Could not resolve module: org.eclipse.cdt.launch.remote

Question

I am trying to use eclipse's CDT for generating an AST for some cpp files. I am following the instructions given here: http://wiki.eclipse.org/images/c/c7/CDT_APIs_for_code_introspection.pdf

However, I ran into an error saying:

Exception in thread "main" java.lang.IllegalStateException: Workspace is closed.
at org.eclipse.core.resources.ResourcesPlugin.getWorkspace(ResourcesPlugin.java:399)
at etl.CppParser.Parser(CppParser.java:23)**

After googling about it for a while, I understood that in order to access a project in the workspace (using ResourcesPlugin.getWorkspace().getRoot().getFile(path);), the project should be a plugin project, but my project was a simple Java project.

Therefore, I started to developed a plugin project in eclipse. I created a target platform to which I added all the required plugin dependencies required for my project. But I still have a problem when I run the plugin project as an Eclipse application. Here is the exact error:

!ENTRY org.eclipse.cdt.launch.remote 4 0 2013-11-30 01:43:27.379

Could someone please tell me what I could do to get rid of this problem... I am not able to understand what the problem is at this point.

Thank you very much for any help.

Answer 1

The error says that bundle org.eclipse.cdt.launch.remote has a Require-Bundle (osgi.wiring.bundle) statement which lists bundle org.eclipse.rse.ui and the bundle version range [3.0,4.0). So org.eclipse.cdt.launch.remote cannot resolve because it is dependent on bundle org.eclipse.rse.ui having bundle version >=3 and < 4.

Answer 2

Okay, I have solved the problem myself. What I did is as follows: I found this link for Target Management related Downloads and I downloaded the RSE runtime 3.2.2 (it is >=3 and <4)

http://download.eclipse.org/tm/downloads/

Then I went to Eclipse Windows->Preferences->Plugin Development->Target Platform , then selected my Target Platform->Edit-> Add->Directory and add the directory obtained by extracting the downloaded RSE runtime 3.2.2.zip.

After this, when I ran my plug in project as an Eclipse Application, I had no errors anymore because now, the plugins used by my plugin project do not have any unresolved dependencies.

I hope this helps someone.
