RE: pushd and popd

[Joe Cheng]

Don't know if this will help you, but are you aware that you can use "&" to
string together commands onto one line... this is at least true on Windows
2000, not sure about NT.

>From the command reference:

The ampersand (&) separates multiple commands on one command line. 
The parentheses groups multiple commands. 
The semicolon or comma (; ,) separate command parameters. 
The caret (^) cancels a subsequent command symbol's special meaning so you
can use a command symbol as text. 
The double ampersand (&&) causes the command following this symbol to run
only if the command preceding the symbol is successful. 
The double pipe (||) causes the command following this symbol to run only if
the command preceding the symbol fails. 

In other words, "pushd \\server\testdir\ & cd & popd" should work...

RE: pushd and popd

[Anthony Rodriguez]

OK.  I have resolved that Ant will not do this properly.  However, this can
be done in a batch file.  So now the question I have is, how do I get a
newline with the  task?

  



  

However the batch file (test.bat) looks like:
pushd \\server\testdir\cdpopd


I want the file to have the commands on separate lines.  \n and  don't
work with echo.

Wouldn't "net use z: \\server\share" get you what you need? You could
use the exec task to map the drive & then use copy

Don't you need to hook the whole thing together in quotes (like you would

If you're just wanting to execute a command in a directory other than the
current one, you can specify that directory with 's "dir" attribute.

RE: pushd and popd

[Anthony Rodriguez]

Interesting, I tried "pushd \\nqa2\testdir && cd && popd" from the command
line and it worked.

However when I tried it with ant, it hangs.  Here is my build.xml snippet:

 

  
  

 

I get these results:

C:\antdir>ant -v init pushpop -buildfile build.xml -Dnth.server=nqa2

Ant version 1.4Beta2 compiled on August 20 2001
Buildfile: build.xml

parsing buildfile C:\antdir\build.xml with URI = file:C:/antdir/build.xml
Project base dir set to: C:\antdir
Property ${classpath} has not been set
Property ${home} has not been set
Build sequence for target `init' is [init]

init:
 [property] Loading C:\antdir\build.properties

Build sequence for target `pushpop' is [pushpop]

pushpop:

 [exec] Microsoft Windows 2000 [Version 5.00.2195]
 [exec] (C) Copyright 1985-2000 Microsoft Corp.

Then it just hangs here.  Is Ant waiting for the cmd exec to return
something that it's not returning?  Does this happen whenever you run
something using cmd?

RE: pushd and popd

[Anthony Rodriguez]

What I'm really trying to acheive here is to map a network path to a drive
letter, then copy files to that path.  The copy utility I'm using was
developed in-house and has trouble with UNC paths.  It has other features
however that are specific and necessary to my environment.  So the idea was
to pushd the UNC path, copy to the new drive that pushd assigns, then popd
when I'm done.
However by reading the various responses, it looks like Ant wouldn't leave
me in the drive that pushd would assign.  Is this correct?  Is there a way
for me to work around this aspect of Ant?   Would I be better served by
writing a .bat file and executing that from Ant?

RE: pushd and popd

[Conor MacNeill]

Anthony,

What exactly are you trying to achieve?

pushd and popd are builtins to the Windows shell. This is why Ant cannot
execute them directly. The normal way around this would be to actually exec
cmd.exe and ask it to run the built-in.

In your case, however, the pushd and popd commands would only affect the
process that is created for the  operation. Any effect they did have
would be lost when the  completes and would not affect the Ant
process.

Perhaps you can explain why you need to pushd/popd at all and we could
suggest an alternative approach.

Conor

BINGO! That's why ant's implementation of  is so twisted. People at Sun
are looking into fixing the JVM for java.lang.Runtime.exec() by adding a way
to set the subprocesses working directory. The reason they don't allow
changing the cwd in a JVM is because of thread safety issues.

I had no trouble with this using ant 1.4. Perhaps it is a JVM problem.

Re: pushd and popd

[Frank E. Weiss]

I think this analysis is incorrect. Ant 1.4.1 asks the JVM to execute 'cmd /c
cd x && y', where x is the current working directory (user.dir) and y is the
command line (pushd \\nqa2\testdir\). Wouldn't the example give here result in
'cmd /c cd x && cmd /c pushd \\nqa2\testdir\'?

Part of the confusion is that the way ant works. The executable attribute of
the exec element is a misnomer. On Windows 2000 it just becomes part of the
string that the cmd shell is being asked to execute. At least that's my
interpretation of the Windows 2000 CMD ducumentation.

Re: pushd and popd

[vlad]

Even after you succeed running these [by using something like "cmd /c 
pushd ..." etc] it will be of no use: the commands take effect in the 
spawned processes and do not affect the current JVM process that is 
running ANT.

Unfortunately, Java does not support the notion of a changeable current 
process directory.

If you need pushd/popd only to change into another dir and do a quick 
command or two from there, the "cmd /c pusd ... && " syntax 
may do the trick.

Most likely they're built-ins rather than executables, so you'd need to
exec DOS's command shell, with pushd/popd as args to it.

I am not convinced this will have much effect. the first pushd is in one
instance of the shell, the popd is in a second instance .

It is like having two windows open, typing pushd in one and then going popd
in the other;

ok, that seemed to work.  But now it just hangs at pushd.  I can't seem to
run any tasks after that.
