Hi,
I am getting the following error while trying to run shindig in the debug
mode
The projects in the reactor contain a cyclic reference: Edge between
'Vertex{label='org.apache.shindig:shindig-gadgets'}' and
'Vertex{label='org.apache.shindig:shindig-gadgets'}' introduces to cycle in
the graph org.apache.shindig:shindig-gadgets -->
org.apache.shindig:shindig-gadgets
I am giving -Prun as the mvn argument in the External Tools.
I am following the steps outlined below from Chris's article : this use to
run with earlier version of shindig before -Prun came into picture :-(
*Creating run and debug profiles in Eclipse *
Running Shindig out of the box is possible by using the included Jetty
server <http://www.mortbay.org/jetty-6/>. Maven can start Jetty directly
with the command, "mvn jetty:run" or "mvn jetty:run-war". These would be
executed in the <shindig_home>/java directory. Shindig however now uses a
higher level "mvn -Prun" which also starts Jetty as well but it is launched
directly from the <shindig_home> directory. In order to run Shindig from
Eclipse, you can set up run and debug profiles within Eclipse that execute
this same high level mvn command ("mvn -Prun").
To create an external tools run profile to execute the command "mvn -Prun",
do the following:
(Running Jetty from mvn steps adapted from:
http://cwiki.apache.org/WICKET/maven-jetty-plugin.html )
1. In eclipse, from the main menu, select: "Run --> External Tools -->
Open External Tools Dialog..."
2. In the upper left hand corner of the dialog click on the icon for "New
launch configuration".
3. You can name this configuration something like: "mvn_run".
4. On the "Main" tab, fill in the "Location:" as the full path to your
"mvn" executable.
For example: /usr/local/apache-maven/apache-maven-2.0.8/bin/mvn
5. Edit the "Working Directory:" field. Select the workspace and project
that matches your Shindig project. Ex: ${workspace_loc:/shindig-all}
6. For Arguments: add "-Prun" (without quotes).
7. In the same dialog, now click on the "Environment" tab.
8. Add these two variables with values:
JAVA_HOME
{ path to parent of your Java bin directory. ex: /usr }
MAVEN_OPTS
-Xdebug -Xnoagent -Djava.compiler=NONE
-Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=y
9. Click Apply and Close.
You can now launch Shindig with a JPDA port of 4000.
To debug Shindig, you'll need to create a Debug profile.
This step allows you to launch your Shindig project in debug mode and attach
to Jetty.
1. In Eclipse, form the main menu, select "Run --> Open Debug Dialog..."
2. In the dialog, select "Remote Java Application".
3. Click on the icon for "New launch configuration".
4. Feel free to name this configuration, "shindig_debug".
5. For the "Project:", select your shindig server project that you
created earlier. (ex: shindig-all).
6. Under the "Connection Properties" set the port to 4000, which is the
same "address=" port specified in your Jetty run configuration above.
7. Click Apply and Close.
8. That's it, you can now run Shindig from Eclipse!
