Jenkins Environment variables

No comments: Posted by Kaleeswaran at 8:54 PM Labels:



Jenkins is having many environment variables, Each environment variable is very important one or other way. Lets see how can we use these variables efficiently  in jenkins.

E.g : BUILD_NUMBER

While archiving each build on a job. We can name the build such as MyJob_1.

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



Environment Variable Description
BUILD_NUMBER The current build number, such as "153"
BUILD_ID The current build id, such as "2005-08-22_23-59-59" (YYYY-MM-DD_hh-mm-ss)
BUILD_URL The URL where the results of this build can be found (e.g. http://buildserver/jenkins/job/MyJobName/666/)
NODE_NAME The name of the node the current build is running on. Equals 'master' for master node.
JOB_NAME Name of the project of this build. This is the name you gave your job when you first set it up. It's the third column of the Jenkins Dashboard main page.
BUILD_TAG String of jenkins-${JOB_NAME}-${BUILD_NUMBER}. Convenient to put into a resource file, a jar file, etc for easier identification.
JENKINS_URL Set to the URL of the Jenkins master that's running the build. This value is used by Jenkins CLI for example
EXECUTOR_NUMBER The unique number that identifies the current executor (among executors of the same machine) that's carrying out this build. This is the number you see in the "build executor status", except that the number starts from 0, not 1.
JAVA_HOME If your job is configured to use a specific JDK, this variable is set to the JAVA_HOME of the specified JDK. When this variable is set, PATH is also updated to have $JAVA_HOME/bin.
WORKSPACE The absolute path of the workspace.
SVN_REVISION For Subversion-based projects, this variable contains the revision number of the module. If you have more than one module specified, this won't be set.
CVS_BRANCH For CVS-based projects, this variable contains the branch of the module. If CVS is configured to check out the trunk, this environment variable will not be set.
GIT_COMMIT For Git-based projects, this variable contains the Gitish of the commit checked out for the build
GIT_BRANCH For Git-based projects, this variable contains the Git branch that was checked out for the build (normally master)

  • logout: Deletes the credential stored with the login command.
  • mail: Reads stdin and sends that out as an e-mail.
  • offline-node: Stop using a node for performing builds temporarily, until the next "online-node" command.
  • online-node: Resume using a node for performing builds, to cancel out the earlier "offline-node" command.
  • quiet-down: Quiet down Jenkins, in preparation for a restart. Don't start any builds.
  • reload-configuration: Discard all the loaded data in memory and reload everything from file system. Useful when
    you modified config files directly on disk.

  • safe-restart: Safely restart Jenkins
  • safe-shutdown: Puts Jenkins into the quiet mode, wait for existing builds to be completed, and then shut down
    Jenkins.
  • set-build-description: Sets the description of a build.
  • set-build-display-name: Sets the displayName of a build
  • set-build-result: Sets the result of the current build. Works only if invoked from within a build.
  • shutdown: Immediately shuts down Jenkins server
  • update-job: Updates the job definition XML from stdin. The opposite of the get-job command
  • version: Outputs the current version.
  • wait-node-offline: Wait for a node to become offline
  • wait-node-online: Wait for a node to become online
  • who-am-i: Reports your credential and permissions

XMLPropertyListConfiguration / Plist Parser example

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 :)

How to print base64 image in jasper report pdf ?

1 comment: Posted by Kaleeswaran at 10:44 PM Labels: , , ,

How to print base64 image in jasper report pdf ?

1) import base64 class in jrxml file <import value="org.apache.commons.codec.binary.Base64"/>

2) Create two parameters logo and base64Img in jasper report.

3) logo parameter class as String (java.lang.String) and

4) base64Img parameter class as InputStream (java.io.InputStream) and

5) base64Img parameter Default Value expression should be like "new ByteArrayInputStream(new Base64().decodeBase64($P{logo}.getBytes("UTF-8")))"

Thats all..

Note :
parameter class - specifies the type of that parameter
Default Value expression - just like method. we can write our implementation here.

    @Test
    public void base64ImageAsStream() {
        try {
            compileReports();
            System.out.println("report ");
            String outFileNamePDF = "/Users/user/Tried/POC/imageStreamToPdf/base64ImageStream.pdf";
            new File(outFileNamePDF).getParentFile().mkdirs();
            String containerJrxmlFile = "/Users/user/Tried/POC/imageStreamToPdf/imageToStreamPdf.jrxml";
           
            Map<String, Object> parameters = new HashMap<String,Object>();
            File img = new File("/Users/user/Desktop/wallpaper.jpg");
            InputStream fis = new FileInputStream(img);
           
            byte[] imgByte = null;
            imgByte = IOUtils.toByteArray(fis);
            byte[] encodedImage = Base64.encodeBase64(imgByte);
            String encodeImg = new String(encodedImage);
           
            System.out.println("printnng");
            parameters.put("logo", encodeImg);
           
            InputStream reportStream = new FileInputStream(containerJrxmlFile);
            BufferedInputStream bufferedInputStream = new BufferedInputStream(reportStream);
            JasperDesign jasperDesign = JRXmlLoader.load(bufferedInputStream);
           
//            JasperReport jasperReport = (JasperReport) JRLoader.loadObject("/Users/user/Tried/POC/imageStreamToPdf/imageToStreamPdf.jasper");
           
            JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
            JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, new JREmptyDataSource());
           
            JRExporter exporter = new net.sf.jasperreports.engine.export.JRPdfExporter();
            exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, outFileNamePDF);
            exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
            exporter.exportReport();
           
            System.out.println("pdf report created .... ");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Enjoy the coding !!!
