I am experiencing an issue running Jenkins job using slaves.
The job is a Maven job, that updates code from svn and then build and run tests, this project runs well in both master and slave as a standalone project.
The issue is when Master launch this project in the slave, in that case I see:
...
Svn Update OK
Error: Maven Home c:\maven doesn't exist
Both servers have maven on that dir, and both servers are able to run the build without master/slave setup.
Finally,I solve this problem.
The reason of "Error: Maven Home c:\maven doesn´t exist" is that your slave node use the master`s maven setting . If the slave want to use its own setting , it has to override that.
Override the settings as follows:
System Management -> Node Management -> your slave setting -> Node Properties -> check the Tools Locations -> Add , then set the slave maven option,alias select "maven",directory write with the slave maven directory.
you can try it.
You need to invoke your top-level maven targets and set the goals and path to pom, for instance:
goals: clean install
Pom: /home/merbel/sth/pom.xml
Finally i solve this issue, it was very simple just we need to check the global configuration that in maven part we have given correct path or not as a maven home.
for example: in global tools configuration..>come down in maven home part
maven Name: M2_HOME
MAVEN_HOME: /opt/maven
like this we need to give correct path where maven was untar so after checking this try once.....
in most cases it works succesfully.....

I have few jars which I have installed in my local maven repo(in windows under user/.m2). While building the project from command-line it's perfectly downloading the jars and packaging it.
Now I have created a Jenkins job (mvn clean package) to do so, but while running the jobs it's not picking up those jars from local repo instead trying to download it from central repo.
I tried all possible solutions available in Internet but still no luck. Can you please how I can configure Jenkins so that it should download those jars from my local repo ?
I also tried :-
1. offline mode
2. gave local repo path in settings.xml
3. use of nexus/artifactory in not an option for me
Seems maven executed by Jenkins not used the settings.xml in your local
you can try to change the maven command/goal in Jenkins job configuration with one more option:
-f <your local settings.xml path>
you can copy the settings.xml to your source code folder for debug purpose, after prove it work, then consider how to prepare the settings.xml for jenkins job with below options:
Option 1 use Config file provider plugin
Click Config Files -> Add a New Config -> Maven settings.xml
Change name and set your xml into content field:
In your job configuration, click the Advance... button in Build Section, choose your added settings.xml as below:
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
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.
I have a plugin which can run either using a pom.xml or without (depends upon the version of the artifact we're building: new versions go without a pom. Strange, I know).
I want to have that plugin run in Jenkins.
But when creating a maven project, I have to set a pom (or as a default, Jenkins suppose there is one in the base folder given).
Question: Is it possible to configure Jenkins to not use a pom when there is none?
As per my comment, you should use a Jenkins freestyle project build in this case, in order to have more flexibility and avoid the default assumptions of a Jenkins Maven build.
In such a build, you can then configure a build step executing a shell or a Windows command (depending on the Jenkins server OS).
Indeed, in the Jenkins Maven build, a pom file is always required, as mentioned in the help support of the Configuration > Build > Root Pom entry
If your workspace has the top-level pom.xml in somewhere other than the 1st module's root directory, specify the path (relative to the module root) here, such as parent/pom.xml.
If left empty, defaults to pom.xml
In Jenkins's "Configure System", there is "Maven Configuration" where you can set the local installation of Maven. What's this for?
local installation means the local Maven installation on the Jenkins server, right? But most of time we build in Slaves.

You can also use the Jenkins master only configuration, and it is an option for this situation :)
It works also for slaves, if path is identical as in master.
To configure different path on slaves go to Manage Jenkins -> Manage Nodes -> node name -> Configure.
