After Build Custom Label Incrementer Problem

Hi all,

i have written an after build label incrementer. While build process, latest
build version is entered a property file. On successfull builds, label
incrementer parses the property file for latest build version and returns
newly generated label for current build. But, build log always contains the
previous build version. Since, buildlog is prepared before
afterBuildLabelIncrementer method call. Returned label is set for the next
build process.

I have described this situation in
here<http://jira.public.thoughtworks.org/browse/CC-844>.


As it is mentioned, this can be resolved by JMX instead of patching the
cruisecontrol.jar. However, updating projecy label by using JMX is not
resolve my problem. This is also sets the label of subsequent build.

Here is my code to update project label using JMX interface.

....
public boolean isPreBuildIncrementer() {
        //Must be false. To understand whether project artefact published or
not,
        //incrementer has to be called after build.
        return false;
    }

....
private void updateTargetProjectBuildLabelViaJMX(String buildLabel) {
        String errorMessage = "Error occured while updating project ''{0}''
build label via JMX. Exception details: {1}";
        JMXConnector connector;
        try {
            connector = getJMXConnection();

            MBeanServerConnection mbsc =
connector.getMBeanServerConnection();
            try {
                ObjectName cruiseObjectName =
ObjectName.getInstance("CruiseControl Project:name=" + projectName);
                mbsc.setAttribute(cruiseObjectName, new
Attribute(BUILD_LABEL_ATTRIBUTE_NAME,buildLabel));
            } catch (Exception e) {
                error(MessageFormat.format(errorMessage, projectName,e));
            }
            finally{
                connector.close();
            }

        } catch (MalformedURLException e) {
            error(MessageFormat.format(errorMessage, projectName,e));
        } catch (IOException e) {
            error(MessageFormat.format(errorMessage, projectName,e));
        }
    }

    private JMXConnector getJMXConnection() throws MalformedURLException,
IOException {
        JMXServiceURL serviceURL = new
JMXServiceURL("rmi",getCcHost(),Integer.valueOf(getCcRmiPort()).intValue(),"/jndi/jrmp");

        HashMap<String, String> environment = new HashMap<String, String>();
        environment.put(Context.INITIAL_CONTEXT_FACTORY,
RegistryContextFactory.class.getName());
        environment.put(Context.PROVIDER_URL, "rmi://" + getCcHost() + ":" +
getCcRmiPort());

        JMXConnector connector = JMXConnectorFactory.connect(serviceURL,
environment);
        return connector;
    }

Secondly, it is mentioned in related jira issue comment that this problem
can be resolved by deleting serialized project file. However deleting ser
file after build will result in forcing new build, am i right? If it is
true, this doesnt resolve the problem.
How can i achieve this situation instead of patching the Project.class
located in cruisecontrol.jar?

Thanks in advance.
Regards.
