Thanks for the info. I'll try that out.

That's reassuring that it's not a problem for the Felix product in
general.
However, I'm not a maven guru, so do not understand the pom.xml file
in a way that leads me to the dependency on jsr14...
Nor do I know which source code you're saying I need to recompile.
Are the Felix OSGI jars what I need to recompile? Felix seems like a
project with a lot of moving parts, so I am kind of lost without a
specific list of what needs to be rebuilt (and where I would download
the packages).
I am just attempting to learn Felix now by using the examples... I
think I'm kind of stuck for the moment, given the ramp-up to rebuild
this stuff and get the examples working.
No better time than the present to start learning...
Looking at the example, I thought it depended on the OSGi JARs, but it
doesn't, so that actually makes it simpler.
Assuming you have felix trunk checked out, go into framework and build
it, then go into the example directories and modify the pom.xml to
depend on framework 4.1.0-SNAPSHOT (which is the trunk version)
instead of 4.0.2, then it will work since the trunk framework no
longer targets jsr14.
Sorry... I think I may need to look at Equinox instead, assuming they
have some examples available also.
Feel free.

Unfortunately, I have a requirement to support Java 7. Is Apache
Felix unusable on Java 7 until something is fixed?
You just need to recompile the source yourself and re-target to
whichever Java platform you want. The next release of the framework
will no longer target jsr14, but this still won't help the example
build with Java 7, since it depends on OSGi JAR files that target
jsr14.

Thanks,

I think the issue is that you are compiling with Java 7 and the
OSGi dependencies have been compiled to target jsr14 (fake generic
support for older JVMs). This used to work prior to Java 7, but
support for jsr14 was removed from Java 7 so now it fails.
Try to build using Java 6 and see if it works.

Dear Felix,
I am having problems building the examples at this page:
http://felix.apache.org/site/apache-felix-application-demonstration.html
The maven command (mvn clean install) is failing with a lot of
complaints. I'll attach the log from building
extenderbased.host. The other example parts (circle, triangle,
etc) give similar error messages.
I believe I am using the default maven for ubuntu 12.04, which
is version 3.0.4-2 now. Is there a dependency on maven2 or is
something else going wrong?
I suspect it's something else... Due to the warnings at the
top of the log trace, I tried installing the maven
project-info-report and site-plugin packages, but neither of
those warnings disappeared afterwards. Those are just warnings
though, and the failures seem related to the BundleTracker or
other classes having changed since the demo was created?
Thanks,
Chris.
