I'm trying to build a project using ant but I keep receiving this error on issuing ant clean:

Unable to locate tools.jar. Expected to find it in /usr/lib/jvm/java-7-openjdk-amd64/lib/tools.jar

I've tried to change JAVA_HOME to point to JDK and exported PATH variables, but still to no avail. Here's what they look like: 

export PATH="/usr/local/heroku/bin:$PATH"

export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64

export PATH=$JAVA_HOME/bin:$PATH

Here's what my /etc/environment file looks like: 

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/$
JAVA_HOME="/usr/lib/jvm/java-7-openjdk-amd64"

As mentioned by OscarGz in the comment, you should be able to find your answer in Ant needs tools.jar and unable to find it.

Short summary: Install the JDK (Java Development Kit) with the matching version. In Debian-based systems, the package may be called openjdk-7-jdk (or later versions). You might also need to set the Java version which is actually used by invoking the update-alternatives tool for java and javac:

update-alternatives --config javac
update-alternatives --config java

Manually setting environment variables should then not be necessary.
