IDE nor working

[pearl lintel]

Hello,

I use IntelliJ IDEA. It stopped working recently. It wont give me auto-completion, auto-imports or ANYTHING a normal IDE does. NOTHING. It is just a text editor. What am I doing wrong!?

unintelliJ is bad ide

use eclipse

[compact carbon]

Try File -> Invalidate Caches & Restart

[fierce lynx]

Check your project settings if a JDK is selected

[pearl lintel]

17.0.6

[pearl lintel]

Done

No result yet : /

can you share your project structure

[pearl lintel]

I wrote the question into my course's forum and someone said I have to ONLY import the folder where the gradle files also are, otherwise the IDE doesnt know its a java program

Is that right?

[compact carbon]

if you show me your project structure I can tell you more

[pearl lintel]

Do you mean this?

[compact carbon]

sorry I meant your file tree, on the left side of your screen were all the classes are located

[compact carbon]

does building the project work ?

[pearl lintel]

In this case I CAN actually create java-documents in the java file. But like this it doesnt work:

[pearl lintel]

Yes

[compact carbon]

here intelliJ should work as expected and the auto completion should work.

[compact carbon]

Here you aren't setting the source path. In this case autocompletion does not work

[pearl lintel]

So I ALWAYS have to be in a folder where there only is src/main/java for classes?

[compact carbon]

No, you can set your own source directories. Could you share your build.gradle file.

[compact carbon]

is any folder marked blue in this project ?

[pearl lintel]

Except the small blue block in the gradle folder no

[pearl lintel]

build.gradle:

id 'java'   
 id 'application'
}
application {    
mainClassName ='Telefon'
}
repositories {    
mavenCentral()
}
dependencies {    
implementation group: 'com.google.guava', name: 'guava', version: '23.5-jre'
}```

[compact carbon]

Are you trying to "combine" multiple projects here ?

[pearl lintel]

Kind of, yes. I get a few tasks each week, so I make a folder for each week

[compact carbon]

Ah yeah, don't do that in IntelliJ this does work in Eclipse, having multiple projects in one workspace, but in IntelliJ I would just create a new package per week, except of course the build.gradle changes.

[pearl lintel]

Well, I am putting the tasks for a week in one folder. Isnt that a package ?

[compact carbon]

well theoretically yes, but a package is a folder inside the source folder. Right now you are copying the entire project, including folders like .idea and build which are unnecessary.

Create a new Project and let IntelliJ configure gradle for you. You can add dependencies later but the important part is that you only copy the actual source files into the source folder, inside a new package for example.

[pearl lintel]

Thanks! I actually never made a project in IntelliJ itself but always cloned all files from GitHub
