Goal: -DjobName=${env.JOB_NAME}  -DbuildNumber=${env.BUILD_NUMBER}

In earlier posts, I wrote about remote debugging with eclipse. Today i found some interesting eclipse debugging blogs,

Jenkins CLI commands

  

• build: Builds a job, and optionally waits until its completion.
• cancel-quiet-down: Cancel the effect of the "quiet-down" command.
• clear-queue: Clears the build queue
• connect-node: Reconnect to a node
• copy-job: Copies a job.
• create-job: Creates a new job by reading stdin as a configuration XML file.
• delete-builds: Deletes build record(s).
• delete-job: Deletes a job
• delete-node: Deletes a node
• disable-job: Disables a job
• disconnect-node: Disconnects from a node
• enable-job: Enables a job
• get-job: Dumps the job definition XML to stdout
• groovy: Executes the specified Groovy script.
• groovysh: Runs an interactive groovy shell.
• help: Lists all the available commands.
• install-plugin: Installs a plugin either from a file, an URL, or from update center.
• install-tool: Performs automatic tool installation, and print its location to stdout. Can be only called from

XMLPropertyListConfiguration / Plist Parser example


XMLPropertyListConfiguration is having a fantastic API to work with plist files. But there is no much example for this library. After some googling and library analysis, it came to know that it is very very easy to parse the files !. Here is the example.


    @Test
    public void test() {
        try {
            String plistFile = "/Users/plistFile/info.plist";
            XMLPropertyListConfiguration plist = new XMLPropertyListConfiguration();

            HashMap life = new HashMap();
            life.put("Home", "home.png");
            life.put("Office", "browse.png");
            life.put("School", "mycart.png");
            life.put("College", "offers.png");
            plist.addProperty("Life", life);
           
            HashMap phones = new HashMap();
            phones.put("Nokia", "8000");
            phones.put("Samsung", "4000");

            List<String> imagesArray = new ArrayList<String>();
            imagesArray.add("icon1.png");
            imagesArray.add("icon2.png");
            imagesArray.add("icon3.png");
            phones.put("PhoneIcons", imagesArray);
            plist.addProperty("Phones", phones);
           
            List<String> imagesArray1 = new ArrayList<String>();
            imagesArray1.add("icon1.png");
            imagesArray1.add("icon2.png");
            imagesArray1.add("icon3.png");
                       
            Map dashBoard = new HashMap();
            dashBoard.put("imgArray", imagesArray1);

            plist.addProperty("ImageArrayBoard", dashBoard);
            plist.addProperty("ImageArray.innnerLevelTag", "IamInnerLevelTag");
            plist.save(plistFile);

            System.out.println("File saved .... ");
        } catch (Exception e) {
            System.out.println(e.getLocalizedMessage());
        }
    }

Thats All, Happy Coding :)
