Hi everyone,
I have some java code that references file paths from a .properties file. I'm
currently using ant to do some token replacement based on absolute paths, and it is
causing some troubles when running from NT.
For instance, I have a foo.property file:
some.exec.path=@SOME_TOKEN@
and java code:
String execPath = System.getProperties().getProperty("some.exec.path");
System.out.println("I am about to Runtime.exec(" + execPath + ")");
and my ant script:
<property name="my.bin.dir" value="${basedir}/deploy/bin"/>
<replace file="foo.property">
<replacefilter token="@SOME_TOKEN@" value="${my.bin.dir}/foo.exe"/>
</replace>
When executed from a basedir of D:\foo\bar\frog (set by ant), my program outputs:
"I am about to Runtime.exec(D:foobarfrog/deploy/bin/foo.exe)" (broken)
If my foo.properties has
some.exec.path=D:\\foo\\bar\\frog\\deploy\\bin\\foo.exe
"I am about to Runtime.exec(D:\foo\bar\frog\deploy\bin\foo.exe)" (success)
I saw the <pathconvert> task, but it was not clear to me that one could pathconvert
ant properties (even though a property specifies a path).
This brings up another point: I would like to use ant to do "cross platform
deployment" by using an NT machine to do builds (and path configuration) for UNIX
boxes. If I were to do an "% ant release -Dosname=AIX" on an NT machine, all the File
instances created by ant should come out as /
Is it possible to tell ant to "use UNIX paths" instead of the system default?
I am currently considering a custom ant task to munge all the Project properties- if
run as a dependency of all other tasks, it could convert all the \ to / in the ant
properties. Java File objects seem ok with / as a file separator even on Windows
machines, so I think this will be ok.
Cheers,
josh
