Subject Re: Perform different target depending on *value* of property
Date Fri, 15 Oct 2004 13:26:27 GMT
I'm not sure how to work your suggestion into my script.

Let's say I have three different values of 'servername', "foo", "bar", and
"test", and three targets, "foo-upload", "bar-upload", and "test-upload".
That would suggest that my script should say:

<antcall target="foo-upload"/>
<antcall target="bar-upload"/>
<antcall target="test-upload"/>

How would I ensure that if the servername was foo, *only* "foo-upload" was
executed and not "bar-upload" or "test-upload"? Wouldn't I still need
something on the upload targets or the antcalls to ensure that only the
desired upload target was executed? If so, what would I need?

Betreff: Perform different target depending on *value* of property

I want to revise an existing script so that it does a different target for
each of several different *values* of a property.

For example, if the property, which is named 'server' has a value of "foo",
I want the script to execute a target called "foo-upload". If the value of
'server' is "bar", I want the script to execute a target called
"bar-upload". If the value of 'server' is "test", I want the script to
execute a target called "test-upload".

Actually, although the target names begin with the server name, that is more
convenience than necessity; it isn't critical that the target names start
with the server name so I don't insist on that.

I am running Ant 1.6.1 but would be willing to upgrade to a newer version to
accomplish this. I would also like to stay "pure Ant" if possible but would
still be interested in seeing solutions using optional tasks or ant-contrib.

I know that 'if' and 'unless' are the normal mechanisms for enabling
conditional execution of tasks but they only seem to work on the basis of if
a property is enabled or not, rather than on the VALUE of the property.
