I placed some system-outs in the parsing code.
The parsing is done by ProjectHelper2. Id is stored via AntXMLContext to the
"UnknownElement".
C:\projekte\apache-ant-svn\sandbox\script>ant
Buildfile: C:\projekte\apache-ant-svn\sandbox\script\build.xml
PH2.ElemeentHandler.onStartElement tag=echo taskname=echo
AntXMLContext.configureId element=org.apache.tools.ant.UnknownElement@1f89ab83
id=foo
PH2.ElemeentHandler.onStartElement tag=script taskname=script
AntXMLContext.configureId element=org.apache.tools.ant.UnknownElement@383534aa
id=null
main:
[script] PH2.ElemeentHandler.onStartElement tag=antlib taskname=antlib
[script] AntXMLContext.configureId
element=org.apache.tools.ant.UnknownElement@50cbc42f id=null
[script] PH2.ElemeentHandler.onStartElement tag=componentdef
taskname=componentdef
... more element definitions ...
BUILD FAILED
C:\projekte\apache-ant-svn\sandbox\script\build.xml:9:
org.mozilla.javascript.EcmaError: ReferenceError: "foo" is not defined.
