I have downloaded the official codename one demos from here : https://github.com/codenameone/codenameone-demos
I opened one of the projects ( such as KitchenSink or Dr.Sbaitso ) in IntelliJ by going to File-> Open -> Selecting a project folder (KitchenSink).
I get the following error if I try to run the project:
Exception in thread "main" java.lang.ClassNotFoundException: com.codename1.impl.javase.Simulator

Java HotSpot(TM) Server VM warning: ignoring option MaxPermSize=250m; support was removed in 8.0
Do I need to add some library files?Please share the process. Also, is there a way to automate this step(adding libraries) whenever we open a codename one project? For example, If I import an existing Android project, IntelliJ/Android Studio automatically configures it.
Thanks in Advance!
I suggest creating a new project with that name. Then copying the code from the demo. This will provide the libraries necessary to compile and the IntelliJ specific files.
Ideally we'll make this process simpler like we did on Eclipse/NetBeans but we currently don't have a dedicated IDEA plugin developer on staff.

As of today, when I try to run some of my programs in IntelliJ today, this message was shown:
Executing pre-compile tasks...
Loading Ant configuration...
Running Ant tasks...
Running 'before' tasks
Checking sources
Finished, saving caches…
Module 'Listen' production: java.lang.NoClassDefFoundError: com/intellij/DynamicBundle

13.04.22, 14:54 - Build completed with 1 error and 0 warnings in 4 sec, 39 ms
This line is printed in red: Module 'Listen' production: java.lang.NoClassDefFoundError: com/intellij/DynamicBundle
I don't really have too much of an idea where I should look for the problem.
It seems to not have anything to do with the project itself. I already created a new Project and created a Hello World-program, which resulted in the same error.
Remarkably, yesterday my IntelliJ IDEA version was updated to version 2022.1.
Runtime version: 11.0.14.1+1-b2043.25 amd64
VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o.
I have no idea either whether it has anything to do with the new version either.
I maintain another Project, which uses Scala language. That one is messed up even more:
Cannot process toolwindow sbt

I had the same problem after upgrading to Intellij 2022.1
For me, the fix came from Gen's answer. I also had an old Scala plugin, and just removed it as I'm not using it anymore.
If you are looking to upgrade it, go to File -> Settings -> Plugins. From there just hit Upgrade for the plugins you want. After that restart the IDE.
I found that Scala plugin was not updated and updating it to at least version 2022.1.13 fixed it for me.
I upgraded to Intellij 2022.1 and encountered this issue when trying to sync the old gradles projects that used to work for me :
Caused by: java.lang.NoClassDefFoundError: org/gradle/internal/impldep/com/google/common/collect/Lists
Cleaning the caches folder's content (Gradle_HOME/caches) resolved this issue for me
Make sure to also check that the SDK is correctly configured for your project (Java 17 by default) and the Gradle home is well specified in the Settings>Gradle section.
For info, I'm using Java 8 and Gradle 5.5.1 (yes I know :))
Just upgrade the Scala Plugin and its done!
visiting
scala plugin's page
and install it from there worked for me on ultimate version 2022.2.3
Recently I created a new project using IntelliJ IDEA and Gradle for dependency management. After resolving all the dependencies needed by the project and running it I get the following error:

The problem occurs only with the classes from the resolved dependencies (I tried it also with a simple main program using Cache from Guava). The class causing the error is the following:
#SpringBootApplication
public class Application {
public static void main(String... args) {
SpringApplication.run(Application.class, args);
}
}
All the fields are shown correct colour (annotations are yellow, nothing is red), IntelliJ has all the resolved dependencies in the External Libraries directory. I'm using the green "run" arrow to start the project.
When using gradle from the command line, creating a fat jar then everything works fine. I already tried "Invalidate Caches/Restart", pulled the project several times from the repository, cleared the gradle caches, removed all the dependencies by hand, tried to run it using the Community Edition, the Ultimate Edition, running older projects which already worked some time ago (and don't work now).
Could it be somehow related to updating IntelliJ IDEA to 2016.3.4, build 163.12024.16?
It's a known issue in IntelliJ IDEA that is specific to Gradle 3.4 and later versions:
IDEA-167412 Gradle 3.4-rc-1 changes compile dependencies to provided
original bug report in the Gradle project with more details
comment from the responsible developer regarding "Create Module per source set" option and how Gradle integration works in IntelliJ IDEA
It's already fixed in IntelliJ IDEA 2017.1 and 2016.3.6.
You can also use Gradle 3.3 or older as a workaround if you can't or don't want to update IntelliJ IDEA.
I had the same problem, getting the error below from a spring boot application which was working fine a day before. I am using IntelliJ 2020.3, Gradle 6.5.1. I suspect my repository might have been corrupted.
Caused by: java.lang.ClassNotFoundException: org.springframework.boot.SpringApplication
After lot of tries from my IntelliJ I tried bootRun (in the gradle tree you can find this under Tasks > application > bootRun) and it worked.
Setting gradle version to 3.3 corrected this issue.

I have been using IntelliJ CE for the past two weeks when suddenly I ran into problems running my unit tests within IntelliJ. My team uses Play Framework v1.2.5 and if I run the project from the command line, it compiles and runs fine. If I run the tests for the project in Eclipse Kepler, they work fine. Only when I run the tests in IntelliJ, I receive this Exception during startup:

That class is in the project, but not being tested. I've tried to:
play clean (delete the play cache)
play idealize (regenerate the IntelliJ project, re-import)
play eclipsify (regenerate the eclipse project, then import into IntelliJ)
From within IntelliJ, File | Invalidate Caches and Restart
Upgrade my JDK from 1.7.0_45 to 1.7.0_51
Upgrade to IntelliJ CE 13.1
Clone a new copy of the repo, re-import
I am on a mac, if that makes any difference. Anyone else experience this? Any suggestions for something to try?
EDIT: Same problem on my Linux dev machine.
I believe I found the solution. PlayFramework v1 has some issues with Java 7's verifier.
Adding -XX:-UseSplitVerifier to the jUnit Run/Debug configuration solved this issue.
I have a simple hybrid App for Android phones. I have a skin folder created for Android tablets. I create an HTML file under the android.tablet but if this HTML file name match the same name of the HTML file under common folder then Eclipse shows a pop up error message that says:

I cannot confirm this using Worklight 6.1.0:
Created new project and application, "test"
Added the Android environment
Add a skin to the Android environment, "android.skin"
Copied common\index.html to android.skin\
No pop-up
Changed the HTML a bit
Run As > Run on Worklight Server
No pop-up
Suggestions:
Try with a new workspace
Close Eclipse and follow these instructions to delete the wlBuildResources folder
