Summary: properties are not expanded when using -propertyfile
Product: Ant
Version: 1.6.2
Platform: All
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P2
Component: Core
AssignedTo: dev@ant.apache.org
ReportedBy: whaefelinger@epo.org
Property expansion takes place when using <property> tag. Property expansion
does NOT take place using command line option -propertyfile. This problem has
been reported, amongst other things, as bug #18732. Comments added to #18732
indicate that this anoying behaviour of ANT is not a bug but a feature.
FEATURE ENHANCEMENT REQUEST:
ANT's behaviour regarding expansion of properties should be
a. clearly documented
b. consistent
EXAMPLE:
== build.xml ==
<project [..] default="default">
<property file="${config}"/>
<target name="default"><echo>src.dir=${src.dir}</echo></target>
</project>
== build.properties ==
root.dir = .
src.dir = ${root.dir}/src
Here are three example session to demonstrate how ANT behaves now. I simplified
the output a bit:
$ ant
src.dir=${src.dir} # expected output
$ ant -propertyfile build.properties
src.dir=${root.dir}/src # unexpected, root.dir has not been expanded.
$ ant -Dconfig=build.properties
src.dir=./src # expansion takes place when using property tag.
Just to clarify. This is how ANT s h o u l d behave:
$ ant -propertyfile build.properties
src.dir=./src
This should also work (of course):
$ ant -Droot.dir=. -Dsrc.dir=${root.dir}/src # Footnote 1.
src.dir=./src
Footnotes:
1. The example shown assumes that no shell variable expansion takes
place. Windows user may safely ignore this remark.
