On my Mac computer, I follow the tutorial on this page to get the Taipan example run, but still failed so many times.
Switch to the Plug-in Development perspective and open the models folder within the org.eclipse.gmf.examples.taipan project. Explore each of the models found hereand their element properties. You'll notice that there are full and RCP versions of the generated Taipan examples to explore.
When I try to run as "Eclipse application", it launches a new eclipse app but the dialog box Examples does not have the 'Taipan Diagram' as it says:
create an empty project and a new 'TaiPan Diagram' found in the Examples folder of the New dialog
What are the possible causes? Someone helps me to solve it out?
I'm assuming that your plugin is working fine and doesnt show compilation errors?
Then the most likely reason is that you havent chosen your plugin to be active in your launch dialog.
I answered a similar question with this:
My guess is that you have just created the plugin, but aren't running it in your current Eclipse instance. That can be verified by opening the view "Plugin registry". That will show a list of all plugins, see if the plugin you have created is in that list.
If you click on the run button in Eclipse you will open a run configuration dialog. In one of the tabs, you get to choose what plugins should be available. Make sure your plug-in is selected. This will start up a new Eclipse instance that will run your plugin.
To make your plugin be a part of your ordinary Eclipse installation, you will need to export it to a jar and copy that jar to the dropins catalog.

I am using Eclipse JUNO IDE in which I have imported an eclipse plugin project.
When I execute the project, a new copy of the eclipse window is opened and the plugin is displayed in the File Menu as "New Sample Project" in between the "New" option and "Open File" option. The plugin works normally.
From this project I wanted to know which file executes first and how the execution proceeds.
While this is the way to find the order of execution of a simple java program, is there a way to find the code execution order of a plugin project, which has many packages and each package has many java files?
I am new to eclipse plug-in development. Please help
Eclipse plugin project is different than normal Java project and also its execution.
Before jumping into execution steps, I think you better go through plugin project Manifest file details. It will give you overview of plugins that are contributed into your new eclipse instant and their implementation class in project.
Go through different tab in the manifest file. I will brief some of important things for you:
Overview: General info of you plugin. In general information section you will find Activator, which points your activator of plugin which will load your plugin.(You can say it as starting point as it controls plugin life cycle but not clearly starting point)
Dependencies: Plugins required and on which your projects are depended.
Extension: Here you will add Extension Points required for your plugin like view, editor, action,command. Here you can see overview of things which will be contributed through your plugin project.
Hope this helps.
Recently I pulled a project form Github. The language I'm working with is C. When I try to run it, it will say "The selection cannot be launched, and there are no recent launches." I can't compile either. So what I did was search the internet for how to fix this. And the mighty internet said I shall change my run configurations and select my project and then run that. This is what I tried - I opened the configurator and browsed for my project, but it wasn't displayed. I can see the project in the navigator and I can commit/push/pull as well. Still, I can't choose it in the run configurator. Any ideas what I could do?
Thank you very much!
PS: I already saw this post (Can't run project in Eclipse imported from Git) but there is no maven option when importing.
I installed Eclipse Luna in XP yesterday and opened the sample project "Mutlipage Editor". When I click "Run" all that happens is another copy of Eclipse opens looking like the first copy but all the workspace boxes are empty.
I guess I was expecting either an emulator to start or the ability to run it on my Android phone. Can anyone get me started please?
When you run an Eclipse plugin it has to run in an instance of Eclipse so that all the other plugins that the plugin depends on are available.
The default 'Multipage Editor' is associated with a file type (.mpe I think). So create a file with that type and open it to see the editor.
You can also write an Eclipse Rich Client Program (RCP) where you can select the available plugins and the look of the UI, but this requires additional code.
I have the source code for the VersionOne plugin. I am wanting to modify the code because I am getting a NullPointerException when I click a specific button on the plugin which crashes eclipse. I was wondering what steps I need to take in eclipse to import the source code, modify it, and get it to run. I have read over how to create a new plugin project, but I have never tried importing a plugin before. Plugin Source
Once you have imported the project and that seems to work fine, just run it like any other plugin.
I.e:
Set the breakpoints you want in the code
Click the "Run as..."
In the run dialog start up a new Eclipse instance
On the tab "plugins" make sure your imported plugin is selected
If you are using the plugin at the same time, make sure that the non-workspace is not selected
In the new Eclipse instance, set up a situation that will provoke the bug
You need the following things to do that:
From Eclipse download a distro with PDE (Plugin Development) included.
The source pages
Some configuration management tool like Git or Subversion.
You do then the following steps:
Unzip your sources locally somewhere and add them to the CM system.
Create an eclipse plugin project from that source location (depending on Git or SVN different steps).
Create a run configuration for Eclipse that includes that plugin. That is similar to creating a run configuration for Java, but your Java application is then eclipse (see the Help on Eclipse Application Launcher). You have to ensure that in the "Plug-ins Tab", your new plugin is included. After you have started it, you should see the new feature implemented in the new running eclipse. To debug it, you just have to press the debug button instead of the run button. You may then add breakpoints to the source code of your plugin to see how it is working.
You are then able to start a new eclipse application which includes the plugin and make your tests there. You are able to set breakpoints, debug the code and so on. If you find the error, you can change the code, test it, and as a result have a difference to the source you had initially. The best would be then to make a patch and send it back to the originator.
To deploy it then to others is a different story, and is well documented.
I've followed this tutorial:
Eclipse Plugin
This tutorial explain why create a HTML Editor.
I need a Text editor,just for auto-highlight some words, anyway I thought this tuto should be a good one to start with.
The thing is that I created the Plugin project and the only thing that I changed it was the extension "pat" instead "html, htm", just that. After that I created a .pat file, but eclipse doesn't open it with my plugin, and my text editor is not in the editor's list.
Any suggestion??
Let me know if you need more information.
My guess is that you have just created the plugin, but aren't running it in your current Eclipse instance. That can be verified by opening the view "Plugin registry". That will show a list of all plugins, see if the plugin you have created is in that list.
