Builds failing after upgrading to Java7, Missing Tools.jar and bad class versions

Question

I recently upgraded to Java7 on my Macbook Pro. I downloaded the JDK (not the JRE).

» javac version
javac 1.7.0_17

» echo $JAVA_HOME    
/Library/Java/Java         


        

Answer 1

I had a similar issue and found the answer in another thread:

Symbolic link messed up on OSX while trying to change the Java version

I set JAVA_HOME as follows:

export JAVA_HOME=/Library/Java/Home

and it's working now.
