rospack can not find my plugin
Hi, I am following this tutorial http://wiki.ros.org/navigation/Tutori... and write a global planner plugin. my package is robocars, my class name is robocars::PathFollowingGlobalPlanner. Here is my package.xml:
<export>
<!-- Other tools can request additional information be placed here -->
<!-- <nav_core plugin="${prefix}/path_following_global_planner_plugin.xml" /
>-->
<nav_core plugin="${prefix}/path_following_global_planner_plugin.xml" />
</export>
And here is my path_following_global_planner_plugin.xml
<library path="lib/libpath_following_global_planner_lib">
<class name="robocars/PathFollowingGlobalPlanner" type="robocars::PathFollowin
gGlobalPlanner" base_class_type="nav_core::BaseGlobalPlanner">
<description>This is a global planner plugin by robocars project.</descripti
on>
</class>
</library>
PathFollowingGlobalPlanner class compiled fine. "rospack find robocars" can find my package. But when I run "rospack plugins --attrib=plugin nav_core", the plugin did not show up.
Why
