JDK setting and JAVA_HOME not respected by Jenkins job

[Michael Pinnegar]

My current setup is.

JDK 8 selected under the JDK options under the "General" tab.

Here is my groovy DSL script. I'm just executing it for diagnostic purposes.

println "java version" + System.getProperty("java.version")

println "runtime version" + Runtime.class.getPackage().getImplementationVersion()

def env = System.getenv()

//Print all the environment variables.

env.each{

println it

}

As you can see JAVA_HOME is not set from the groovy execution environment's point of view which causes problems when I have Java 8 compiled code on the classpath that needs to be loaded. How can I get this Groovy DSL plugin executing while respecting JDK 8?

Hi Michael,

Just to confirm, Have you declared the JDK 8 installation under the JDK configuration in the global settings of Jenkins? 

Cheers

[Michael Pinnegar]

I have indeed. The combo box for the jobs gets populated with options from the config in jenkins master.

Also this is what the environmental variables say when I look at the environmental variables for the job.

I tried a simple JobDSL and it behaved as I expected, see the below details

I cannot reproduce your environment unfortunately, can you try your example by running a docker jenkins instance?

docker run -p 8080:8080 -p 50000:50000 jenkins:alpine
