that would be happening.

Answer 1

JIT remote sessions are off
Turn it on.
