I have a bunch of Maven projects building in Hudson with Sonar sitting in the side-lines. Sonar gives me Sonar stats, FindBugs stats, and code-coverage.
I've noticed that regardless of if I use Sonar or if I use EMMA via Maven directly, the entire build cycle runs twice. This includes init (which in my case, reinitializes the database -- expensive) and unit tests (a few hundred -- also expensive).
How can I prevent this? I did a lot of reading, and it seems like this is due to the design of code-coverage plugins -- to keep uninstrumented classes separated from instrumented ones.
I've tried configurations like:
Maven runs: deploy, EMMA
Maven runs: deploy; deploy to Sonar on completion
The sonar documentation recommends running the sonar plugin in 2 stages:-
mvn clean install -Dtest=false -DfailIfNoTests=false
mvn sonar:sonar
The tests are bypassed in the first phase and run implicitly in the second stage.
A one line alternative is to run the following command:-
mvn clean install sonar:sonar -Dmaven.test.failure.ignore=true
but this will run the tests twice - as you have found.
To add to #Strawberry's answer, you could reuse the unit test reports instead of running them again. Refer to the section Reuse existing unit test reports in the sonar documentation
Once this is done, you can configure the following in Hudson
clean deploy sonar:sonar

I have a jenkins job to build my project run tests and then run sonar with sonar jenkins-plugin.
but when tests failed sonar analysis skipped.
You can trigger Sonar Analysis as a build step and not a post-build step. Take a look at this.
But my question is, why you should want to run a quality analysis for a project failing its build?
You can use flexible publish plugin in Jenkins.
https://wiki.jenkins-ci.org/display/JENKINS/Flexible+Publish+Plugin
As a post build action, use Conditional action to "Always". Whatever be the previous step result, the action would be run. Select sonar analysis as the action.
I installed Jenkins on my build machine and in the Jenkins config checked the box to run sonar analysis on my maven based project. It works but if I look at the log my entire project is built twice. Once from maven and once for sonar (still using maven). Any idea what I am doing wrong here?
Sonar analysis is performed through a maven plugin. So, whenever you start a sonar analysis, maven will run through all phases that come before the sonar phase, meaning that it will also run the compile and the test phase.
This means, if you want to do a Sonar analysis, you can make a Free-Style Job in Jenkins, configure no Build Step, and only activate the Sonar button. That should work, and should only build your code project once.
I have a job in Hudson server A which builds an artifact and deploys it to Nexus. I have another job in a completely separate Hudson server B which needs to download the artifact and deploy it. This job is normally run manually, and the person running it needs to indicate which version of the artifact to deploy - they may not always want to deploy the latest version (e.g. to roll back to a previous known good version).
Currently, I achieve this by using a parameterized build, and require the user to pass in the artifact version number; the job then uses the Execute shell build step to run wget on a URL constructed using the parameter. This is error prone.
Ideally I'd like a plugin that lets the user browse the artifact versions in the Nexus repository and pick and choose the one to deploy, but I'm open to other suggestions. A plugin that also handles the download would be nice, but I can live without it as long as I can still get a string that I can use in shell commands.
I've looked through the available Hudson & Jenkins plugins around Maven style artifact repositories, but they all seem more concerned with pushing artifacts into repos rather than getting them back down.
I'm using Hudson's "Copy Artifact" in other jobs, to get artifacts from other Hudson jobs on the same server, but this doesn't work across different Hudson servers, which is why I've turned to Nexus (which we're already using anyway).
Does anyone have any suggestions?
I recommend using rundeck to execute your deployments.
There is a rundeck plugin for Nexus that enables rundeck to display a pull down menu of available versions in Nexus.
There is a rundeck plugin for Jenkins that can be used to invoke deployments using rundeck and kick-off post deployment jobs (like integration testing) inn Jenkins.
I'm using NetBeans and GlassFish 3.0.1 to create an EJB3 application. I have written a few Unit Tests, which get run via JUnit and make use of the embedded GlassFish. Whenever I run these tests on my development machine (so from within NetBeans), it's all good.
Now I would like to let Hudson do those tests. At the moment it is failing with lookup failure on a resource (in this case the datasource to a JPA persistance unit):
[junit] SEVERE: Exception while invoking class org.glassfish.persistence.jpa.JPADeployer prepare method
[junit] java.lang.RuntimeException: javax.naming.NamingException: Lookup failed for 'mvs_devel' in SerialContext
After searching around and trying to learn about this, I believe it is related to the embedded GlassFish not having been configured with resources. In other words it's missing a domain.xml file. Right?
Two questions:
Why does it work with NetBeans on my dev box? What magic does NetBeans do in the background?
How should I provide the file? Where does the embedded GlassFish on the Hudson-box expect it?
Hudson is using the same Ant build-scripts (created by NetBeans).
I've read this post about instanceRoot and the EmbeddedFileSystemBuilder, but I don't understand enough of that. Is this needed for every TestCase (Emb. GF gets started/stopped for each bean-under-test)? Is this part of EJBContainer.createEJBContainer()? Again, why is it not necessary to do this when running tests on NetBeans?
Update
Following Peter's advice I can confirm: when running ant on a freshly checked out copy of the code, with the same properties as hudson is configured, the tests get executed!
10-1 it is a classpath issue as IDE's tend to swap paths in and out depending if you run normally or unittests.
Try running the tests on a commandline from a freshly checked out version from your SCM. Chances are you'll have the same error. Debugging on your local machine is a lot easier than on a remote machine.
When it builds reliably on the command line (in a separate directory) then it is time to move to hudson.
It is possible to take the source code directly from a svn repository and analyze it with sonar? Or configure sonar just to run a Checkstyle or pmd plugin for certain sources?
I need to do this on non-maven projects.
Sonar can run without maven entirely. Now there's sonar-runner
Yes, you just need to write a maven or ant script to check out the latest from SVN first, then run the sonar:sonar command.
It looks like Sonar forces you to create a pom.xml file and install maven2, even for a non-mavenized project: http://docs.sonarqube.org/display/SONAR/Analyzing+Source+Code
(fyi - Sonar is dead easy with a mavenized project, but in any setup the key will be in getting in the habit of looking at and using the results of Sonar to improve development. That's the hard part.)
