why plugin built via Tycho working with JDT but not CDT - eclipse

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:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

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
