#69 No metrics being generated.

[Anonymous]

I have checked "Enable metrics" on the project
properties window.
I have set the only Builder on the project to the Metrics
Builder.
When I run "Build Project", it performs the calculation
and then does nothing; it displays the "No metrics
available" message. I am in the Java perspective.
When I run the build from this command-line:

C:\eclipse>java -cp startup.jar
org.eclipse.core.launcher.Main -noupdate -application
org.eclipse.ant.core.antRunner -data workspace -file
workspace\project\build.xml compile

I get output similar to this:

[eclipse.build] Calculating metrics for
com.saillant.qct.flexsmart.fssync.impl..
.
[eclipse.build] Calculating metrics for
com.saillant.my.project.fssync...

[eclipse.build] Building: /project... Done.

[eclipse.build] unknown... Done.
[metrics.export] Exporting metrics to flat per Metric XML
format... ...

BUILD FAILED
C:\eclipse\workspace\flexsmart\build.xml:44:
java.lang.NullPointerException

I get an output like this:

<?xml version="1.0" encoding="UTF-8"?>
<Metrics scope="

Here is my build target:

<target name="compile" depends="clean">
<mkdir dir="${javac.dest}"/>
<javac srcdir="${src.dir}"
destdir="${javac.dest}">
<classpath refid="classpath" />
</javac>
<eclipse.build projectName="flexsmart"
buildType="full" failOnError="true" errorOut="errors.xml"
errorFormat="xml" />
<metrics.export projectName="flexsmart"
file="flexsmart.xml"/>
</target>

I also have a question: where are the results of the
computation stored? I can't find them anywhere. The
folders are marked "Read-only" and I can't turn that off; I
think it's part of Eclipse, right? Thanks for your time; let
me know if I can supply any more information.

I'm sorry for missing one detail:

The problem started when Eclipse I was using 1.3.5 with
Eclipse 3.0.1 and Eclipse crashed. I was prompted to reset
the Perspective and the plug-in never worked again. I have
since installed 3.1 on top of the previous installation and then
was unable to uninstall or upgrade 1.3.5, so I deleted the
entry from "feature", "plugin", and deleted site.xml and
reinstalled 1.3.6. It still doesn't work.

I managed to fix this by uninstalling the application,
then manually deleting the data refering to this project
in workspace/.metadata.

Not knowing much about administering or developing with
Eclipse, I only then found the log files under this
folder, which list the following errors, which may or may
not have anything to do with the above problem:
