How to implement the Post-Build phase using the Jenkins Pipeline plugin?

Question

After reading the Jenkins tutorial explaining the Pipeline plugin, it seems that the plugin should allow you to perform Post-Build . However, the documentation is rather limited in relation to specific instructions.

For example, I am wondering how to implement:

• Run only if assembly completed successfully
• Run only if the assembly is successful or unstable.
• Run regardless of build result

• Run only if build completed successfully

  stage 'build'
  ... build
  ... tests
  stage 'post-build'
  ...
  

  (Or add -Dmaven.test.failure.ignore=falsein MAVEN_OPTS)

• Run only if build was successful or unstable

  stage 'build'
  ... build
  try {
      ... tests
  } catch {
      ...
  }
  stage 'post-build'
  ...
  

  (Or add -Dmaven.test.failure.ignore=truein MAVEN_OPTS)

• - try / catch / finally?

  try {
      stage 'build'
      ...
  } catch {
      ...
  } finally {
      stage 'post-build'
      ...
  }
  

( , SUCCESS, , .. "", , . , .. currentBuild.result = 'UNSTABLE'?)

- post build action script.

try/catch , , currentBuild.result = 'UNSTABLE' .. , , JUnit Report, , junit. , .

stage 'build'
... build
try {
    ... tests
} catch(err) {
    //do something then re-throw error if needed.
    throw(err)

try-catch , .

:

try {
    node {
        sh 'sleep 20' // <<- can abort here
    }
} catch (Exception e) {
    println 'catch'
} finally {
    println 'finally'
}

node {
    println 'second'
}

try {
    node {
        sh 'sleep 20' // <<- can abort here again
    }
} catch (Exception e) {
    println 'catch'
} finally {
    println 'finally'
}

FWIW, , , try/catch/finally . finally, , , , finally:

def currResult = currentBuild.result ?: 'SUCCESS'
def prevResult = currentBuild.previousBuild?.result ?: 'NOT_BUILT'

// Identify current result
boolean isAborted = (currResult == 'ABORTED')
boolean isFailure = (currResult == 'FAILURE')
boolean isSuccess = (currResult == 'SUCCESS')
boolean isUnstable = (currResult == 'UNSTABLE')

boolean isChanged = (currResult != prevResult)
boolean isFixed = isChanged && isSuccess && (prevResult != 'ABORTED') && (prevResult != 'NOT_BUILT')
boolean isRegression = isChanged && currentBuild.resultIsWorseOrEqualTo(prevResult)

onAlways()
if (isChanged) {
    onChanged()
    if (isFixed) {
        onFixed()
    } else if (isRegression) {
        onRegression()
    }
}
if (isSuccess) {
    onSuccess()

    if (isAborted) {

    if (isFailure) {
