Hi all!
I have a problem echoing a set of properties to a specified file. I have a
number of properties which have a common prefix, but the exact number is
undefined, so these properties are selectable by a propertyset by I do not know
the exakt number.
The reason for this somewhat uncommon setup is that I have created a common
"base" file (common.xml) that is imported into other (project specific) build
files in my workspace. This saves me a lot of time and typing since my projects
have similiar setup. This base file has a target for creating a jad-file (a
sort of manifest file used in MIDlet development) which holds information about
a jar-file. The importing build files however holds some information about
midlets that is not known when creating the common base build file, and
therefore I have to be able to find these properties and print them in a
generic way, regardless of how many they are.
The target just looks like this:
<!--_________Creates the jad file for the project_________
<target name="create.jad" description="Creates a jad file for the midlet
suite.">
<echo file="${ant.project.name}.jad" message="MIDlet-Version:
${MIDletVersion}${line.separator}" append="true"/>
<echo file="${ant.project.name}.jad" message="MIDlet-Vendor:
${MIDletVendor}${line.separator}" append="true"/>
<echo file="${ant.project.name}.jad" message="MIDlet-Jar-URL:
${MIDletJarUrl}${line.separator}" append="true"/>
<!-- and on it goes for some more properties including my unknown
number of specific properties -->
</target>
The properties echoed (such as MIDletVersion etc) out are set by the build file
importing the base file.
At the end of this target I would like to echo out all properties with a
certain prefix. The propertyset I want to output can be created like:
<propertyset id="midlet_properties">
<propertyref prefix="MIDlet_"/>
</propertyset>
But how do I echo this propertyset to the specified file? I tried using
<echoproperties> (I know this might not be the intention of echoproperties).
That gives me some additional lines at the top of the file that I do not want.
I also tried using pathconvert but that really needs a path, not a propertyset.
Do I have to use foreach from ant-contrib? Are there any other (reasonable) way
to do this? Any suggestions are more than welcome right now.
Thanks,
//daniel
