[Bug 57072] New: ${user.home} doesn't work when reading properties
from a file with prefix and prefixValues="true"
https://issues.apache.org/bugzilla/show_bug.cgi?id=57072
Bug ID: 57072
Summary: ${user.home} doesn't work when reading properties from
a file with prefix and prefixValues="true"
Product: Ant
Version: 1.9.4
Hardware: PC
OS: FreeBSD
Status: NEW
Severity: normal
Priority: P2
Component: Core tasks
Assignee: notifications@ant.apache.org
Reporter: lhersch@dssgmbh.de
Created attachment 32096

build.xml
Run the attached build.xml.
The output you get is like the following.
test:
[echo] user.home = /home/lhersch
[echo] test.my.home = /home/lhersch
Change the build.xml and set prefixValues=true in the property-task.
Now you get an output like the following.
test:
[echo] user.home = /home/lhersch
[echo] test.my.home = ${user.home}
I have tested this also with ant 1.8.4. There is the same behaviour.

You can't. Not using the property task, at least.
The whole handling of prefixes in properties has been a source for several bugs
and we've had out share of backs and forths with incompatible changes while
trying to "fix" what isn't really fixable. What you want to do is most likely
the opposite somebody else expects and we'd break this other person's build
file.
What you want to achieve can be done with loadproperties and an
expandproperties filter
<loadproperties srcfile="build.properties" prefix="test" prefixValues="true">
<filterchain>
<expandproperties/>
</filterchain>
</loadproperties>
does what you want.

Assuming that is not a bug, how can i solve the following issue.
I use in my build-files something of the kind like in the attached files. This
work as expected with ant version 1.8.4.
The output i get is:
test:
[echo] test.my.ldir = /home/lhersch
[echo] test.my.libf = /home/lhersch/somelib
With ant 1.9.4 i get the following output.
test:
[echo] test.my.ldir = /home/lhersch
[echo] test.my.libf = ${my.ldir}/somelib
Then i changed in my build.xml the value of prefixValues to true, because if
found the following in the description of the property-task.
"If you want to expand properties defined inside the same file and you use the
prefix attribute of the task, you must use the same prefix when expanding the
properties or set prefixValues to true."
After that the output with both versions of ant is:
test:
[echo] test.my.ldir = ${user.home}
[echo] test.my.libf = ${user.home}/somelib
Therefore i don't know, how should i change my build-files to work with ant
1.9.4.

I think this is not a bug but the behavior is correct.
When you set prefixvalues to true, Ant will add the prefix you've specified
when expanding ${} on the right hand side. This applies to all properties,
system properties included.
