Java Solutions
Solution 1 - Java
File
| Invalidate Caches
is the first thing you should try in case of such issues.
Solution 2 - Java
Select your modul in the "Project View" and press F4 in the "Project Setting"select "Module". In the "Module Settings" overview you can add/remove the Modul SDK.
Solution 3 - Java
Following this worked for me :
Select your module in Project View
Press F4
Go to SDK
Select you SDK
Make sure you have various jars in there. Else, select proper directory.
In my case, even though correct directory was selected classpath,sourcepath etc were empty.
So I had to select jdk installation directory one more time, which loaded all the jars and solved the problem.
Solution 4 - Java
In my case just File | Invalidate Caches
and Restart
did not work. Upon Right clicking the project and going to Module Settings
, I had no SDK selected under Project Settings->Project
.
Solution 5 - Java
I followed below steps
- Press F4
- Select Modules in Project Settings
- Set up Module SDK from the drop down or add the new one.
- Apply & OK
Solution 6 - Java
For someone like me, looking for a way to setup an offline documentation in IDEA on UBUNTU Linux. You should install the openjdk-8-doc (or openjdk-X-doc in general case) package, then go to File
|Project Structure
|SDKs
|1.8
(still 1.X
in general), then select tab Documentation Paths
and add the path /usr/lib/jvm/java-1.8.0-openjdk-amd64/docs/api
there.
Note, that path of Java docs installation may differ on your machine. You are able to check the path of Java docs installation executing dpkg-query -L openjdk-8-doc | less
in a shell.
Solution 7 - Java
I was seeing this exception in the console:
NoClassDefFoundError: com/intellij/remote/RemoteSdkConnectionAcceptor
which was caused by the python community edition plugin on Intellij IDEA 2016.2.5.
After updateing/disableing the plugin, I was able to setup the SDK again.
