Re: Jenkins not able to launch the slave due to unrecognizable JAVA_HOME

2024-04-19 Thread 'Maciej Jaros' via Jenkins Users 

Just do this on the agent:

 * Get JDK 17 from Adoptium
   
   (Linux x64 in my case).
 * Unpack to |/var/jenkins|.
 * Rename unpacked “jdk[version]” to “jdk”.
 * Check: |/var/jenkins/jdk/bin/java -version|

Jenkins agent will use |/var/jenkins/jdk/bin/java| over any other version.

Cheers,
Nux

Re: email-ext - Override default - groovy-html.template

2024-04-19 Thread 'christop...@googlemail.com' via Jenkins Users 
Hi,


Oh, email-ext, one of my current favorite topics
I am calling it a little differently and that's working (for me it's jelly 
instead of groovy but groovy worked before also):

def mailbody = '${JELLY_SCRIPT, template="template.jelly"}'
def mailsubject = 'Jenkins Build ' + currentBuild.fullDisplayName + ' 
finished: ' + currentBuild.currentResult
emailext attachLog: false, body: mailbody, recipientProviders: [culprits(), 
brokenTestsSuspects(), brokenBuildSuspects(), upstreamDevelopers()], 
subject: mailsubject

Anyone familiar with that problem: 
"JellyException: Could not parse Jelly script : null"?

I found several solutions to support developing the jelly script:
- the email-ext template-testing link in the job page: not working with 
scripted pipeline
- a couple lines of groovy script for the script console to trigger new 
email execution from a finished job: not working due to syntax problems and 
obviously made for a lot older API
- a lot of published jelly-script snippets to add output from the one and 
other plugin: a lot of syntax errors everywhere

What's the latest best way to develop this stuff? 
Is there any way to trigger exeuction based on an existing job? 
Any way to get that origniating parser exception to find the real issue?

BR,
Christoph
