In Eclipse, when I open the POM for one of my projects I am getting the error "Project build error: Unknown packaging type: iso".
I have create a plugin that handles builds for packaging type of iso. I have modified the pom.xml to reference that plugin and the build runs fine from the command line. My question is, how to I tell m2eclipse about my plugin so that it doesn't complain about the packaging type? I have dug through the various configuration files in the workspace/.metadata directory and googled for the error message but haven't found any answer. Anybody know?
The trick seem to be to restart Eclipse. At least that is the only thing I can come up with because the next day when I started Eclipse and opened the offending POM, Eclipse was happy and no longer complained about the packaging type.
By the way, before I restarted I tried: resaving the pom.xml, cleaning the project, building the project, refreshing the project. None of those removed the unknown packaging error.
