Building older NetBeans project in bash leads to error

I am opening an older NetBeans project and I want to build it using ant in bash with debian. However, when I try to run ant, I get this error

BUILD FAILED /home/karelbilek/NetBeansProjects/oldProject/nbproject/build-impl.xml:528: The following error occurred while executing this line: /home/karelbilek/NetBeansProjects/oldProject/nbproject/build-impl.xml:261: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not point to the JDK. It is currently set to "/usr/lib/jvm/java-7-openjdk-i386/jre"

What does that mean? What should I do? In "/usr/lib/jvm/java-7-openjdk-i386/jre" there seems to be an actual JRE when I look there, so what is the problem?

You're pointing to a JRE (Java runtime environment) but not a JDK (Java development kit).

Only the JDK contains the compiler (javac). The JRE is used for running Java programs but doesn't carry the extra components of the JDK (compiler etc.)

it happened for me and i got through it by installing the jdk

sudo apt-get install openjdk-7-jdk

After installing jdk, the classpath executed right
