OT: Run Ant in MingW shell?

OT: Run Ant in MingW shell?

[Kai Grossjohann]

I searched Google and Gmane for a pertinent group but couldn't find
one, so I thought maybe I'll be lucky here ;-)
Please don't hesitate to point me to the right group.

I started a MingW shell under Emacs via the following setup and then
hitting M-x shell:

(setq explicit-sh.exe-args '("--noediting" "--login" "-i"))
(setq explicit-shell-file-name "sh.exe")

In that shell, I say "cd work/bla", then I say "ant -emacs compile",
and this is the response:

~/work/bla> ant -emacs compile
java.lang.NoClassDefFoundError: org/apache/tools/ant/Main
Exception in thread "main" ~/work/bla> 

I look at $CLASSPATH and it's the same as under CMD.EXE.  But there,
Ant works.

Any idea how to get it working?

tia,
Kai

There's a MinGW mailing list (sorry, I don't know its exact name)
which I think is a better place.

No idea, but here are a few questions that might provide some insight:

  . What happens if you start the MinGW shell outside Emacs with the
    same options shown above, and then run Ant?

  . What happens if you start CMD under Emacs and then run Ant?

  . What happens if you start the MinGW shell outside Emacs, but with
    stdin and stdout redirected to a file, and then run Ant (e.g.,
    have the Ant command on the file where you redirect the shell's
    stdin)?

Okay, I'll have a look.  (In fact, I found
gmane.comp.gnu.mingw.{user,msys} on gmane.  I'll ask there.)

Correction: it seems that $CLASSPATH looks like c:/foo;c:/bar, note
the semicolon and the forward slashes.

Same as above.

Works fine.

No idea.

That shouldn't be a problem: I'm guessing that $CLASSPATH is
interpreted by Ant, not by CMD, so it's not necessarily a problem.
Semi-colon is what is used on Windows since a colon is a valid part of
an absolute file name.

Does $CLASSPATH look different under the MinGW shell?

The forward slashes come from some code in my .emacs file.  I forget
why I have this, but if that proves to be the problem, then I'll of
course change that code in .emacs (or remove it, or whatever).

Silly me.  Typing "ant" will run the Bourne shell script.  I need to
say "ant.bat" to run the Windows thing.

Alas, typing "ant.bat -emacs compile" in the MinGW shell leads to the
shell trying to interpret ant.bat as a shell script.  That won't work,
of course.

~/work/evITA-Web> ant.bat -emacs compile
/c/Programme/Apache-Group/apache-ant-1.5.4/bin/ant.bat: @echo: command
not found
/c/Programme/Apache-Group/apache-ant-1.5.4/bin/ant.bat: line 3: syntax

~/work/evITA-Web> 

Hm.  Googling for "bat mingw shell"...  Ah!  Found an article on
Cygwin with the same problem.  Typing

cmd //c /c/Programme/Apache-Group/apache-ant-1.5.4/bin/ant.bat -emacs
compile

really works!

Now it would be nice if it could be made automatic.  I'll ask the
MinGW folks, I guess.

Automatic in what sense?  The shell cannot know that a file foo.bat
needs to be run thru "cmd /c", so it's your responsibility to type
that on the command line.

Why can't the shell know?  In a Windows environment, it seems useful
to just tell it so.

(Actually, there must be a registry of some kind in Windows that
says that *.bat files are associated with cmd, but I don't know the
details.)

Am I on the wrong track in some way?

That means someone should hack the Bash sources to add the code to do
this.  Originally, Bash simply looks at the executable bit returned by
`stat' and at the magic number.  If the magic number is "#!", it then
reads the first line of the script looking for the interpreter.
(Actually, I think this is in the kernel, at least on some flavors of
Unix.)

No, AFAIK the association of *.bat files in inside CMD itself, not in
the registry.

That is correct. The association for .bat files in the registry is
"%1" "%*", so the real association must be done inside CMD and
Explorer.

Hi Kai,

I just wanted to make sure that you are aware that the
JDEE provides comprensive support for running Ant scripts
from Emacs. You have a choice of either launching a 
vm directly from Emacs to run the Ant script or to
run the Ant from the BeanShell. In either case, there
is no need to use an intermediate shell and hence deal
with environment variable inheritance issues.

Yes, I set the build function to use Ant, and told <f9> <f9> to do
like C-c C-v C-b.  That's what you mean?

Very nifty.  Use it often.

However: I'm doing servlet developing, so I have an Ant target for
running Tomcat.  It never stops, so that I can look at the output.
So in the morning, I open a shell window (eshell currently), then
invoke "ant -emacs tomcat" from there, and from then on I can see all
debugging output in an Emacs window, for easy searching etc.

I do use <f9> <f9> routinely for compiling my *.java files and for
removing and restarting the servlet (using the Ant tasks provided for
this).

Hm.  Now that I think of it, if there is an easy way to tell C-c C-v
C-b to run a different target, then I could use it to run the
"tomcat" target, then rename the resulting compilation buffer.  This
would give me the same thing, but in two compilation buffers.

Hm.  Hmmm...  Why not?  Let me try (tomorrow).
