Prior to Talend version 6.3.1, many camel-***alldep jars were available in the cConfig "Inner Modules" list of libraries. Since version 6.3.1, these are no longer available.
This was a side effect of the cMessageEndpoint changes that went into all camel-***-alldep***.jar files, as these have been removed by default. Now you need to manually download them either from the Studio Additional Package dialog or offline from a command line.
If you download from the Studio Additional Package dialog, then you will find these jars under your STUDIO-HOME\plugins\org.talend.libraries.camel.alldeps_*******\lib folder. For more details, check the STUDIO-HOME\esb\Readme_cMessageEndpoint_Libraries.txt file.
