26 -1. Checking out the source code from git.
27 -1. If a pom.xml is found your favorite JDK is selected, by default jdk11. Then a maven build is done.
28 -1. If there's no pom.xml but a package.json is found a nodejs build is done.
26 +1. **sdcPipeline **prints some valuable information about this shared Jenkinslib. Allocates a node (Jenkins Agent) to start executing the pipeline.

30 30  1. Then the following stages are executed in parallel
31 -11. Analysis: For maven projects the Java source code is checked by checkstyle, pmd and spotbugs. Furthermore the job output will be checked for any warnings generated by maven, javac or javadoc. If Python modules (.py files) exist in the git repository they will be analyzed using pylint and flake8. If pylint or flake8 are not available on the Jenkins agent the steps will be skipped. Python files that are generated or downloaded into the workspace will not be checked. The results will be displayed on the classical Jenkins build page after the build. For Go projects, the Go test tool is used to run all tests and produce a coverage output file for SonarQube. Additionally, the gotestsum tool is used to produce a report which is picked up by Jenkins.</dd>
32 -11. Security: If it's not a feature or bugfix branch a dependency check is done which checks if e.g. libraries are used which have known vulnerabilities. The results will be displayed in Jenkins after the build.
33 -11. Docker: this will also work for projects which are neither maven or nodejs. A Dockerfile is enough to trigger this part of the pipeline.
34 -111. If a Dockerfile is found a docker image is built.
35 -111. The image is started as an isolated container on the Jenkins agent.
36 -111. Any loglines written to stdout or stderr by the container will be displayed.
37 -111. A smoke test is performed which is a simple query for a valid answer on the exposed port of the container.
38 -111. If the smoke test was successful and the build was not done for a pull request the docker image will be pushed to the docker registry.
39 -111. For easy identification of the image 3 image tags are defined:

38 +111. If Dependency Track is enabled for the current project, an SBOM file is created and archived in the build. In addition it's pushed to Dependency Track. Jenkins will wait for DepTrack to process the SBOM and display information about found potential vulnerabilities in the build.

41 41  1111. BRANCH_NAME-GIT_HASH (e.g. 'develop-8a7c4f2')
42 42  1111. BRANCH_NAME-latest (e.g. 'feature-PKEY-42-latest')
43 43  1111. (If BRANCH_NAME is defaultBranch the prefix 'BRANCH_NAME-' will not be included.)
44 -111. When a chart/Chart.yaml is found and  it's not a pull request a Helm Chart will be created and pushed to the Helm Chart repository.
45 -1. Yamllint will check all YAML files in the workspace for errors and warnings. This is done at this place since the Create Helm Chart stage modifies or creates YAML files which should be also checked before the pipeline proceeds.
46 -1. When depolyHelmChart is set to true the Helm chart will be deployed to the Kubernestes cluster and namespace of your choice. Not done in the example diagram.
