It seems that something has changed between Ant 1.6.2 and 1.7.0 in the
way the ant.version property is handled when another build file is
invoked using the <ant> task.
Given the following files:
main-build.xml:
<project name="test-case-main-build" default="main-build">
<target name="main-build">
<echo>Ant version is ${ant.version}</echo>
<ant antfile="sub-build.xml" inheritAll="false"/>
</target>
</project>
sub-build.xml:
<project name="test-case-sub-build" default="sub-build">
<target name="sub-build">
<echo>Ant version is ${ant.version}</echo>
</target>
</project>
I get the following results:
Ant 1.6.2:
C:\...>ant -f main-build.xml
Buildfile: main-build.xml
main-build:
[echo] Ant version is Apache Ant version 1.6.2 compiled on July 16
2004
sub-build:
[echo] Ant version is Apache Ant version 1.6.2 compiled on July 16
2004
But with Ant 1.7.0:
C:\...>ant -f main-build.xml
Buildfile: main-build.xml
main-build:
[echo] Ant version is Apache Ant version 1.7.0 compiled on December
13 2006
sub-build:
[echo] Ant version is ${ant.version}
Is this an Ant bug? It seems reasonable that ant.version should not be
inherited, but I would have expected the new Ant "environment" to detect
its own version and set the property (and maybe other ant.* properties
too), and clearly it did that before.
Thanks,
