How to change the jenkins home directory location on centos v8?

i installed jenkins on docker via command
docker run -p 8080:8080 -p 50000:50000 -d -v jenkins_home:/var/lib/docker/volumes/jenkins_home/_data jenkins/jenkins:lts
I specified the jenkins_home: /var/lib/docker/volumes/jenkins_home/_data
but i did not understand why so jenkins it displays : Home directory /var/jenkins_home
image here
image here
and what is weird is that this directory (/var/jenkins_home) is empty:
/var/jenkins_home# ll total 0
This causes me problems with the docker build step

maven print phase of the lifecycle during build

How to print which phase running while maven builds the project ? Let us say I run mvn install , then what I see is :

We see the format <plugin_name> : version : goal (execution Id) # artifact name , but I need to see which phase of the lifecycle was active when this is happening ?

I got an complete answer in the comments. So, I am combining them and posting on their behalf.
As #khmarbaise commented , currently this is not possible in maven 3.
But there is something that can be helpful - buildplan-maven-plugin as commented by #spi.
How will this plugin be useful in our scenario ?

Why is Heroku attempting to run newrelic-agent.jar instead of my app?

My app was working, it's working in staging, but after pushing that build to production, Heroku is running this command:
java -Dserver.port=12366 -javaagent:target/newrelic-agent.jar -jar target/newrelic-agent.jar
Why is Heroku trying to run newrelic-agent.jar instead of my app's jar?

Released v46
https://projectxserver-production.herokuapp.com/ deployed to Heroku
After re-deploying a few times, it started using the correct jar. Is Heroku picking up a random one?

Heroku tries to automatically figure out the command to run your app when it detects that you are using Spring Boot. However, since the new-relic JAR is in your target/ directory, it thinks that it is your app.
You can fix this in two ways:
Put the new-relic jar in a different directory (Heroku recommends target/dependency or similar).
Create a Procfile and explicitly tell Heroku the command needed to run your app.
If you create a Procfile it will probably look like this:
web: java -Dserver.port=$PORT -javaagent:target/newrelic-agent.jar -jar target/projectxserver-1.0.0-SNAPSHOT.jar
Then run:
git add Procfile
git commit -m "Procfile"
git push heroku master
You can see the logic for the default command in the Java buildpack's bin/release script.

Connecting to DynamoDB Local via Gremlin

I'm trying to get Titan with DynamoDB local backend running. I've followed the steps from github closely but can't get Gremlin to connect:

I'm new to dynamodb and titan so I'm really at a loss to work this out.

I was able to get gremlin running by following the Amazon docs for Installing and Running the DynamoDB Storage Backend for Titan.
You are almost there but mvn test -Pstart-dynamodb-local and mvn test -Pstart-gremlin need to run simultaneously.
So, after you run mvn test -Pstart-dynamodb-local you need to leave that running, open a separate terminal/ssh session, cd to the location of your git clone of dynamodb-titan-storage-backend and then run mvn test -Pstart-gremlin while the first command is still running:
/path/to/dynamodb-titan-storage-backend/# mvn test -Pstart-gremlin

Building Spark with Maven: error finding javac (but path is correct)

I'm trying to build a Spark 1.5.0 snapshot, on Windows. Firstly I ran make-distribution.sh using Cygwin (which pulled Maven etc). Now I'm running
mvn -DskipTests clean package
and getting this error, suggesting it can't find javac.

This questioner How to build Spark 1.2 with Maven (gives java.io.IOException: Cannot run program "javac")? had a similar problem - it was fixed by fixing the environment variables. I think mine are ok:

Shutting down zinc first should solve your problem. See the documentation here
./build/zinc-<version>/bin/zinc -shutdown

Another way is to change the pom.xml of spark and comment the line
<!--<useZincServer>true</useZincServer>-->
