I am currently thinking about the potential solutions for building and running a Jenkins Maven project. I am a Jenkins Noob and what I currently think of is providing a Maven Plugin that runs the project right after the build and test phase. This feels wrong... .
So my basic question is, is it possible in Jenkins to configure a process to build a maven project and execute it right away and taking care for not interfering with it by starting another process and rebuilding it since a change arrived.
If this is possible it would ease the task by omitting the "Let's write a Maven plugin".
What do you means by 'execute'? Your program is a jar? If you do have to deploy it, there is tools in Jenkins to deploy with the build phase. If not, I think you can always make a 'Post build' command like java -jar nameofprogram.jar
In Jenkins you can configure jobs to execute multiple Maven targets when the jobs are run. I don't know if this answers your question, but you should be able to accomplish what you want by using "post build steps" and trigger certain behaviour from there.

I have a maven project where I'd like to debug tests using IntelliJ. The problem is that when I select the test I'd like to debug IntelliJ first executes mvn install command in order to be able to execute tests against the most recent code, and after this executes the test and allow me to debug.
I have multiple problems with this:
the project contains hundreds of tests which takes 2-3 minutes to execute them. It is super slow especially when I need to restart debugging frequently
if my test compiles, but still fails I can't start debugging since it will fail the maven install part of the execution and IntelliJ doesn't kick off debugging
I haven't found any hints in IntelliJ's doc about how to manipulate the mvn install part of the debugging process
yes, I could start maven in debug mode in the command line and attach IntelliJ to it, but that process is very fragile and it is 2021... let me use the IntelliJ fully...
I tried to add a Before launch step like mvn clean install -Dmaven.test.skip=true, but it results that the test classes won't be compiled.
My question is how can I manipulate the whole Debugging process is IntelliJ, especially the maven install part? What is the good solution here?
I'm using TestNG and the user interface doesn't offer me any option to do manipulate mvn install part.
I was wondering if there is a way to determine whether changes were made to the project and run mvn install only in that case. Similar to this question but I am not very interested in incremental build - Ideally I would like the build command to do nothing if no changes were made in the project. Is this possible
Thank you for your help.
You are looking into time independence of your build.
Currently maven is not built to support that (time stamps in jars etc) so I would suggest using a CI server for this listening to your git repository. For Maven projects Jenkins is a good start.
What I want to achieve is as:
Build the maven project and push the jar to repo, using maven & jenkins.
Deploy the application, using script.
Run jmeter test cases and display test results in jenkins dashboard.
First jenkins build my project and push it to repo.
Then I have defined a post build step in jenkins to run script on remote server, this script deploys and starts my application.
Then I have created a post build action in jenkins to invoke top-level maven targets, to run mvn verify, which triggers the jmeter-maven plugin, which runs the test cases on my already running application.
Is this a good approach and if not please let me know a better way to do this?
Thanks in advance.
The bit that may be missing here is how Jenkins knows if the build should be marked as passed or failed? Even if jmeter-maven-analysis plugin execution did exit with zero exit code, it doesn't mean performance-wise the application is fine. It may be, but don't have to be. I came across that kind of concerns some time ago and provided a solution. Check project wiki for usage example and more information.
I'm using maven on both mac and linux to build a .war file for a website. I'd like to know the best way to automatically run a script that will deploy the website to the server after a build.
What I am currently doing is I have a deploy.sh script that will run
mvn -P<PROFILE> clean package
and will then do a bunch of ssh / scp stuff to copy the target/file.war to the web server and run a bunch of commands to start/stop tomcat - clean out the logs etc.
Problems
Although various stack posts say using $? is supposed to catch the error code from maven I have yet to get it working and if for some reason I have a bad maven build I have no way to detect it. I would not like to do all my deploy tasks if the build fails.
Options?
1) Is there a correct way to detect a bad "build" from maven and have my script abort (I guess i could check if the war doesn't exist ...??)
2) Is there a maven "plugin" that will actually handle this for me, and if so could somebody provide a small code example.
I would do two things in the shell script which calls Maven and the deployment commands:
test whether the WAR file exists before attempting to deploy it, as you suggest yourself;
save Maven output to a timestamped log file for reference.
You may want to consider using maven as the entry point to the deployment and let it call deploy.sh rather than the other way around. This way maven will fail the build if something goes wrong.
The Ant plugin should be able to help with this, take a look at the second example here. It allows you to run a script and fail on error if desired.
We want to accelerate our build pipeline for a multi-module Java web application, which roughly consists of
compile/code analysis
unit tests
integration tests
GUI tests
At the moment each of these build steps starts from scratch, compiling and building again and again, which costs time and means that we do not deploy the actual files to production that have gone through the tests. Is it possible to get Maven to not recompile everything on subsequent steps but instead run the tests against the previously compiled classes?
We are using Maven3 to manage our dependencies and Teamcity as a build server (7 at the moment, planning to upgrade to 8 soon). I have tried to set up a build chain, doing a
mvn clean install
on the first step and then exporting all the */target/ folders to the following builds. Then ideally I would only do a
mvn test
mvn integration-test
Unfortunately I have not been able to persuade Maven to do this properly. Either it compiles the classes again or produces errors.
Has anyone successfully done this kind of setup and has any pointers for me? Is this possible with Maven and is this even the right way to do things?
