Call an ant build file from a java file?
Is it possible to execute ant build files from a java source?

Another option would be to use the 'variable' task from ant-contrib.
'variable' is used exactly like a property, but is mutable.

Re: change to a property
Posted by "mail.laconiadatasystems.com" <we...@laconiadatasystems.com>.
Hello All:
Is there any way to change a property or variable from the default Datatype
of String
to Integer?
Many Thanks,
-martin

Properties are immutable so you can not change them once they are set. But,
you can specify the value multiple times so that only the first one will
take effect. You can specify the value of a property on the command line
(-Dprop=value). This will be the first setting of the property so no other
settings in the ant file will override it.
Or if you can't/won't specify it on the command line you may need some extra
code to determine which one you want to set in the ant file. You could test
to see if an environment var is set and use it or use a default value.
I generally use a three tier approach --
1. Set from the command line
2. Set from a .properties file loaded by the ant file (before any other
target gets control)
3. Set default value in the ant file

Subject: change to a property
I have a situation where a default value of a property should be overwritten
I was contemplating pegging the property to an environment variable but
couldnt find a working example Does anyone have an example of a property
which changes because of an environment variable change and how to implement
this ???

Yes, one quick place to look would be in the testcases
subdivision of Ant's
source--org.apache.tools.ant.BuildFileTest in
particular may give you a nice head start. Also you
should definitely read "Developing with Ant">"Using
Ant Tasks Outside of Ant" from the manual.
