I have an ant build target using csc:

<target name="compile">
    <echo>Starting compiling ServiceLauncher</echo>
    <csc optimize="true" debug="true" warnLevel="1"
             unsafe="false" targetType="exe" failonerror="true"
             incremental="false" mainClass = "ServiceLauncher.Launcher"
             srcdir="ServiceLauncher/Launcher/"
             outputfile="ServiceLauncher.exe" >

        <reference file="libs/log4net.dll"/>
        <define name="RELEASE"/>
    </csc>
</target>

When I run it, the following exception comes up:

csc failed: java.io.IOException: Cannot run program "csc": CreateProcess error=2, The system cannot find the file specified

However, it runs without the exception but never correctly builds the .exe file, when I manually add in an empty ServiceLauncher.exe.

How can I correctly build this .Net project "ServiceLauncher"?
