Hi Antees,
I wonder whether someone got his own PropertyHelper installed and what needs
exactly to be done?
What I'm doing is basically this:
1. I'm deriving my PropertyHandler from `org.apache.tools.ant.PropertyHelper'
2. I wrote a `Init' task to install my propery handler. The execute method looks
like:
public void execute() throws
BuildException
{
PropertyHelper PH = new PropertyHelper(); /* that's my own here */
Project P = getProject();
PH.setProject(P);
P.addReference("ant.PropertyHelper",PH);
}
I can see that my methods are called, especially the method
"replaceProperties()"
of my helper. However, having done this I'm not longer able to resolve
${basedir}
and neither Java system properties
My build.xml looks basically like:
<project name="ant-test" default="test" basedir=".">
<taskdef name="my-init" classname="my.Init" />
<!-- install my property handler -->
<property name="X" value="Y" />
<my-init />
<target name="test">
<echo> basedir=${basedir} </echo>
<echo> X=${X}</echo>
</target>
</project>
This would echo then print
basedir=${basedir}'
X=Y
instead which is a bit unexpected to me.
Note that I can reproduce this with a very basic PropertyHelper:
public class PropertyHelper extends org.apache.tools.ant.PropertyHelper {
protected PropertyHelper() {
super();
}
}
Any help available??
Side issue:
Installing your own PropertyHelper is not enough in general. It appears that
task `Property' is not consistently using the PropertyHelper interface. In order
to have my fancy property handling installed I also had to subclass class
Property and make a couple of adjustments.
Finally - what is it all about?
I'm investigating build scripts written in our organisation. Lot's of times I
found
things like
classname = "x.y.z"
filename = "x/y/z.class
in build.properties. I want to avoid that users need to write things more than
once if not really required. So what I want to have is this:
filename = ${subst \\., /, ${classname}}.class # evaluates to: x/y/z.class
Everythings works fine so far except that my expression evaluator fails to
resolve ${basedir} :-(((
Thanks for any help,
Wolfgang.
