Ant needs tools.jar and unable to find it

Question

I am putting together a dev environment for a Java program and after the first try of my Ant build scripts I got this error:

Unable to locate tools.jar. Expected         


        

Answer 1

On Ubuntu I've fixed this problem by installing package

openjdk-7-jre-lib

tools.jar appeared after that.

(I know this is an old post, but comment in hope that it will be helpful for somebody lurking for answer like I was today.)
