Upgrade Eclipse java compiler

Question

I started using Ant, that ships with Eclipse. It annoys me, that I get hundreds of warnings in the lines of:

[javac] warning: java\\io\\BufferedInputStr

Answer 1

Follow these steps:

1. Download last JDK and install it.
2. Go to C:/Program files/Java and delete the previous JDK.
3. Update your JAVA_HOME and PATH Environment Variables with the new JDK.
4. Open Eclipse and in Windows > Preference > Java > Installed JRE, set newer version here

If there is a broken link with a jar in previous JDK, Eclipse will notify you. I solved in this way the problem with tools.jar ant reference, but it is a general way to find the solution.
