Set up Jenkins to run a specific maven command - maven

I’m new to Jenkins and currently working on a maven project.
I am able to run a simple Jenkins job using maven commands.
mvn clean install
However, the extended requirement requires me to us an additional parameter in the maven command
mvn clean install -DfileName=file1
Is it possible to have a drop down with file names (e.g. file1, file2 ..) and have the user selected one append to the maven command.
mvn clean install -DfileName = {selected filename from dropdown}.
Could some one please assist with this along with what plugin and how can I setup.

Parameterize your jenkins job see https://wiki.jenkins.io/plugins/servlet/mobile?contentId=34930782#content/view/34930782.
Use choice parameter to add your file name choices
Active Choices Plugin - https://wiki.jenkins.io/display/JENKINS/Active+Choices+Plugin
The user selected choice can be used in your maven command using "{params.param_name}".

Run mvn command on module from existing source

I imported several maven modules on IntelliJ IDEA by using the option File/New/Module From Existing Source. This is working fine but I'm not able to run mvn command lines on one specific module by its module name.
I was able to do it by specifying the path to the pom.xml file by using -f option:
mvn -f "path/to/pom.xml" clean
But I would like to avoid having specifying the path every time I want to run a mvn command. Is their any way to run the command by specifiying the name of the module ?
Thank you.
If you use "Run Anything" then it's possible to select module at the top right corner
You can perform maven install, maven clean etc for a complete module or sub modules of a project using top right option in IntelliJ.
Maven-->select module/submodule folder-->Plugins-->select the option:- deploy, compile, install, clean etc.

Where does Jenkins store the project source

I have a Jenkins job that uses a script to build my project. On the following line, the script fails mvn -e -X -Dgit='$git' release:prepare.
Because I want to search for the cause of this, I want to go to the Jenkins server and run mvn -e -X -Dgit='$git' release:prepare from the command line, to see if it works.
Does Jenkins store the projects' source code somewhere, such that I can go to that folder and call Maven?
If yes, then where?
Yes, It Stores the project files for the job by default at
/var/lib/jenkins/workspace/{your-job-name}
This is where jenkins suppose the project files to be present or it pulls it from a source before start working/building from it.
Quote from Andrew M.:
"Hudson/Jenkins doesn't quite work that way. It stores configurations and job information in /var/lib/jenkins by default (if you're using the .deb package). If you want to setup persistence for a specific application, that's something you'll want to handle yourself - Hudson is a continuous integration server, not a test framework.
Check out the Wiki article on Continuous Integration for an overview of what to expect."
From this Question on serverfault.
This worked for me:
/var/jenkins/workspace/JobNameExample
but, if your build machine (node) is a different than the one where Jenkins is running (manager), You need specify it:
/var/jenkins/workspace/JobNameExample/label/NodeName
Where you can define label too:
jenkins stores its workspace files currently in /var/jenkins_home/workspace/project_name
I am running from docker though!

How to Build a maven project using script file?

I have created a maven project in STS.I completed the development and testing code for my project.If now I want to run or build this project, then I have to do the following
Right click on the project-->Run as-->Run on Server (or)
Right click on the project-->Run as-->Maven Build
If I want to run the test code then
Right click on the class file-->Run as-->Run JUnit
But I want to create a text file I mean script file to run all these commands when I run this script file from the cmd prompt. I have found out on a web site that I should create a PowerShell file, So I don't cognize how to compose a script file like this, is there any example file for it ?
Please, anybody can help me
You can just run mvn clean install on your project root folder (i.e. where your pom.xml file is) in cmd prompt. This command will trigger your project default build lifecycle covering a number of build phases including:
validate
compile
test
package
integration-test
integration
verify
install
During these build phases, Maven will validate and compile your project, run tests (if any) against your codes, package the resultant binaries into say, a JAR file, run integration tests (if any) against your JAR, verify it, and then install the verified package to your local .m2 repository.
If you really want a script, then just add mvn clean install to your batch file.

Is there a way to set the Maven version number dynamically?

I would like to use Maven to produce an artifact in zip format. To give you some background; my project includes an APS package (Application Packaging Standard, used to provision cloud applications on the Parallels platform). This package is a zip file that contains a combination of XML as well as PHP files. It is generated by an APS plugin from within Eclipse and its name always includes the version and release number of its contents.
What I am trying to do is generate a zip file with Maven that would be kind of a release candidate that will be eventually sent to customers and would include not only the actual APS package but also other files such as README, User Guide.pdf, etc;. I would like the name of this zip file to contain the version number of the version number of the APS package. Currently I can generate this manually by using something like "mvn -Dversion=1.2.3-4 package" but I would like to automate the process and ideally run this from Jenkins.
Basically, my strategy is to run a script that would extract the version number from the initial APS package, once that is done, my script can invoke Maven and can pass this parameter to it so it can generate the final zip with the proper version number. This is fine but again, I need to run this script manually and I am looking for an automated process.
My question is; is it possible to invoke this script from within Maven and use its return as a parameter to set the version name (or the name of the file that will be generated) at run time? As I mentioned, I would like eventually Jenkins to handle this. It can pick up the pom file but I am not sure how it could kind of "auto configure" itself to have the proper version number.
Thanks is advance.
From jenkins build you can use profile with ${BUILD_NUMBER}:
<profile>
<id>jenkins</id>
<build>
<finalName>${artifactId}-${version}-${BUILD_NUMBER}</finalName>
</build>
</profile>
Then run in jenkins:
clean install -Pjenkins
I use the SVN (or any source versioning system) version to identify the software builds.
By simply executing this
REVISION=`svn info | grep '^Revision:' | sed -e 's/^Revision: //'`
on the sourcers folder you get the right value in $REVISION, then you can use it for your maven build
mvn -Dversion=1.2.3-$REVISION package
easy and clean

Which Maven goal to use as no-op (for scripting purposes)?

I have a script on Jenkins CI which optionally does dependency:go-offline. The other option should be to do nothing. But I can't put "" in there - it must be a goal.
So - which one would you pick? It should:
Be in central, always reachable
Take minimum time
Have minimal output
Have no side effects
I was thinking of some help:... goal but those tend to have a lot of output. Any better?
You can use this goal and option:
mvn --quiet help:help
the -q,--quiet option causes the output to only show errors.
Note that Jenkins allows you to add options like --quiet as diplayed in the usage: mvn [options] [<goal(s)>]. You configure these in the Jenkins job’s “Goals and options” field.
Check mvn --help output for further information.
I know this is an old question, but I came across it when I had the same requirement and it's still unanswered, so I'm posting for anyone who needs it in future.
This still depends on the current project, but could be useful if you don't want to hardcode a specific plugin for some reason:
mvn -pl ./ validate
-pl ./ means only current project, ignore submodules. Alternatively you could specify specific project by relative path or [groupId]:artifactId.
validate is the first phase of the Default Lifecycle. Doesn't change or build anything.
Alternatively, if you don't have a maven project at all, some maven plugins, or rather specific plugin goals, can be executed without it. E.g.:
mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:help
It would still scan projects if it sees a POM in the current directory. And of course you still need to have the plugin in your local repository.
