Since the configuration manager and update manager for eclipse 3.2 is devoid of nice options for REMOVING or DELETING all my plugins it can be cumbersome to deal with needing to get your plugins in order. Just getting your dependencies worked out can be a nightmare when you have installed one version too high than you needed depending on the jdk version you are developing for.
Other than trashing the files in the plugins and features directory (which sometimes works) what other options do we have in a M$ environment?
In the situation where you are using RAD 7 you have to deal with the shared SDP70Shared folder too which is a bit ethereal as well.
I want to see a fool proof way to clean house for regular eclipse 3.x, RAD, or any all in one package that will work.
Eclipse 3.2 has "uninstall" feature for plugins under Help->Software updates->Manage configuration.
Eclipse 3.4 has the same functionality under Help->Software updates->Installed software
You could do a complete uninstall of eclipse and use a custom eclipse builder like http://www.yoxos.com/ondemand/]1 to create a build with the base set of plugins you use. I don't recall how eclipse is configured in Windows, but in Linux there's usually a hidden project directory in your work space that you may want to remove just in case. I'm not sure if there's any registry settings you need to worry about though.
The best solution I have found thus far is to uninstall and rebuild from scratch. Sometimes you can delete files in the plugins dir and run CCleaner on the registry and that might fix issues but it is problematic depending on the situation. If there were an application that really could make sense of eclipse plugins everyone would use it but there isn't.
Though it's not recommended to manually remove plugins managed by p2,
I find a regular plugin cleanup greatly improves performance and postability,
especially if you have a master eclipse configuration copied and shared
with multiple developers. In that case it's better to just archive the
master eclipse install instead of relying on everyone to update their
configs in synch.

While trying to generate build we get some plugin dependencies. When trying to add them in .product file, It shows plugin version as 0.0.0 by default. We have a situation to add more than one version of same plugins.
We tried to manually change 0.0.0 to the required version from the dependencies. We are successfully able to launch the application. But while trying to generate a build we get some errors.We have the required plugins installed.
If anyone knows how to add different versions, the help is much appreciated.
Edit:
Image showing the problem
This is the problem we are facing
The solution we tried
We tried manually changing version number but creates error during build generation
I'm not sure that this scenario is supported by PDE Build, because it sounds exotic a bit.
You can try to use different features to introduce different version of bundle.
But I think that more promissing strategy will be to "align" your dependencies, i.e. in your case it is better to select the version of GMF that uses the right Batik version.
Otherwise sooner or later you will get "blocking" bundle with singleton:true in your dependency tree, as #greg-449 mentioned.
Also, please have a look at this question: Tycho | How to build multiple version of same plugin using tycho
See my answer there:
https://stackoverflow.com/a/62426443/9062163
In fact the details I mentioned in my other answer where the result of a successful integration of Sirius 6.0.1 in an Eclipse RCP based on Photon. The troubles came from the integration of Batik 1.7 and 1.6 in the same product, the latter version being forced by the GMF version I use. I also needed some batik plugins of versions 1.8.0 and 1.9.1 for other reasons.
Problem
I'm trying to create a Play 2.3.1 framework, because the lack of info on how to get started with 2.4.3. So much has changed apparently that the tutorials on youtube is useless and I can't get it to work.
Question
How do I do this?
I have tried to go to https://www.playframework.com/download#older-versions but all versions yield the same link to https://downloads.typesafe.com/typesafe-activator/1.3.6/typesafe-activator-1.3.6-minimal.zip
which installs the newest playframework 2.4.3.
Please say that someone knows how to do this?
Also, why should I bother using 2.4.3 > 2.3.1 if I'm only creating a simple mobile app w/database? Security reasons or just "easier"?
Same question for IntelliJ 14 > IntelliJ 13 ?
https://www.playframework.com/download#older-versions is the link you need.
When you're new to Play! it can be quite confusing so I think a bit of terminology is needed.
SBT - Scala build tool. This is a build tool that is baked into every Play! project but totally independent of Play! framework, ie. many Scala projects use this to manage their builds without ever using Play! It's just the Scala equivilient of a Maven, Gradle or Ant. Nothing special.
Activator - This is Play!'s commandline, like a build-tool++. It's commandline tool with a superset of the SBT commands clean compile etc etc, with Play! specific ones like 'new', 'run'. It actually just amounts to not much more than a script (.sh/.bat) which bootstraps SBT and some extra goodness for running play commands. In earlier versions like 1.x this command was named play. Version 2.x was a practically a re-write so you can ignore all related advice.
Play - the playframework itself is just a regular jar (and all its dependencies). It is declared in the project/plugins.sbt
So the reason all the download links point to activator-1.3.6 is because that is just the version of the commandline tool. This will default to latest: 2.4.x.
When you perform an activator new you get a choice of templates. If you REALLY REALLY want to use 2.3.x you could choose this template when prompted hello-play-2_3-scala.
But I don't suggest you do that because:
The documentation for 2.4.x is comprehensive and there are walkthrough guides, it won't take any longer than a youtube video.
There are bug fixes and new features in 2.4.x
2.4.x introduced dependency injection which means it will be harder to upgrade once you'ved developed everything in 2.3x.
Apart from dependency injection most stuff works the same in 2.4.x
Intellij:
Use 14. Play support is improving all the time. If you can use the Early Access Program and the latest version of the Scala plugin.
Don't run 'activator idea' - this is deprecated. File -> open project from Intellij should be enough.
another completely beginner question. I just went through two introductory courses in Java, and I noticed that Eclipse can also support development in other languages (which I didn't know). Does anyone know how to add other languages to Eclipse so that I can switch between IDE's, or do I have to have a completely separate installation of Eclipse per language?
In Eclipse, use the menu Help -> Install new software. Choose "All available sites" in the combo box, wait a moment and then you can explore some other available plugins and languages.
Depending on your version of Eclipse, you might also have a menu item Help -> Eclipse Marketplace. That one is even more comfortable, as it allows you to easily browse all plugins listed in the Eclipse Marketplace. You can also browse the marketplace in your browser and afterwards drag and drop interesting plugins from the browser to your running eclipse (if your version of eclipse is new enough).
Eclipse is a plugin framework......
You have two choices - fortunately the eclipse community saw fit to produce Eclipse in a range of products that will do 99% of what 99% of people want. These distros are good to go. You install them and start work. You can then extend them if you want, but they do all of the basics very well, reliably, out of the box. Installing more than one with eclipse is easy, they do not interfere with each other, and if one turns out to be broken, the rest are not affected.
The other option, is to extend the framework by adding the plugins you want. So you start with an Eclipse distro, and download and install plugins till the cows come home. In the perfect world, this would be the perfect solution. Its not a perfect world..... you have not installed all you plugins and Eclipse suddenly crashes........
Problems occur because sometimes
Plugins are buggy
Plugins are incompatible with each other.
Different plugins rely on different versions of another one
(indirectly incompatible).
Plugins don't work the way the rest of the tool does
There are just too many plugins to choose from - you don't need most, and the ones you need can be hard to find.
Adding more than a few (probably 1) plugin to Eclipse exposes you to these problems. This is not something for the novice or people who have job not involved in fixing Eclipse. if you have a real reason for it, like your a sadist, or it's your job, or you want it to be your job, to make a team of 100 Devs productive, then plugins are great, otherwise, download a pre-canned, tested, reliable distro and take advantage of the great work by the contributors.
I evaluate SOA products of wso2 for few weeks and there are some basic (and crucial to me) features which I cannot find/use or maybe it just does not exist. I want to make sure.
First of all, creating IDE support. As probably most of you know wso2 team delivers Carbon Studio which is quite a nice thing. Unfortunately when it comes to team work so often importing existing projects into IDE I hit a wall because:
1) If I use Distribution Project I'm required to commit .projects files which actually contains nature understand by Carbon Studio. It is acceptable but it is as well bad practice in my opinion.
2) If I use Maven then after import I'm going to loose project nature so plugins are not going to work without preparing .projects.
Am I missing something? I would like get rid of .projects and be able to use IDE on 100%. Is it possible? Can't it be generated or something. Normally plugins are trying to recognize file type and edit it with specified plugin. I understand that most Synapse configs (for example) are all XMLs but that is not a reason for me. Any way, does someone know some kind of solution?
Also Distribution Project cannot be build from command line if known maven repositories cannot deliver some artifact. I can write maven plugin to implicitly build each wanted artifact but it is not something I want to do if maven can do it for me. And I cannot use maven because after import I'll lose IDE features.
To me IDE is useless if I'm required to fix each project before actually importing it. Time is very precious.
The second important and unacceptable feature is importing jars into project when using, for example, generators. Why created project cannot be configured to use dependencies?

what is the developer studio version you use? From developer studio 2.0.0 there is a feature to import a carbon project. Then you don't need to commit the .project files.

I wrote two Eclipse plugins that work fine when I use Eclipse to run them in another instance of Eclipse. I'd like to distribute the plugins to a relatively small number of people for feedback and was hoping that the dropins folder would provide a quick and dirty solution. When I put the plugins in the dropins folder of my Eclipse installation (Indigo), I see the plugins listed with other plugins in the installation details. The UI contributions are missing and I haven't been able to find any error messages in the logs or otherwise.
As stated, I'm looking for a quick and dirty solution. I intend to build an update site in the future, but would prefer to invest time into that only after getting feedback on the plugins because this is a side project.
It sounds like your plugin is loaded, but isn't started. A 'quick and dirty' solution is to have it use the org.eclipse.ui.startup extention point so it is activated on startup.
Another possibility is that your UI additions just aren't activated for the perspective, which you can fix by running Window > Customize Perspective.
