Java – errors in eclipse are unprovoked

• Java

I'm building an Android application

I was working on my application today and suddenly I saw all the items in the workspace marked with errors I don't know what caused it. I can't find the wrong explanation anywhere

I use helios.com on Windows 7 I even tried to download eclipse again, but it didn't help

Today, I tried to integrate Facebook with my application Their tutorial asked me to try to get a Hesh key from the keystore In this process, I added a program named Java_ The environment variable of home and point it to JDK

I don't know if this is the cause of my problem, but I think it may be relevant

I really don't know what to do

thank you!

Solution

Try this In eclipse, go to project – > cleaning – > select "clear all projects" This should rebuild all projects
