Hi / here is a previous post, I am still lost on this one...
I will happily send a reward for first clue that gets me unstuck...
....you get to pick one of:
(1) the music CD of your choice from Amazon
(2) a frisbee, but, like, a nice frisbee or
(3) a really good Russian novel.
Here is the problem:
I cannot load org.eclipse.debug.core.DebugPlugin at runtime.
Here is a simple code sample that refers to DebugPlugin:
============================================================
DebugPlugin dpi = DebugPlugin.getDefault();
MessageDialog.openInformation(
window.getShell(),
"HelloDebug Plug-in",
dpi.toString());
============================================================ =
1. if I make a Hello World plugin and insert this code, it works fine,
both running under the debugger and deployed in a JAR under a clean copy
of Eclipse.
2. if I insert the code into the plugin that I am actually developing...
2.1 it works fine under the debugger.
2.2 when deployed in a JAR, I get the runtime error:
java.lang.NoClassDefFoundError: org/eclipse/debug/core/DebugPlugin
3. ...but under the very same session the Hello World example still
works fine.
So I must have done something that causes the class loader to fail at
runtime in my plugin only... any idea what that might have been?
It loads hundreds of other classes, this is the only failure.
(thanks)

Both manifests include the dependency on org.eclipse.debug.core (which
is the only reason I can compile in both cases). My plugin has a
dependency on another of my plugins (com.mka.core, listed last).
Here are both manifests:
============================================================ =================

OK, what does the manifest for com.mka.core look like?
Also, you are getting the java.lang.NoClassDefFoundError:
org/eclipse/debug/core/DebugPlugin in the error log, correct?
What are the full stack traces for the first 3 errors in your error log?
Later,
PW

The manifest looks OK, but the build.properties might be wrong (a common
error is to forget the '.' in bin.includes) and hence the JARed plug-in
is not OK. Make sure to enable al PDE compiler detection rules and try this:
1. select your plug-in
2. PDE Tools > Organize Manifests...
3. check all options
4. press Finish
Now check whether somethings changed in your manifest or build.properties.
