Summary: Property expansion inaccurate for prefixed file-based
property loads.
Product: Ant
Version: 1.8.1
Platform: PC
OS/Version: Windows NT
Status: NEW
Severity: normal
Priority: P2
Component: Core tasks
AssignedTo: [email protected]
ReportedBy: [email protected]
Unexpected behaviour change between Ant 1.8.0 (OK) and Ant 1.8.1 (wrong).
<property file="foo.properties" prefix="prfx" />
Loading properties from a file should apply the prefix only to the newly loaded
properties. The prefix should not be used for property expansions on the value
side.
Below build.xml works with Ant 1.8.0 and fails with Ant 1.8.1:
---8<---
<?xml version="1.0" encoding="UTF-8"?>
<project name="Test1" default="test1">
<target name="test1">
<echo file="foo.properties" message="abc=$${def}" />
<property name="def" value="ghi" />
<property name="prfx.def" value="jkl" />
<property file="foo.properties" prefix="prfx" />
<echo message="Value of $${prfx.abc} is ${prfx.abc}, should be ghi,
should not be jkl." />
</target>
</project>
---8<---
1.8.0:
[echo] Value of ${prfx.abc} is ghi, should be ghi, should not be jkl.
1.8.1 (wrong):
[echo] Value of ${prfx.abc} is jkl, should be ghi, should not be jkl.
