Your properties file will contain properties such as:
The ANT compile target then uses these properties:
However, the debug information is not there when you are debugging. You run
ant -v compile to get more information. You see:
Now, as we can see the properties are echo'd as expected. But, the "-g:none" indicates the compile won't include debug information. Before you tear your hair out, relax! You have just made a very silly mistake we all make at sometime. When ANT reads property files it reads all property values literally. This means there is a difference between "true" and "true ", i.e. boolean properties should not have trailing spaces otherwise they will not be read as boolean properties. This is what happened here. Ouch!
|Ouch - trailing space!|
As it states in http://ant.apache.org/manual/Tasks/property.html, regarding property files: "Trailing spaces are not stripped. It may have been what you wanted."
So rip that trailing space and re-run the ant compile target.
You should see:
which means the compiler is going to add lines, vars and source debug information. Happy debugging!
