[workflow-plugin] no workspace for parallel steps

[Stefan Lorenz]

Hi,

when I try to get the test results from parallel executed steps, I get the following exception, because there is no workspace for the steps to save the test results.

Could you paste a simple workflow that shows this?

From the log, to me it looks like your parallels are executed outside the node and workspace blocks.

[Stefan Lorenz]

stage 'UI-Test'

parallel(suite1: {

node('DockerBuild') {

ws {

catchError {

build  job: 'UITestSuiteRunner', parameters: [new hudson.model.StringParameterValue('mavenProfile', 'ui-test1'), new hudson.model.StringParameterValue('testSuite', 'UiTest1Suite')]

}

step $class: 'hudson.tasks.junit.JUnitResultArchiver', testResults: 'target/surefire-reports/*.xml'

}

}

}, suite2: {

node('DockerBuild') {

ws {

catchError {

build  job: 'UITestSuiteRunner', parameters: [new hudson.model.StringParameterValue('mavenProfile', 'ui-test2'), new hudson.model.StringParameterValue('testSuite', 'UiTest2Suite')]

}

step $class: 'hudson.tasks.junit.JUnitResultArchiver', testResults: 'target/surefire-reports/*.xml'

}

}

}, suite3: {

node('DockerBuild') {

ws {

catchError {

build  job: 'UITestSuiteRunner', parameters: [new hudson.model.StringParameterValue('mavenProfile', 'ui-test3'), new hudson.model.StringParameterValue('testSuite', 'UiTest3Suite')]

}

step $class: 'hudson.tasks.junit.JUnitResultArchiver', testResults: 'target/surefire-reports/*.xml'

}

}

},suite4: {

node('DockerBuild') {

ws {

catchError {

build  job: 'UITestSuiteRunner', parameters: [new hudson.model.StringParameterValue('mavenProfile', 'ui-test4'), new hudson.model.StringParameterValue('testSuite', 'UiTest4Suite')]

}

step $class: 'hudson.tasks.junit.JUnitResultArchiver', testResults: 'target/surefire-reports/*.xml'

}

}

})

I can't obviously see why that would fail - however even if it worked it would not do what I think you expect it to do (copy the unit test results from the invoked job).

The test results need to come from the node&workspace that the workflow has used - however the 'build' step just triggers a regular jenkins job that is run outside of the node/workspace defeined by the flow.

[Stefan Lorenz]

Yeah, that's what I try to achive.

The job is a bit complex, with xfvb, a war deployment, and a maven project with a selenium test...

that's why I stared it with the "build" step... 

Isn't it possible to get the results from inside a "build" step? 

I recognized that the "build" step either has "failure" or "success" as result, never "unstable", even if the test results are "unstable".
