I upgraded to IntelliJ IDEA 11 CE and I cannot execute any tests or main programs within the IDE anymore. It is very strange as the JDK is there and will compile, but doesn't do anything when I go to run programs.
My projects are imported from a multi-module maven project and it has worked fine with previous releases.
How do I get it to run my programs and unit tests? I am having to use Eclipse instead to execute them.
It seems IDEA installation directory gets corrupted somehow. It happened to me unexpectedly after a week and the only thing I could do to re-enable run/debug was to reinstall IDEA from scratch.
Even invalidating caches or purging .IdeaIC11 directory didn't do any good.

I'm on Manjaro linux using Intellij Idea community 4:2022.1.3-1 and jdk 17 for this project, maven is also present
Intellij always hangs after it starts indexing the jdk, it's responsive for a period of time but if I type anything or open a new menu after it's begun indexing the jdk it will immediately freeze and I have to kill the process.
This behavior started after I began attempting to use the luaj-jse-3.0.2 library. I got it to successfully start by removing this library once but have been unable to replicate this since.
I have tried -
Reinstalling intellij
Installing a different version
Removing the luaj library (only successful once)
Deleting the .idea folder
Running intellij in strace
Waiting for it to resolve
Several combinations of all of the above at once
I'm really at my wits' end on this, anyone know anything?

Apparently maven was having an issue with the jar I imported through intellij as a library. On a new project without maven but with the offending jar and code copied and pasted from the original project it worked fine, I also got it to work by deleting the old project and importing it again from github without building any of the maven stuff and deleting all the maven files
It may have been my fault for configuring something incorrectly somewhere, but I was using the normal method to add a library in intellij so if that's the case whoops I guess
I am using Eclipse Mars and I have the following problem.
After the installation of a plugin, the Adoe Flash Builder plugin, it is a plugin that is installed outside Eclipse (executing an installer and selecting the Eclipse folder) I have some problem.
The plugin installation failed (because this plugin is supported only on the 32 bit version of Eclipse). So the plugin was not completly installed.
When I start Eclipse I obtain a lot of error messages caused by this failed installation and it is impossible to me work.
So I have tried to disinstall this plugin but it doesn't give me the possibility to uninstall it (the Uninstall button is disabled).
Here the screenshot where you can see that, selecting the plugin that I want to uninstall, the Uninstall button is disabled:
Why? Can I manually delete this plugin in some way? (I have not directory related to it into my Eclipse folder). It seems that in some way Eclipse have the information of this plugin but that this is not effectively present. How can I remove it? Or is faster reinstall and configure again my environment (Eclipse + SVN plugin + project configuration)
I have tried sometimes to get rid of "messed up" eclipse configurations.
In the end, it just didn't work out. I always ended up throwing away everything.
Besides: Eclipse Neon R2a was released already; so just download that and say goodbye to Mars.
And the real answer (in my opinionated eyes): I decided at some point to enable myself to install eclipse "from scratch" as quickly as possible (for example by having automation where possible; and "checklists" to follow where manual interaction is required). Simply because "installing from scratch" helps avoiding a lot of problems over time.
And while we are talking about eclipse best practices: if your OS is Linux, consider to switch to git-svn instead of SVN. Your machine still talks SVN to the remote SVN server, but you can enjoy the full beauty of git locally. No more SVN plugins, no more hours of waiting for that SVN plugin doing refresh ... I can't tell you how much time that simply change saved for me.
I've got a project setup in IntelliJ 13.1.4 which always worked fine (including tests), but suddenly I can't run tests anymore. No project settings have been changed since last tests ran, no additional tests have been added, all references in the tests work, the rest of the project runs fine and all tests compile successfully. I am kind of dry on ideas what the issue might be.
Class not found: "models.utils.ArrangementModelTest"
EDIT
I tried a checkout of an older version of which I am sure the tests worked (since I just committed a new test). But that version also doesn't work anymore :S
In the end the issue was fixed by a couple of steps:
Exit Intellij
Delete .IntelliJIdea13 and .IdealC13
I am using typesafe activator, run activator clean on project level
Delete intellij related files in project
Run activator idea on project level
Start IntelliJ
Re-install plugins, setup project, enz.
The culprit seemed to be the Play 2.0 plugin for IntelliJ
Try rebuilding the project and in eclipse i know, "clean project" it should help.
I've just installed Eclipse 4.2.0 and also imported all my old programs into it, except that when I run my programs, it pops up with a message saying:
Select what to run:
Ant Build: Launches an Ant Build with default
Ant Build...: Launches an Ant Build and allows it to be configured
This message has never appeared to me before. I wonder if it is because I imported my files incorrectly or something that I forgot to install. Please tell me how I can make it work properly again. Thanks in advance.
Ah! this is an issue I've experienced earlier. This tip solved the issue. Here's How to do it.
Make sure that you've built it. Or you can enable Project --> Build Automatically.
After the above option is set, try cleaning the workspace. Project --> Clean and clean all the projects you've imported.
Now restart eclipse and you can launch your program.
I have an urgent and puzzling problem with Eclipse. My system crashed on itself this morning, and after I rebooted, I can run a program perfectly within Eclipse, by right-click on the Java file and choose 'Run as Java Application'. However, after I make the project into a .jar file, and execute that, the behavior of the program simply does not reflect what the code does.
I have checked that I am compiling the right project, and running the same code from the same project within Eclipse does not cause any problem. And btw, I am using a plug-in called fat jar to compile the .jar file, if that makes any difference. I have used the same plug-in numerous times before to compile the very same project, and never had any problem.
Does anyone know what might be causing this weird/inconsistent behavior of Eclipse? Do I need to re-install Eclipse and fat jar to fix this? Thanks.
My usual procedure for strange things like this is,
A) Clean and build again i.e. Project -> Clean
B) (not so eclipse related) Since I am usually using a build tool, do the same thing from the tool to ensure its eclipse.
C) If it gets really bad, I'll start a new eclipse workspace and try from there.
D) Iff I had just installed a new plugin before things went strange I'd think about reinstalling
It sounds extremely strange :)
But Eclipse can, and has, acted strange before. I have had problems in both Java, C++ and PHP development during the years that could only be fixed with a resinstall of Eclipse. You could probably fix it by digging around, but the time it takes to find and fix these types of strange problems in Eclipse is simply not worth it.
Good luck!
Please try to Reset Perspective first (Before reinstall eclipse)
Window->Reset Perspective.
