This is easy to explain and it is is the manal ;-)
Using the <ant dir="x"/> will set the basedir as a user-like property, which means that
it cannot be overwitten subsequently - i.e. it gets "frozen".
You need to use : <ant antfile="x/build.xml" inheritall="no"/> which will set basedir property
as a non-user-like property.

I have a problem w/ ant and subant that does not involve basedir being set ; in smartfrog.org CVS for people who are curious, but I havent checked this stuff fully in yet because it doesnt work.
Directory core/ at the base of things
<target name="diag2" depends="init" > <ant dir="${components.project}" target="diag2" inheritAll="false" /> </target>
Directory core/components/
<path id="component.path"> <pathelement location="${utils.project}"/> <pathelement location="${logger.project}"/> ... </path> <presetdef name="delegate"> <subant buildpathref="component.path" antfile="build.xml" inheritall ="false" inheritrefs="false"/> </presetdef> </target>
<target name="diag2" depends="init" description="diagnostics"> <delegate target="diag2"/> </target>
So we set up a list of sub projects, a preset to do the delegation, then invoke it for our diagnostics "diag2" target
directory core/components/utils
<?xml version="1.0"?> <project name="utils" default="default" basedir="."> <property file="build.properties" /> <echo>base dir ${basedir}</echo>
<property name="root.dir" location="../.." /> <!-- Import common stuff --> <import file="${root.dir}/common.xml"/> </project>
1. everything works in components cd core/components; ant diag2
init-common: [echo] In project logger
init-standard-output-dirs:
use-smartfrog-tasks:
init:
diag2:
[echo]
[echo] build file logger
[echo] base dir /home/slo/Projects/SmartFrog/Forge/core/components/logger
[echo]
2. everything breaks when called from the core
chamonix:components> cd .. chamonix:core> ant diag2 Buildfile: build.xml
init:
diag2:
init:
diag2: [echo] base dir /home/slo/Projects/SmartFrog/Forge/core/components

-------------------------
What is going on here? It looks like the basedir is being frozen at the destination for the <ant> call; the subsidiary <subant> call is running with the wrong base dir. Either I am calling subant wrongly, or something is going wrong. Note that I have inheritance turned off on both invocations
