why plugin built via Tycho working with JDT but not CDT

Question

I am so frustrated when trying to find out the reason why the Eclipse plugin I built via Tycho is not working in CDT, but working in JDT. The parent pom.xml looks like the following:

        </executions>
      </plugin>   
    </plugins>

  </build>

</project>

And the pom for abc plugin looke like the following

<?xml version="1.0" encoding="UTF-8"?>
<project>
  <modelVersion>4.0.0</modelVersion>

  <parent>
    <relativePath>../abc-master/pom.xml</relativePath>
    <groupId>com.company.eclipse.plugin</groupId>
    <artifactId>abc-master</artifactId>
    <version>1.0.0</version>
  </parent>


  <artifactId>com.company.eclipse.plugin.abc</artifactId>
  <packaging>eclipse-plugin</packaging>

</project> 

Any help is most appreciated.

Answer 1

thanks a lot for helping me. I suspect it is due to the Eclipse for C/C++ is somehow corrupted. So I download a new CDT, and copy the files from the new CDT to old CDT folder by folder, and try start the old CDT to see if the plugin works. After I replaced the "configuration" folder using new downloaded copy, the plugin works. So means something in the configuration folder in the old CDT prevent the plugin from starting. Unfortunately I forgot to backup the old CDT, so now I am not able to re-product the issue to investigate what is wrong in configuration folder.

Closed as cannot reproduce
