Solved The type java.util.Map$Entry cannot be resolved.

Hey guys I've a Problem with my Plugin. I recieved an error in eclipse, and I tryed already to refresh, the file, but there wasn't any change.
Here is the Error :

The type java.util.Map$Entry cannot be resolved. It is indirectly referenced from required .class files


Here is my code:

What is wrong, I already read, that this is a Eclipse bug, how can I fix this?

Remove the import for hashmap? I dont actually see it used in here anyway.

 

Thanks, but didn't helped.

 

Add import for Map (?)

 

Why I don't need any HashMap

 

I thought you were using any Map.Entry on your code can you recompile and give the log error + the entire class mentioned on the error?

 

I just use the one class posted in the Thread.

Here is the full error Report:

I know this will sound weird... Use java 1.7 not 1.8... I bet it fi es your problem

The problem is your machine isnt compatible with java 1.8 and your plugin was coded in 1.8. I had the same problem when i upgraded to 1.8. I just made my IDE build and compile all projects using 1.7. Remember once you make it build and compile against 1.7 you need to do a clean build or the discrete files will still be encoded with 1.8. Just recently went through the same headache haha. Just got a diff error message in the end.

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Man, thanks so much!!
It worked for me, I just activated 1.7 and rebuilt the Plugin, as you said.
Thanks and greez.

Anytime glad to help.
