Title: Message Title

Mike Pylypyshyn created an issue   Jenkins / JENKINS-55652 Jenkins cannot get config.xml with empty description Issue Type: Bug Assignee: Unassigned Components: core Created: 2019-01-17 13:53 Environment: Jenkins 2.150.1, 2.146 Not related to plugin list Labels: Jenkin config.xml API Priority: Minor Reporter: Mike Pylypyshyn For example we have pipeline with empty description <?xml version="1.1" encoding="UTF-8"?><flow-definition plugin="workflow-job@2.29"> <description></description> <keepDependencies>false</keepDependencies> <properties> <hudson.plugins.buildblocker.BuildBlockerProperty plugin="build-blocker-plugin@1.7.3"> <useBuildBlocker>false</useBuildBlocker> <blockLevel>GLOBAL</blockLevel> <scanQueueFor>DISABLED</scanQueueFor> <blockingJobs/> </hudson.plugins.buildblocker.BuildBlockerProperty> <org.datadog.jenkins.plugins.datadog.DatadogJobProperty plugin="datadog@0.5.6"> <tagProperties/> <tagFile/> <emitOnCheckout>false</emitOnCheckout> </org.datadog.jenkins.plugins.datadog.DatadogJobProperty> </properties> <definition class="org.jenkinsci.plugins.workflow.cps.CpsFlowDefinition" plugin="workflow-cps@2.60"> <script>node { echo 'Hello World' }</script> <sandbox>true</sandbox> </definition> <triggers/> <disabled>false</disabled> </flow-definition> And you try update it with use of POST request to API. So, when you get config.xml at first with GET request and after it, you try to put it back with POST request Jenkins will receive it, but in uncorrect view. Like here (In some reason it deletes <description> tag) <?xml version="1.1" encoding="UTF-8"?><flow-definition plugin="workflow-job@2.29"> <description/> <keepDependencies>false</keepDependencies> <properties> <hudson.plugins.buildblocker.BuildBlockerProperty plugin="build-blocker-plugin@1.7.3"> <useBuildBlocker>false</useBuildBlocker> <blockLevel>GLOBAL</blockLevel> <scanQueueFor>DISABLED</scanQueueFor> <blockingJobs/> </hudson.plugins.buildblocker.BuildBlockerProperty> <org.datadog.jenkins.plugins.datadog.DatadogJobProperty plugin="datadog@0.5.6"> <tagProperties/> <tagFile/> <emitOnCheckout>false</emitOnCheckout> </org.datadog.jenkins.plugins.datadog.DatadogJobProperty> </properties> <definition class="org.jenkinsci.plugins.workflow.cps.CpsFlowDefinition" plugin="workflow-cps@2.60"> <script>node { echo 'Hello World' }</script> <sandbox>true</sandbox> </definition> <triggers/> <disabled>false</disabled> </flow-definition> And this is causes issue when you try to start the job.
