I'm performing the Copy task on a directory structure. I have to take care
not to include binary files whenever I do filtering of tokens because there
may be @'s in binary files, especially .gif files, which would cause those
files to be corrupted.
In order to achieve this, I perform the copy in two passes. In the first
pass, I copy and filter all the text-based files that have tokens in them,
explicitly skipping the files I've designated as "binary". Then in the
second pass, I do a normal copy, this time getting all the binary files that
weren't copied in the first pass. Here's the excerpt from by build.xml:
<target name="copy" depends="init">
<echo message="Using environment variables
from ${env_file}"/>
<filter filtersfile="${env_file}"/>
<!-- copy and parse the non-binary files -->
<copy todir="${builddir}" verbose="true"
filtering="true">
<fileset dir="./checkout/rmc"
defaultexcludes="yes" casesensitive="false">
<exclude name="**/*.java"/>
<exclude name="**/*.jar"/>
<exclude name="**/*.zip"/>
<exclude name="**/*.gif"/>
<exclude name="**/*.jpeg"/>
<exclude name="**/*.jpg"/>
<exclude name="**/*.doc"/>
<exclude name="**/*.pdf"/>
<exclude name="**/*.exe"/>
</fileset>
</copy>
<!-- copy files that weren't copied in the
previous step -->
<copy todir="${builddir}" verbose="true"
filtering="false">
<fileset dir="./checkout/rmc"
defaultexcludes="yes" casesensitive="false">
<include name="**/*.java"/>
<include name="**/*.jar"/>
<include name="**/*.zip"/>
<include name="**/*.gif"/>
<include name="**/*.jpeg"/>
<include name="**/*.jpg"/>
<include name="**/*.doc"/>
<include name="**/*.pdf"/>
<include name="**/*.exe"/>
</fileset>
</copy>
</target>
Is there a more efficient way to do this? Is there a way to
"detect" a text-based versus binary file with ANT? I've considered having
an external file containing patternsets that the build.xml would reference .
That way, if a new binary type showed up in the directory structure (say, an
.xls ), then only this file would have to be modified, not the build.xml.
Thanks
