Re: RE: [equinox-dev] OSGI Bundles: alternate manifest.mf location

Just to add to what Alex said below - I understand that the OSGI package needs the META-INF in the jar at top level. All I am asking is that the source location in OSGI plugin project could be anywhere (like resources/META-INF/MANIFEST.MF) that gets relocated to META-INF/MANIFEST.MF for final bundle package. 

The reason I am doing this is to use "Apache Maven" for headless builds and use Eclipse as IDE for OSGI bundles. Currently I am using normal java project for OSGI bundles as I can not relocate the META-INF and let build.properties know about it. Seems like all you need is to introduce an extra property to inform the PDE as to where META-INF is located. Just with this functionality I would be able to build OSGI bundles in both (Maven abd Eclipse) with the same source layout

That's only in the final Jar, though. There's no reason that it
couldn't be stored in different locations when it's being built in
source form. (But I suspect it's hard-coded in the PDE runtime.) As
long as it exports a Jar in the right place (just like classes may be
compiled to /bin or /classes, but there's no /bin or /classes in the
output Jar) then there should be no reason why this can't be done in
PDE.
