This isn't as bad as the delete task.
If you specify dir and file, it will delete everything in dir, not just
file.

If you have a <zipfileset> element with both a dir and a file attribute, it
will produce different results depending on the order in which those attributes
appear. If the file attribute appears first, it behaves as you would expect. For
example, with this:
<zipfileset file="file1.txt" dir="dir1"/>
It looks for a file named "file1.txt" inside the directory "dir1". However,
with this:
<zipfileset dir="dir1" file="file1.txt"/>
It looks for file1.txt inside the current working directory. This can be
verified by running the demonstration target I provide below with the -debug
switch, and reading the debug output.
I want to make clear that I'm aware that the docs for fileset say:
"Either dir or file must be specified" and that I might be doing it wrong. You
could argue otherwise, but perhaps that does in fact unambiguously imply that having both
is incorrect and hence the behavior is undefined. Be that as it may, what I would like to
know is this:
Is this a known, and expected behavior? Is it documented anywhere?
Should I assume that the order of attributes is significant in other places
throughout my build.xml file?
Here's a self-contained target that demonstrates this behavior:
<target name="oa">
<property name="JARCMD" value="jar"/>
<!-- Delete both zip files if they exist. -->
<property name="ZIP1" value="zip1.zip"/>
<property name="ZIP2" value="zip2.zip"/>
<delete file="${ZIP1}"/>
<delete file="${ZIP2}"/>
<property name="DIR1" value="dir1"/>
<mkdir dir="${DIR1}"/>
<!-- make sure there are no files named file1.txt or file2.txt in the
current directory, so we know they're not being read from there. -->
<fail
message="A file named file1.txt exists in the current directory.">
<condition><available file="file1.txt"/></condition>
</fail>
<fail
message="A file named file2.txt exists in the current directory.">
<condition><available file="file2.txt"/></condition>
</fail>
<touch file="${DIR1}/file1.txt"/>
<touch file="${DIR1}/file2.txt"/>
<zip destfile="${ZIP1}">
<zipfileset file="file1.txt" dir="${DIR1}"/>
<zipfileset file="file2.txt" dir="${DIR1}"/>
</zip>
<zip destfile="${ZIP2}">
<zipfileset file="file1.txt" dir="${DIR1}"/>
<!-- This file will not be included, because the dir attribute
comes before the file attribute. -->
<zipfileset dir="${DIR1}" file="file2.txt"/>
</zip>
<echo>Contents of ${ZIP1}:</echo>
<exec dir="." executable="${JARCMD}">
<arg value="-tvf"/>
<arg value="${ZIP1}"/>
</exec>
<echo>Contents of ${ZIP2}:</echo>
<exec dir="." executable="${JARCMD}">
<arg value="-tvf"/>
<arg value="${ZIP2}"/>
</exec>
</target>
