Jenkins needs to know where your Maven is installed

Jenkins runs into error while locating "maven" folder, for Maven type project:
Jenkins needs to know where your Maven is installed. Please do so from the system configuration.
Just about the place where pom.xml location is to be mentioned.
As stated in the above answer, you need to set-up maven in Global Tool Configuration. Name your Maven & check the install automatically option. Jenkins will automatically install Maven before building the project
As mentioned in Bug JENKINS-34743, you need to set Maven Location in Global Tool Configuration = Jenkins initial page > Manage Jenkins > Global Tool Configuration

running maven build on jenkins slave not working

I am trying to setup a maven project in jenkins via freestyle option. I have set manage jenkins->configure system to set maven downlaod automatic. But, when I run the project on the slave where there is no maven isntall, it does not automatically download maven on slave and install as i expected. am i thinking something wrong here?
This is what I have done :
1. Manage jenkins-> configure system-> maven install automatically
2. create a new job and select freestyle project
3. in the build step:
scp pom file from master to slave machine
run maven from slave using this pom file
Here there is no maven installed in slave. But, i though because of step 1, it will automatically download maven on slave and install before running the build .
In your build step you need to "Invoke top-level Maven targets", select the Maven version you configured and trigger the job again.
if the installation you added is by extracting *zip and not from Apache you have a "Label" field that is co-related to the Label of the node you're running on. I always use Tools label on my slaves, so just make sure you have this label configured in the node itself.

Configure Maven installation in Jenkins per individual job

Is there a way to configure Jenkins to use specific Maven installation per job?
e.g.
Job A - Maven 3.3.3
Job B - Maven 3.3.9
Jenkins allows you to select which Maven installation to use per job. You can setup multiple installations of Maven, multiple settings configurations of Maven to be exact, through Manage Jenkins → Configure System.
Then to configure per job, in Jenkins, select your specific build job and choose Configure. From there, assuming it is a Maven project build, you should have option(s) under the Build section (might have to hit the Advanced button) where you can select the Maven settings for your installation you want.
khmarbaise's comment is very valid, though. Unless you have a very specific reason to downgrade Maven for a given job, your build shouldn't be too reliant on what minor versions of the build tool to use.
For newer Jenkins versions, management of Maven installations is placed here:
Manage Jenkins → Global Tool Configuration → section Maven.
Per job configuration: "Maven Version" dropdown placed in "Build" section.

No SCM option on hudson

I install hudson also git plugin for hudson. But in project configuration there are no SCM option.
What can be the problem ?
You may need to install an additional plugin for the source code management system you are using. Ex: http://wiki.hudson-ci.org/display/HUDSON/Subversion+Plugin

How do I run install4j in CloudBees using Maven?

I have Maven build projects in a local Hudson instance that I would like to port to CloudBees. Install4j runs as an executable on the host system. In my experience, this includes an installer and registering the license key via the install4j UI.
How do I configure install4j so that I can run this build in the headless CloudBees environment?
I have been able to set this up, and it is very straight-forward.
1. Upload install4j to CloudBees
CloudBees runs on Linux, so extract and upload the Linux TAR.GZ version of install4j to your private repository.
HINT: via FTP => https://{username}#repository-{account}.forge.cloudbees.com/private
This directory is accessible from all build projects via the path: /private/{account}
2. Update Maven settings.xml
If you don't already have one, you'll need to create a settings.xml file in the same private repository.
Further reading on how to create a settings.xml: How do I deploy to private Maven repo from CloudBees?
You'll need to add the "install4j.home" and "install4j.licenseKey" properties to a profile in your settings.xml file according to the Sonatype Documentation*.
HINT: "install4j.home" is something like "/private/{account}/install4j5"
3. Update project pom.xml
Again, following the Sonatype Documentation*, update your project's pom.xml with the necessary build steps.
