Hi can anyone tell me what is going wrong?
I am working through the book 'Contributing to eclipse by Erich Gamma &
Kent Beck'. Nothing wrong with chapter 1 example - hello world.
Chapters 4-11 introduce a JUnit testing plugin to add a menu item to a
JUnit project to run a test. This is where my problems start I copied the
code from the book for chapters 4-6. Code comples ok but when I try to run
it in the runtime workbench I get a message that jar file cannot be found.
So I went to books site (http://www.awprofessional.com/titles/0321205758#)
and downloaded example code from there. Same problems occur, on loading
their source project code I get errors such as
"Project org.eclipse.contribution.junit is missing required Java project:
'org.eclipse.core.boot' "
Also the plug-in dependencies did not appear in package explorer.
To remove these errors I ran PDE Tools > Migrate to 3.0 which seemed to
update the paths etc so the code compiled ok. However when I run the
runtime workbench, create a junit project and try to run the menu item
created by the plugin I keep getting
org.eclipse.core.runtime.CoreException[0]: java.io.FileNotFoundException:
/contribjunit.jar
Which I assume means that the plugin cannot find the jar file and there is
a path problem but I dont know how to fix it.
I ve looked at this for several hours now can anyone help? Ive tried both
eclipse 3.01 and 3.1 and get the same results.
The plugin.xml file is
<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.0"?>
<plugin
id="org.eclipse.contribution.junit"
name="JUnit Plug-in"
version="1.0.0"

Normally, PDE will create a classpath to load your classes from your
workspace, and not the JAR.
Not seeing the entire stack dump in the exception, I am guessing here that
someone parses the plugin.xml and tries to find the jar.
If you examine your workspace, you will notice there is no jar (yet).
To get your plugin to work, you could right mouse click on plugin.xml and
generate a build.xml from the PDE sub menu.
Once you have the build.xml, right mouse click and run it.
Then, you should have the jar file.
However, this means you have to recreate the jar, each time before you
launch the runtime workbench.

Thanks for the information Chris. I followed your instructions and
everything worked ok.

maybe this is useful to someone: I had the same problem, and (as a quick
fix, I'm not yet sure if this doesn't bring up another problem) simply
did the following (after a couple of hours trying to get it work another
way):
I uncommented the following lines in TestRunner.java:
//classPath[1]=
// Platform.asLocalURL(new URL(url, "contribjunit.jar")).getFile();
as this is the above mentioned piece of code that tries to load the jar.
After that, the JUnit Plugin Test ran without errors and I didn't get
the IOException for /contribjunit.jar any more.
