I love Ant integration into Eclipse JDT – it provides smart editor, handy auto-completion, and the most important – fully functional debugger.
Recently I have been laboring on porting a deployment system from shell scripts to Phing, a loose PHP port of Ant. And naturally, I miss the above. I still get a little aid from Eclipse – since Phing’s syntax is very close to Ant’s, I can at use Ant editor for Phing files to enjoy property navigation and target integrity validation.
I would be more than happy to announce that I’m going to fill the gap and implement Phing plugin for Eclipse PDT, but unfortunately – I’m too busy and too lazy. On the other hand, if you, my dear friend, will suddenly decide to accept this challenge, I can gladly invest my time in architecture, design, review & testing free of charge. :) Or should I anyway try to start it myself?
Got the Programming in Scala eBook. I hope to get time and build an experimental Eclipse Plugin with it.
I’ve just failed to install JDT over clean Eclipse Platform RC1 (and this time a bug has been opened):
An error occurred while installing the items
session context was:(profile=PlatformProfile, phase=org.eclipse.equinox.internal.provisional.p2.engine.phases.Install, operand=null –> [R]org.eclipse.ant.ui 3.4.0.v20090504, action=org.eclipse.equinox.internal.p2.touchpoint.eclipse.actions.InstallBundleAction).
Error while loading manipulator.
Error while loading manipulator.
Retrying causes the message immediately. Reverting to the previous installation stage does not help. Restarting does not help either.
It’s very sad that what they call Release Candidate is still rare. Waiting for the release…
Honestly, I was pretty unsure regarding Maven at all. “Why should I port my projects from Ant, where everything is plain, simple and predictable? Single point integration jars are connected to their dependent projects, shared ones are extracted to a Libraries project. Deployment is as easy as checkout and build…” – I convinced myself.
But soon I’ve realized that if our team’s Product is no more than a chain in the string of Products and Components which are unified into the Solution, than why the hell should our code base not to be like that? It’s so nice that lots of Environments has their packaging systems which make installation simple and aesthetic… So if you work in Java and harmony and beauty are not just senseless terms for you, believe me, you should use Maven.
The main Maven’s advantage over Ant is that each dependency, called artifact can be (and commonly is) an independent project with its own history of versions and dependencies. So, if you want your project to be dependent of any library, you can just find it in one of major Maven repositories, add its id to your pom and – voila! it works.
Then, when time comes to deploy your stuff, you pack it and do the same – upload your stuff to another maven repository. Here the cycle closes and the universal happiness has been achieved.
Now, regarding the subject. There are 2 Maven Eclipse plug-ins in the market – m2eclipse and q4eclipse. Both of them recently were accepted as Eclipse native incubation projects as M2E and IAM. I tried them both starting from the second, but as it always happens, the first was the better one. M2E is very stable, comfortable and easy to understand w/o any documentation, while IAM is pretty buggy and unclear.
So I chose M2E to work with and it took just about 3 hours to convert all my projects to poms, configuring all their dependencies and then converting the projects into Maven managed ones. With the last action, all the Eclipse dependencies convert into Maven dependencies, the build is replaced with Maven build and it guarantees that there will be no surprises in production builds. And then you can proceed with LB/Continuum/CC with no time spent to understand why nothing doesn’t get built correctly.
Now what’s remaining is to reintegrate the changes from the sandbox branch and help the team to not be too scared of the changes :)
