I have created run configurations ( maven clean install , skip test ) in eclipse of projects in my eclipse workspace. They needs to be executed in particular order one after another. I've to run them manually one after another. Is there any way I can automate this ? Click one master configuration to run all maven build tasks at once ?
Click one master configuration to run all maven build tasks at once ?
Yes, this might be a solution.
When a simple project starts a simple configuration is usually enough. But when the complexity increases you end up in a too long build, so you start realizing that you don't want every goal runs on every build. At this point you have to choose how to handle such complexity: in general two approaches may be adopted:
one project many commands : you might prefer keeping the project simple but with different goals / life-cycle phases / run configurations;
multi-module project one command: you might prefer splitting your project in a multi-module project, with each module dedicated to a specific task (testing, building site, jar/war-ing), so you can run the same command but on a different module.

I've been scratching my head a long time trying to figure out a solution to this problem but haven't come up with good solution yet, maybe somebody can help me with any suggestion or good practice.
Here it goes:
I have three git projects: compilerweb, compiler and common
The three projects point to the master branch in git
compiler and common are java projects and compilerweb is a java web project
I've setup three jenkins jobs to compile each project individually
The dependencies between the projects are as follows: (->) means depends on:
compilerweb -> compiler -> common
the compiler project is launched as a standalone project and also is used by compilerweb as a library
compilerweb has integration tests
What I'd like to do is to configure a continuous integration schema where any commit and push on any of the three projects launch a full build to ensure the
stability of the whole project but I'm not sure what procedure or strategy to put in place
What I tried first was the following:
If a push is detected on common, then compile common, then compiler and finally compilerweb that launch integration tests
If a push is detected in compiler, then compile compiler and finally compilerweb that launch integration tests
If a push is detected in compilerweb, then compile compilerweb that launch integration tests
But with this schema for example if a developer is working on the three projects at the same time, and then he executes a commit and push on the compilerweb project then a full build will be launched without his changes in common and compiler and the build will fail.
What is the standard way of implementing continuous integration when there are dependencies between the projects and all of them are pointing to master branch?
Thanks a lot for any suggestion or answer! :)
Configure one job to start another.
When common finish to build with success, start compiler.
When compiler finish with success, start compilerweb
You configure this in "Post build Action" >> "Build another projects"
Configure to trigger compiler job on push to any git repository.
This way, no matter where the push happens, every time you will run the 3 jobs.
You can add a delay to the jobs to avoid problems with commit and push on all the git repos.
Trigger job with delay
http://myjenkins/job/jobname/build?delay=15
Another approach is just run the build if the commit has or not a specific message. For this to work you will need talk with the developers.
If they are going to make a change that needs commit on 3 repos, start the build only on the last commit.
For example:
Configure the script to not start the build if the commit has the the word's "ON HOLD" in message.
I am trying to find a solution for the following puzzle. I have java projects, managed by maven, which needs some native dependencies to work (run unit and integration tests). Those are provided in form of deb packages, which needs to be installed prior to running a build.
I use Jenkins for CI. Native dependencies can not be installed on Jenkins nodes, because of conflicts with other builds and they can change often. What I do now is not to create a Jenkins job type 'maven', but 'freestyle' and use a pbuilder to create an clean sandbox, install all that is necessary and invoke maven build.
This is working great, but I am loosing Jenkins maven goodies like automatic upstream projects, trigger build when dependency change, etc. Jenkins simply does not know that maven is there.
Finally, my question. Is there a way how to achieve both, isolate build so installed libraries does not affect other builds and leverage Jenkins's 'magic' applied to maven builds and their dependencies?
You could split your build in three jobs, which trigger the next one.
Create needed environment
Run maven job
Clean Up
Even a Freestyle job has "Invoke top-level Maven targets". You could use that to get "maven goodies" while also having ability to run other build steps.
There is an option to "use private Maven repository" which will make sure it will use the .m2/repository folder location relative to the workspace. If you need to separate into multiple jobs, you can use "Custom/shared workspace" between those jobs.
Even in Maven-style job, there is an option to use private repository, so that one job does not affect another.
The problem can be solved by using distributed Jenkins builds. Slave agents can be configured to provision clean environment (e.g. via VMs, docker,...) for each build and tear it down after build is done. This way Jenkins job can be of Maven type and any changes done by pre-build step will not affect others.
More information can be found here.
Consider docker. There you can run processes in isolated environments just as you want. Docker works in a way that it easily communicates with Jenkins.
As a benefit you can also use that docker container to run local builds in the same environment as they run in Jenkins.
I am using Jenkins for continuous integration win my scala application. I have two modules in every project. One for Scala and one for UI (Angular with bower and npm). Sometimes, in the UI project, some of the commands are not getting executed properly. However, if I clean the jenkins workspace and run again, it works fine.
I am looking for some plugin or another solution by which the workspace can be cleared before every 10th build or so.
Using Workspace Cleanup Plugin , it is possible to clear the workspace before/after build. But then the build takes more time to complete since many files/jars needs to be downloaded
I have a multi-module maven project and looking to leverage the parallel build feature in Maven 3. But some of the modules lay the groundwork for future modules (when built sequentially, like creating some directories, downloading some non-maven jars etc). Is there a way for me to control the parallelism partially so that the build starts of sequentially and then goes parallel and eventually converge to a final module that does aggregation and cannot be run before the others?
Thanks in advance
Just add a dependency on the pom (pom) we use this to order our docker builds (images depend on base images that need to built earlier)
I haven't tested this, but I think it should be possible. The downside is you will have to control that branch/join logic yourself by running mvn multiple times.
First, check out this article for how to do parallel builds: https://cwiki.apache.org/confluence/display/MAVEN/Parallel+builds+in+Maven+3
Now when it comes to building individual modules, you should use this command line option:
-pl,--projects <arg> Comma-delimited list of specified
reactor projects to build instead
of all projects. A project can be
specified by [groupId]:artifactId
or by its relative path.
I think you will need to run the mvn command multiple times. Let me know if you need more info.
Side Note: Consider this line
This build-mode analyzes your project's dependency graph and schedules modules that can be built in parallel according to the dependency graph of your project.
You may not need to do any branch/join logic. See if it works without it.
We want to use Hudson/Jenkins to build our project which is currently realized entirely in Eclipse. From what I can tell, there are various ways to go from A to B, or E to H, as it were: export as Ant script, export as Maven script, export as Runnable JAR while creating an Ant script for that, etc.
All of the above seem to have in common that between "This runs in Eclipse" and "Hudson produces something that runs" there are multiple steps which are independent, for example, you can change your project, commit to SVN and trigger a Hudson build, but unless you specifically remember to "Export as Ant Script" in between, it will fail.
Is there a "one in all" solution ? I'm not worried about the amount of clicks, but instead about the various steps in between that, to make matters worse, are only needed sometimes. In short: I am looking for something that goes from "I can click on the 'Run' button and it works" to "Hudson produces something that works" without every developer having to remember every optional step in between.
Ideas ?
Edit: All of the answers so far seem to suffer from the same issue: it's all parallel development. You have your Eclipse Run Configuration, and you have Maven/Ant/Whatever build. If you change your run config, you have to then remember later to change your Maven/Ant/Whatever build, commit it, and then HOPE that all other developers notice the change to the Maven/Ant/Whatever build during their daily SVN Update, manually open the file, inspect the changes and then duplicate those changes in their own run configs. That seems like it's just begging for bugs and mistakes, isn't there anything that's properly integrated with the Eclipse Run Configurations ?
Hudson can build Maven or Ant projects, so the first step is to get a reproducible build with either tool, which you only need to set up one time. Then you need to take that pom.xml or build.xml file and actually commit it to Subversion. This is necessary since Hudson won't open Eclipse and will instead use the command-line to execute a build.
Then you can setup a new Hudson job that will watch Subversion for any changes. Your developers can use their normal workflow, where they use Eclipse to do builds and commit changes to source control when they're ready. Hudson will see it and pull down a fresh copy of the code base, and then will do its own compile and will report back any problems.
Personally I prefer Maven2, since I know Hudson has solid integration with it and will do things like run your JUnit tests. Eclipse used to be painful with Maven, but now there's the m2eclipse plugin.
I'd try http://www.ant4eclipse.org/.
It allows you to build your eclipse project from an ant file. From the first paragraph here: http://www.ant4eclipse.org/node/6 it sounds very much like what you want. With ant4eclipse ant will access your eclipse project and then it should be able to build through Hudson.
The aim of the ant4eclipse project is to avoid (or at least: to reduce) the redundancy of Eclipse and Ant configurations. More precisly: it consists of Ant tasks that are able to read and work with some of Eclipse's configuration files.
Migrating to Maven, Hudson has great first class intergration with Maven.
Maven 3 + Archiva makes a very potent build system. Of course there are other Repository Managers but Archiva does just enough for what I need.
Once you get Maven, you really wonder how you did without it up until then. A dedicated private Repository Manager helps this greatly, that is why Archiva is important to the mix.
