Error: Could not find or load main class org.grails.cli.GrailsCli - grails

Question

I'm trying to start a Grails 4 application in Intellij, the project is configured with Java 8 and Gradle seems to be loaded correctly, but it gives me the following error:
error: Could not find or load main class org.grails.cli.GrailsCli
Is there any know method in which I can get around this problem?

Answer 1

First, check if the language level and SDK are correct (File > Project Structure > (Project/Modules) > Language Level)
From 360learntocode' blog post:
This might be due to the removal of some dependencies or libraries
from the application. Sometimes, while loading multiple applications
from IDE while downloading the library for a particular project other
libraries for another project might remove so this kind of error might
occurs for that project.
Let's first delete the build folder under the application.
Now, let's refresh the Gradle project. Here we are using IntelliJ
Idea, we can refresh the project as below
Image description:
Click Gradle on the right tab;
Select the project;
Click refresh.
After refreshing the project it will download the missing
dependencies. Then run the application which will resolve the problem.
We can also try cleaning the application.
If we are using the command line then type the following command to
clean the application.
grails clean
If we are using the IntelliJ idea then Ctr+Alt+G opens the command
window and use the following command.
clean
Now, re-run the app.
