The following situation.
The goal: from Jenkins pipeline (Jenkinsfile from SCM) to trigger some other build job X. But before that, for some purposes of further sophisticated configuration, I want to parse the config.xml of that build job X and to extract its value “remote”, which is the path to repository of the build job X.
I have constructed a correctly working path to the config.xml of the build job X and now I can do readFile for the config.xml.
This is what my config.xml looks like:
<?xml version='1.1' encoding='UTF-8'?>
<project>
<description>Just a sample build job that should always be successful.</description>
<keepDependencies>false</keepDependencies>
<properties>
<hudson.plugins.jira.JiraProjectProperty plugin="[email protected]"/>
</properties>
<scm class="hudson.scm.SubversionSCM" plugin="[email protected]">
<locations>
<hudson.scm.SubversionSCM_-ModuleLocation>
<remote>http://LAPTOP/svn/localrepo/CCC/COMPONENT/RC</remote>
<credentialsId>someid</credentialsId>
<local>.</local>
<depthOption>infinity</depthOption>
<ignoreExternalsOption>true</ignoreExternalsOption>
<cancelProcessOnExternalsFail>true</cancelProcessOnExternalsFail>
</hudson.scm.SubversionSCM_-ModuleLocation>
</locations>
<excludedRegions></excludedRegions>
<includedRegions></includedRegions>
<excludedUsers></excludedUsers>
<excludedRevprop></excludedRevprop>
<excludedCommitMessages></excludedCommitMessages>
<workspaceUpdater class="hudson.scm.subversion.UpdateUpdater"/>
<ignoreDirPropChanges>false</ignoreDirPropChanges>
<filterChangelog>false</filterChangelog>
<quietOperation>true</quietOperation>
</scm>
<canRoam>true</canRoam>
<disabled>false</disabled>
<blockBuildWhenDownstreamBuilding>false</blockBuildWhenDownstreamBuilding>
<blockBuildWhenUpstreamBuilding>false</blockBuildWhenUpstreamBuilding>
<triggers/>
<concurrentBuild>false</concurrentBuild>
<builders/>
<publishers>
<hudson.plugins.ws__cleanup.WsCleanup plugin="[email protected]">
<patterns class="empty-list"/>
<deleteDirs>false</deleteDirs>
<skipWhenFailed>false</skipWhenFailed>
<cleanWhenSuccess>true</cleanWhenSuccess>
<cleanWhenUnstable>true</cleanWhenUnstable>
<cleanWhenFailure>true</cleanWhenFailure>
<cleanWhenNotBuilt>true</cleanWhenNotBuilt>
<cleanWhenAborted>true</cleanWhenAborted>
<notFailBuild>false</notFailBuild>
<cleanupMatrixParent>false</cleanupMatrixParent>
<externalDelete></externalDelete>
<disableDeferredWipeout>false</disableDeferredWipeout>
</hudson.plugins.ws__cleanup.WsCleanup>
</publishers>
<buildWrappers/>
</project>
This is console output of the Jenkins pipeline for echo:
project[attributes={}; value=[description[attributes={}; value=[Just a sample build job that should always be successful.]], keepDependencies[attributes={}; value=[false]], properties[attributes={}; value=[hudson.plugins.jira.JiraProjectProperty[attributes={[email protected]}; value=[]]]], scm[attributes={class=hudson.scm.SubversionSCM, [email protected]}; value=[locations[attributes={}; value=[hudson.scm.SubversionSCM_-ModuleLocation[attributes={}; value=[remote[attributes={}; value=[ http://LAPTOP/svn/localrepo/CCC/COMPONENT/RC]], credentialsId[attributes={}; value=[someid]], local[attributes={}; value=[.]], depthOption[attributes={}; value=[infinity]], ignoreExternalsOption[attributes={}; value=[true]], cancelProcessOnExternalsFail[attributes={}; value=[true]]]]]], excludedRegions[attributes={}; value=[]], includedRegions[attributes={}; value=[]], excludedUsers[attributes={}; value=[]], excludedRevprop[attributes={}; value=[]], excludedCommitMessages[attributes={}; value=[]], workspaceUpdater[attributes={class=hudson.scm.subversion.UpdateUpdater}; value=[]], ignoreDirPropChanges[attributes={}; value=[false]], filterChangelog[attributes={}; value=[false]], quietOperation[attributes={}; value=[true]]]], canRoam[attributes={}; value=[true]], disabled[attributes={}; value=[false]], blockBuildWhenDownstreamBuilding[attributes={}; value=[false]], blockBuildWhenUpstreamBuilding[attributes={}; value=[false]], triggers[attributes={}; value=[]], concurrentBuild[attributes={}; value=[false]], builders[attributes={}; value=[]], publishers[attributes={}; value=[hudson.plugins.ws__cleanup.WsCleanup[attributes={[email protected]}; value=[patterns[attributes={class=empty-list}; value=[]], deleteDirs[attributes={}; value=[false]], skipWhenFailed[attributes={}; value=[false]], cleanWhenSuccess[attributes={}; value=[true]], cleanWhenUnstable[attributes={}; value=[true]], cleanWhenFailure[attributes={}; value=[true]], cleanWhenNotBuilt[attributes={}; value=[true]], cleanWhenAborted[attributes={}; value=[true]], notFailBuild[attributes={}; value=[false]], cleanupMatrixParent[attributes={}; value=[false]], externalDelete[attributes={}; value=[]], disableDeferredWipeout[attributes={}; value=[false]]]]]], buildWrappers[attributes={}; value=[]]]]
My code that works OK:
def triggered_job_config_file = JENKINS_HOME + '\\jobs\\' + RUNLIST[element] + '\\config.xml'
def xml_file = readFile triggered_job_config_file
def xml_file_contents = new XmlParser().parseText(xml_file)
My code that does not work OK:
Approach A code:
def remote_scm_path = xml_file_contents.project.locations.hudson.scm.SubversionSCM_-ModuleLocation.remote
echo remote_scm_path.toString()
Approach A exception:
org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: No such field found: field groovy.util.Node project
Approach B code:
def remote_scm_path = xml_file_contents.remote
echo remote_scm_path.toString()
Approach B exception:
org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: No such field found: field groovy.util.Node remote
Approach C code:
echo "${xml_file_contents.project.locations.hudson.scm.SubversionSCM_-ModuleLocation.remote.text()}"
Approach C exception:
org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: No such field found: field groovy.util.Node project
My question: does anybody have a good idea, how I can traverse to the value of "remote" in config.xml, which is this one: http://LAPTOP/svn/localrepo/CCC/COMPONENT/RC
Thanks!
If you can use a shell command with an xpath expression :
