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´m beginning with Acceleo.
I installed eclipse-modeling-luna-M6-win32.
Then i installed acceleo by update on eclipse.
(is there any better option?)
Trying to use the uml2java example.
To run it i tried to run org.eclipse.acceleo.examples.uml2java.
It gave me:
Error
Couldn't load class org.eclipse.acceleo.examples.uml2java.main.Uml2java from project org.eclipse.acceleo.examples.uml2java
Couldn't load class org.eclipse.acceleo.examples.uml2java.main.Uml2java. Check that its containing package is exported.
I did not change the code.
I checked the MANIFEST and it has on the runtime: org.eclipse.acceleo.examples.uml2java.main
I also saw that there is an UI project that as i understand is a plugin but i don´t know what to do with it (so that it will create a new menu on eclipse).
Any help is appreciated!!
Thanks.
it worked using eclipse indigo with the latest acceleo. i don´t know if it´s possible to use a more recent eclipse version. also works with eclipse kepler.
This fixed the problem for me. Try adding the "bin/" directory to the Classpath in the Manifest file.
Right click the MANIFEST.MF file and "Open With >" "Plug-in Manifest Editor".
This gives some tabs at the bottom. Use the "Runtime" tab. On the bottom right of this screen there is a place to edit the classpath. Add "bin/".
I got this idea from Etienne's answer in: Can't generate java from UML using Acceleo in Eclipse
I'm trying to get the GNATbench plugin to work with Eclipse. I put the plugin and feature files in the correct places. I restart Eclipse and I am now given the option to create a new Ada project but when I try to do it I get this error:
The selected wizard could not be started. Plug-in com.adacore.gnatbench.cdt was unable to load class
com.adacore.gnatbench.ui.internal.wizards.NewAdaProject. An error
occurred while automatically activating bundle
com.adacore.gnatbench.ui (235).
Any idea what is causing this?
This is the issue you'll see if you attempt to use GNATbench with the 64-bit version of Eclipse. As the system requirements note in the readme, it's only compatible with the 32-bit version. I just did a quick test, which confirmed the issue.
I checked the README file of this plugin, it says this is required:
"C/C++ Development Tools (CDT) plug-in for Eclipse 3.5.x or 3.6.x"
Have you installed that?
The other important thing is that the downloaded archive file is actually a P2 repository installable file. In this case I would unzip a new eclipse (or remove manually the related plugins you copied over, this is the hard way), start it, click on help/install new software, click add, select archive, point to your downloaded GNATbench zip file, select the 2 features appearing on the avail "software" list and continue the wizard normally (next, finish...). If there is a version problem the wizard should "validate" it.
There was a plugin for Ada called Hibachi, IIRC... I'm not sure where it stands on development or completeness though.
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 have just installed Eclipse 3.5 for Java EE developers ("Galileo").
I need to add an extra plugin, but when I select the "Install New Software ..." menu item, nothing happens. Literally nothing - no dialog opens, no error message is displayed. If I have the Debug window open, no message are displayed.
If I go to Preferences -> Install/Update -> Available Software Sites, that dialog opens OK, I can manage the list of update sites, and test the connections, and they all appear OK. But I cannot get to use them to actually install anything.
Is it just broken, or could there be something more subtle wrong?
Thanks.
Start by checking you error log under Window -> Show View -> Error Log. See if you're getting any exception while trying to install new software.
You can also install by downloading the plugin and unzipping it in the dropins folder.
I ran into the same problem. There seems to be a bug related to the finish button (I am assuming this is the same problem you are experiencing). The way I got around it is by clicking on the finish button (or next, or whichever button is not working for you) and press the 'Enter' key. It's annoying. Seems to be an issue with how Eclipse is integrating with GTK.
I had the same problem, took a look at the error log and changed the launcher from "/usr/bin/eclipse" to "sudo /usr/bin/eclipse", it was a permissions thing...
GDK_NATIVE_WINDOWS=true also solved the non-clickable button problem for me running gnome 2.28.1 with Ubuntu Karmic (9.10) x64 with kernel 2.6.31-14-generic
To resolve this problem, I did the following:
Placed my copy of Eclipse in the trash
Emptied my trash
Rebooted my computer
Downloaded the latest version of Eclipse (which was Indigo at the time of writing)
Placed the .zip file in my applications folder
Double-clicked on the compressed zip to open it (I'm using Mac OS X.6)
The problem disappeared. I am now able to do Help/Install new software....
I suggest to use Eclipse Indigo (Eclipse 3.7) which contains EGit already.
Something you can try:
Delete (rename/move) your workspace and try again. Be sure to backup all your projects and settings.
Download the plugin "manually" and use Eclipse>Window>Preferences>Install/Update>Available Software Sites to add it locally.
Download the plugin "manually" and use Eclipse>Window>Help>Software Updates>Available Software>Add site>Archive, find the directory on your HDD and add it.
I had the same problem in windows... and spent couple of hours to "somehow" install the new softwares.
Anyway I will explain you how I managed to install it after trying many options..
Start a fresh copy of eclipse
First tick two check boxes(Show only latest version & Contact all update sites). Make sure the check box of group items is untick.
Try to add software...
If not showing the list of plugins/Next buttons.
Delete the copy of eclipse.
Start a fresh copy of eclipse
Tick only the check box for Contact all update sites.
Now try to add plugins. It worked for me...
Even if it sounds crap... it worked for me..
If none of the solutions above work for you, simply change the workspace to another location. If the list of items appears properly then there's probably something screwed up in the workspace and not Eclipse. Hope this helps.
I actually just had a similar problem and wanted to offer the solution that worked for me. This was not a permissions thing. To solve that I always install eclipse as my user in my local directory (e.g. /home/[user]/local/eclipse-3.7.2) and then you never have permission issues.
Setup: Go to Help -> Install New software -> Available Software Sites (to add new site)
Symptom: Try to add a new site. After hitting enter or clicking finish the site shows up in the list of available sites. Click Okay to go back to the install new software and the site is not available in the drop down. Go back to Available sites and the site is gone.
Fix: After adding the site click on the reload button while the new site is highlighted (before clicking Ok to go back to the "Install new software screen"
This was occurring on Indigo SR2 (and has been happening for a while). I am running this on Linux Gtk -- but I don't see why this would be related.
Hope this helps!
Delete your ~/.eclipse folder and restart eclipse. This is the only thing that worked for me.
I had the exact the same problem. What I found out is that I installed the eclipse as root user. Therefore, I need to be a root user in order to launch "Install New Software".
just press enter after entering URL in "Install new software" window
I faced similar issue. To troubleshoot this issue follow these steps:
Go to windows -> show view -> error.
Check the error logs. In my case error was java.lang.IllegalStateException: Registry Directory not available. at org.eclipse.equinox.internal.p2.engine.SimpleProfileRegistry.restore
I checked my config.ini which is under eclipse -> configuration folder.
I found eclipse.p2.data.area has incorrect path set.
I set the correct path for above key and restarted eclipse. It started working.
Hope it helps
I have faced the same issue. To solve the problem, follow the following steps:
Window (Eclipse Menu) -> Show View -> Error Log
if Error Log is not there, then:
Window (Menu) -> Show View -> Other -> General -> Error Log
Once the Error log is shown, Go to Help (Eclipse Menu) -> Install New Software
Check the Error log, most probable you will see an exception there.
Check the exception, most probable it's caused by java.lang.IllegalStateException
Check the path mentioned in the exception, if you see ".Lock" in the path, close the eclipse then go to the path in windows machine and delete that folder.
now go to the eclipse "exe" file that you're using and open it as an administrator, then try, most probably this will solve the issue.
I`m wondering if this help you.
Let me know if you have any queries.
