Summary: apply task strips needed quote character from command
line
Product: Ant
Version: 1.6.5
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: major
Priority: P2
Component: Core tasks
AssignedTo: dev@ant.apache.org
ReportedBy: bpracht@nc.rr.com
I'm trying to compile a C program with a fix level that must be passed in as a
string macro. I'd like to have the program do something like
cc -c -o program.o -DFIXLVL=\"testFixLevel\" program.c
such that the quote characters are placed in the C program. It reports that it
passes on the quote characters, but it really doesn't. Included below are test
files needed to run this scenario. Please run ant -debug to verify and observe
the -DFIXLVL on both Ant's output and the output from listargs.
Thanks,
Ben

That's interesting, but irritating. Btw, I modified my test case, and verified
that the quote disappears even when it's in the middle of an argument. Someone
did something bad somewhere.

So is the only solution to call cmd.exe /c then?

Hmm. Now how does that make sense? Hmm... the only way is that the problem is
in the Windows APIs (that I am guessing are) shared by CMD.EXE and the JVM's
process execution component. I don't have a Unix box anymore :( ... can anyone
run a test to see if quotes are preserved in arguments on a non-Windows platform?

My point being that perhaps a direct call to CMD goes through one less level of

Example showing that this is not Ant's fault
extract the files into a folder and run ant. You will see two sets of output,
one from calling "java ShowArgs" with <exec> and quotes embedded in XML args;
the other calling Run with <java>, which uses the core Java APIs to run java
ShowArgs with quotes specified in arguments. The quotes still disappear; thus
I must attribute this behavior to Java. I am running Sun JDK 1.4.2_10.

Thanks for your quick response.
Unfortunately, your example is missing the arguments for the <java
classname="Run" classpath="." />.
But, if I understand what you're saying, Ant is correctly converting " to
quote (") in the string, then calling making a core Java API call to run
java.exe with the specified arguments, including the quoted argument. Then, the
Java API, according to your example must be stripping out quotes in the middle
of the argument. Am I correct? If so, which core API call is it making, and
can I have an example of it?

I just tried cmd.exe from the command line, and it still stripped the quote
characters, so I can now blame Microsoft. My solution was to do something like
this "-DFIXLVL=\"Test\"", and that seems to work, at least for
Windows. While this is not an Ant bug, this kind of information would still be
useful in the Ant docs somewhere.
Thanks for your help, I've remarked the bug as invalid.

If so, how would I then make that call to cl.exe or whatever compiler, given
that it'll have those quote characters in them?
