The PDE build tab allows/encourages the creation of JAR files. However, this
seems to conflict with the self-hosting functionalty.
In MANIFEST.MF, the self-hosting environment depends on having your class
directory listed as part of Bundle-Classpath. However, if you then turn
around and tell the build tab to package that class directory as a JAR, it's
the JAR that has to be on the bundle classpath.
The PDE can't / won't maintain a JAR file as part of the ordinary build
cycle, you have to run the Ant build to get this to happen. So, what do
people do? Run Ant all the time? put both the class dir and the jar name in
the bundle classpath, on the theory that the directory is harmless when
deployed?

In fact, your manifest should say the jar if you want a jar when it is
finally deployed. Again the PDE takes care of this.
See:

For how the PDE works.

Let me see if I'm following here. If I set up build.properties to call for a
jar, and put the jar in the classpath, then the self-hosting will infer the
contents of the jar from this information and manage classpath?
I got into this because I'm failing to find any way to make a
java.nio.charset.spi.Provider work in self-hosting. This requires a META-INF
file, and my META-INF file is never seen by the JRE. I thought that
jar-ifying would do the job.

I've done more of the reading, and I seem to have discovered the following:
1) There doesn't seem to be a way in build.properties to request that an
arbitrary META-INF file be incorporated in a jar.
2) I don't really want to build a JAR at all. I want my java.nio.charset.spi
provider to work.
3) Perhaps I should build a JAR with non-PDE means and incorporate it in
some other plugin, instead.

I feel your pain. As of right now I do not care for the PDE Build, so I set up my Eclipse PDE Projects to run under self hosting and build a homegrown script to generate the desired output for production.
Good Luck,
James E. Ervin
