NIOS Eclipse not starting for 18.1

[RShie]

My Eclipse Mars IDE was working yesterday. Today when I start eclipse it I get the error in the error log.

Uninstalling and reinstalling Quartus does not make this problem go way (It really should and it reminds me of my loathing for Eclipse)

So what do I do to fix this? 

[RShie]

So no answer? 

I really wish embedded platforms would stop using Eclipse.

Hi, Robin

May I know which Quartus edition you are using ?

There are requirements for your PC, you may refer to below:

Hi,

I get this error and just deleted the folder .altera.sbt4e from C:\Users\USERNAME\ and relaunch again Eclipse for Nios2, it worked.

Thanks 

[RShie]

Okay thanks for this. 

We have to use various embedded devices and one of those is Netburner that also uses Eclipse. I had the same problem with that too.

In the end I managed to track down what I believe to be the problem. We also use dsPIC digital signal controller processors from Microchip. Their MPLAB X IDE is also based on Java like Eclipse. 

If I keep MPLAB and Eclipse on separate machines the problem goes away.
