Unabe to Start Jenkins on Gradle installed Server - jenkins

I installed Gradle with following versions and was working perfectly fine,
 Gradle server has Java version,
openjdk version "1.8.0_342"
OpenJDK Runtime Environment (build 1.8.0_342-b07)
OpenJDK 64-Bit Server VM (build 25.342-b07, mixed mode)
and gradle version:
Gradle 6.8.3
I would be able to run "./gradlew build" to build our github repository successfully.
 
But,
 When I tried Installing Jenkins on the same server,I'm not able start jenkins i,e. systemctl start jenkins
this is throwing below error:
"Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details."
I wonder, this would be because Java version , because jenkins requires "Java-jdk11".
 
I tried to installed java-jdk11, jenkins was running up and fine , but not able to run gradle command - "./gradlew build" (we can run this command if java version is -openjdk version "1.8.0_342").
 
is there any way to come out this?
Thanks for your Help!

Unable to run groovy scripts with latest jenkins version

I am in the process of upgrading jenkins server to latest LTS version (2.204.2 to 2.251.2) in my current work environment.
In present scenario jenkins installation and configuration is an automated process via chef.
The problem starts here :
i need to upgrade my jenkins server to latest LTS version via chef cookbook
remoting option has been obsolete in latest jenkins version
my present cookbook uses jenkins_script resource (using jenkins 6.0 cookbook from supermarket) to run groovy scripts
i am able to upgrade my jenkins server but unable to execute groovy scripts via jenkins-cli, its picking remoting option all the time and failing even though its obsolete in latest version
Is there any automated way to change protocol from remoting to ssh/http when chef client runs
.
Any valuable inputs will be helpful

Running jenkins on ubuntu subsystem of Windows

I was able to install and run jenkins on my linux subsystem in Windows 10.
It listens on 8082.
But unfortunately, for an unknown reason, it hangs up infinitely after a few minutes (or to be precise after a I've made a change in a job config and execute a build).
Then, I checked in the terminal:
root#jup1t3r /h/navds# service jenkins status
Correct java version found
2 instances of jenkins are running at the moment
but the pidfile /var/run/jenkins/jenkins.pid is missing
root#jup1t3r /h/navds# service jenkins stop
Correct java version found
* Stopping Jenkins Automation Server jenkins
...done.
root#jup1t3r /h/navds# service jenkins status
Correct java version found
2 instances of jenkins are running at the moment
but the pidfile /var/run/jenkins/jenkins.pid is missing
So there is no way to stop Jenkins. How can I restart it ?

Jenkins Builds Fail Using the Gradle Daemon

While trying to improve performance of my Gradle Android builds, I stumbled across the Gradle Daemon, and have been using it with great success for local builds.
However, when running under Jenkins on Ubuntu 14.04, builds are intermittently failing with:
Starting process 'Gradle Test Executor 2'. Working directory: /tmp/myproject/android/example Command: /usr/lib/jvm/java-8-oracle/bin/java -Djava.awt.headless=true -Djava.security.manager=worker.org.gradle.process.internal.worker.child.BootstrapSecurityManager -Dfile.encoding=UTF-8 -Duser.country=US -Duser.language=en -Duser.variant -ea -cp /data/var/lib/jenkins/.gradle/caches/2.14.1/workerMain/gradle-worker.jar worker.org.gradle.process.internal.worker.GradleWorkerMain 'Gradle Test Executor 2'
Successfully started process 'Gradle Test Executor 2'
Daemon vm is shutting down... The daemon has exited normally or was terminated in response to a user interrupt.
Starting process 'Gradle Test Executor 3'.

----- End of the daemon log -----
FAILURE: Build failed with an exception.
* What went wrong:
Gradle build daemon disappeared unexpectedly (it may have been killed or may have crashed)
* Try:
Run with --stacktrace option to get the stack trace. Run with --debug option to get more log output.
Error: Failed to run test (./gradlew --console=plain --info test -p myproject).
FAILURE: Build failed with an exception.
Multiple builds may be running in parallel. If I run a build manually when no other builds are running, I haven't been able to reproduce it. Someone else had this problem, but the recommended solution was just to disable the Gradle Daemon, which I don't want to do. I would think that a large, concurrent build environment would be exactly what Gradle Daemon was intended to optimize.
Or, if I can't make the Gradle Daemon work reliably under Jenkins, why not? Thanks!
The Gradle Daemon is enabled by default since version 3.0. However, the official documentation until 4.2.1 stated that you shouldn't use the daemon in continuous integration servers.
It is recommended that the Daemon is used in all developer environments. It is recommend to disable the Daemon for Continuous Integration and build server environments.
The Daemon enables faster builds, which is particularly important when a human is sitting in front of the build. For CI builds, stability and predictability is of utmost importance. Using a fresh runtime (i.e. process) for each build is more reliable as the runtime is completely isolated from previous builds.
This recommendations has changed since then, see Disabling the Daemon
Since Gradle 3.0, we enable Daemon by default and recommend using it for both developers' machines and Continuous Integration servers. However, if you suspect that Daemon makes your CI builds unstable, you can disable it to use a fresh runtime for each build since the runtime is completely isolated from any previous builds.
