## Documentation
-* [Changelog](https://github.com/jenkinsci/workflow-durable-task-step-plugin/releases)
+The nodes and processes plugin also called workflow durable task steps locks jenkins agents with the processes running on them, thereby adding durability to workflows. This ensures Pipelines can resume after an unforseeable restart.
+
+### Pipelines
+
+The plugin provides a `ws` step to allocate a workspace, however, this is created automatically using the `node` step. The [Pipeline Syntax Snippet Generator](https://www.jenkins.io/doc/book/pipeline/getting-started/#snippet-generator) guides the user on usage, practical examples and more information.
+
+### Node
+
+A node is the machine on which Jenkins runs, it is part of the Jenkins environment and is capable of executing a Pipeline.
+The `agent` syntax is equivalent to the `node` syntax except in different spheres. agent is a [declarative syntax](https://www.jenkins.io/doc/book/pipeline/#declarative-pipeline-fundamentals) that is used to specify the executor and workspace on which the Pipeline will be executed while node is [scripted syntax](https://www.jenkins.io/doc/book/pipeline/#scripted-pipeline-fundamentals) that is used to execute Pipelines (and any stages contained within it), on any available agent/node
+
+### Processes
+
+A process in Jenkins can be defined as the continuous integration and continuous delivery of builds, tests, analysis, and deployment of projects and any other scenario that can be automated. The steps in these processes are documented in the jenkinsfile which can be created manually or added automatically using Blue Ocean.
+
+Examples of nodes and processes in respect to declarative and scripted pipeline
+1. A scripted pipeline example can be found [here](https://www.jenkins.io/doc/book/pipeline/#scripted-pipeline-fundamentals)
+
+2. A declarative pipeline example can be found [here](https://www.jenkins.io/doc/book/pipeline/#declarative-pipeline-fundamentals), refer to the [Pipeline Syntax Snippet Generator](https://www.jenkins.io/doc/book/pipeline/getting-started/#snippet-generator) and for more information
+
+### Using multiple agents and setting labels
+
+It is possible to run Jenkins pipeline on multiple agents. Pipelines that can run on low resource can be paired with equal powered agents and high resource agents with equal powered pipelines to avoid unnecessarily long build time.
+
+A declarative pipeline with multiple agents:
+
+```
+pipeline {
+ agent none
+ stages {
+ stage('Build') {
+ agent any
+ steps {
+ checkout scm
+ sh 'make'
+ stash includes: '**/target/*.jar', name: 'app'
+ }
+ }
+ stage('Test on Linux') {
+ agent {
+ label 'linux'
+ }
+ steps {
+ unstash 'app'
+ sh 'make check'
+ }
+ post {
+ always {
+ junit '**/target/*.xml'
+ }
+ }
+ }
+ stage('Test on Windows') {
+ agent {
+ label 'windows'
+ }
+ steps {
+ unstash 'app'
+ bat 'make check'
+ }
+ post {
+ always {
+ junit '**/target/*.xml'
+ }
+ }
+ }
+ }
+}
+```
+A scripted pipeline with multiple agents
+
+```
+stage('Test') {
+ node('linux') {
+ checkout scm
+ try {
+ unstash 'app'
+ sh 'make check'
+ }
+ finally {
+ junit '**/target/*.xml'
+ }
+ }
+ node('windows') {
+ checkout scm
+ try {
+ unstash 'app'
+ bat 'make check'
+ }
+ finally {
+ junit '**/target/*.xml'
+ }
+ }
+}
+```

When using the returnStdout
flag, you probably wish to prefix this with @

lest the command itself be included in the output.

The bat step is used to run pipelines on a windows environment,
+ if your pipeline will run on a Linux environment, use the sh
step.
+
To use the bat step, you have to first point it to the path where your bat file exists, and then 'call' command to trigger that bat file. Examples below:
+This example calls mybat.bat file inside the example folder, extra backslashes are always added to every backslash +Use the Pipeline Snippet Generator to generate the example
+bat 'C:\\example\\mybat.bat'
An example of a declarative pipeline executing a bat step with the command set
+
+
+ pipeline {
+ agent any
+ stages {
+ stage('Build') {
+ steps {
+ bat 'set'
+ }
+ }
+ }
+ }
+
+

+Print out all the environment variables seen by Windows.
+echo bat(returnStdout: true, script: 'set')
Print out the content of the PATH environment variable on Windows
+bat 'echo %PATH%'
Add the keyword call when running a multi-line script and need the commands to execute sequentially +
+ +Failure to do so will result in only the first line + executing. You can also use ''&'' to chain commands into a single line +but this will make your commands hard to read and prone to mistakes.
+Use the Pipeline Snippet Generator to generate this example
+
+
+ bat """
+ call c:\path\to\conda activate my_env
+ cd c:\\path\\to\\scripts
+ call python test.py ${argument}

+
+
The return status step is used to return the exit status of a script. 0 equals true in shell. An exit code + of 1 will cause jenkins to abort. +
+Use the
+ Pipeline Snippet Generator
+ to generate this example by checking the returnStatus
option
+
sh returnStatus: true, script: 'mvn test'
You can use an if statement to ascertain if the exit status returned 0 or not by assigning your script to + a variable. +
+int status = sh returnStatus: true, script: 'mvn test'
+ if (status != 0){
+ //Take Action
+ }
+
+While it is not advisable, use set +e
to ignore the exit status code 1 when running shell script
See sh
documentation for this value
.trim()
on the result to strip off a trailing newline.
+The stdout
command is usually unchecked by default when using
+the pipeline syntax generator. It can be used with any of the steps in the nodes and processes plugin.
+Refer to the steps reference page for more information on all the steps available.

Use variables to store pipeline steps to encapsulate results.

(you can specify set +e
and/or set +x
to disable those).
+ Use the Pipeline Snippet Generator to generate a sample pipeline script for the sh step + A few examples of usage include:
+ + Creating an output folder +sh "mkdir -p output"
sh "ls -la ${pwd()}"
sh "curl -X POST --data-urlencode \'payload=${payload}\' ${slackURL}"
sh 'mvn test'
The triple-double-quote (""") string literal syntax allows for variable/expression substitution (interpolation), so the backslash (\) is interpreted as a special character "escape".
+Since the first open parentheses is not such a special character, Groovy compilation fails. If your intent is to have literal backslashes in the resulting string, you need to escape the backslashes. That is, use a double-backslash (\\) to substitute for one literal backslash
+Use the Pipeline Snippet Generator to generate this example
+sh ("""
+ sed "s/(AssemblyInformationalVersion\\(\\")(.*)(\\")/\\1${productVersion}\\3/g"
+ AssemblyInfoGlobal/AssemblyInfoGlobal.cs -r
+ """)
+
For double quoted string, Groovy will do interpolation on the string firstly.
+Because the variables are runtime variables of the shell, rather than the variables of Groovy runtime. Groovy can't find the responding value from Groovy variable stack to replace the variables during interpolation.
+So you need to escape all $ if you use double quotes or simply use single quotes which does not support interpolation
+Use the Pipeline Snippet Generator to generate this example
+sh(returnStdout: true, script: "cd \$it; PLAN=\$(terragrunt plan --terragrunt-source-update | landscape);
+ echo \$PLAN; CHANGES=\$(echo \$PLAN | tail -2); echo \$CHANGES"
