"If Ant fails, it will return a non-zero exit code" - doesn't hold any
more ?
Hello,
It's being said on this list that "If Ant fails, it will return a non-zero exit
code". Unfortunately, it doesn't work for me:
1) I have a build.xml that fails (see below)
2) I call 'ant' from Perl script, using 'system()' call and expect to see
a non-zero exit code from ant.
3) What I see *is* zero.
Ant v1.5.4, j2se v1.4.2, Windows 2000
Here's the code:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ build.xml ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
<?xml version="1.0" ?>
<project name="Test" default="compile">
<target name="compile">
<fail message="AAAAAAAAA"/>
</target>
</project>
~~~~~~~~~~~~~~~~~~~~~~~~~~ show_exit_code.pl ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
use strict;
use warnings;
( @ARGV == 1 ) or die "Param: command to run";
my $command = $ARGV[ 0 ];
my $exit_code = ( system ( $command ) / 256 );
print "Exit code of running [$command] is [$exit_code]\n";
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Running it:
>perl -w show_exit_code.pl ant
Buildfile: build.xml
compile:
BUILD FAILED
file:E:/Projects/AntFailure/build.xml:5: AAAAAAAAA
Total time: 2 seconds
Exit code of running [ant] is [0]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Running script with something else that fails (to make sure it's not lying)
>perl -w show_exit_code.pl "java Opa"
Exception in thread "main" java.lang.NoClassDefFoundError: Opa
Exit code of running [java Opa] is [1]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
As you may see, the exit code of failing ant project is zero. Can somebody,
please, explain this to me ?

Sure, removing the clean-up code does have it's side effects but let it be if it
returns me the correct exit code now.

That would be the cleanest solution and I wouldn't mind using it. I bet ant.bat
developers wouldn't mind either :) Can anybody suggest how to do that (Windows
2000 if that matters) or it's a 100% dead end ?

err, well, yes - but you've also removed all hooks that clean up your
environment.
The real problem - AFAIU and I know virtually nothing about Windows
batch programming - is that you can't store the exit code of Java and
exit the batch file with that code at a later stage (at least not in a
way that works on Win9x).

That's strange, my previous message doesn't seem to appear on list, so I'll
repeat it here. I think I've found the problem, taking a look on ant.bat:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
:runAnt
"%_JAVACMD%" %ANT_OPTS% -classpath "%LOCALCLASSPATH%" "-Dant.home=%ANT_HOME%"
org.apache.tools.ant.Main %ANT_ARGS% %ANT_CMD_LINE_ARGS%
goto end
:runAntWithJikes
"%_JAVACMD%" %ANT_OPTS% -classpath "%LOCALCLASSPATH%" "-Dant.home=%ANT_HOME%"
"-Djikes.class.path=%JIKESPATH%" org.apache.tools.ant.Main %ANT_ARGS% %ANT_CMD_LINE_ARGS%
goto end
:end
set LOCALCLASSPATH=
set _JAVACMD=
set ANT_CMD_LINE_ARGS=
if "%OS%"=="Windows_NT" @endlocal
:mainEnd
if exist "%HOME%\antrc_post.bat" call "%HOME%\antrc_post.bat"
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So my thought is following: since running Java isn't the latest operation in
the batch file - all following operations simply overwrite the exit code of java
process which is indeed 1 when it fails. But since following operations do succeed -
what is finally returned to the outside world is *their* exit code, not java's
(never was a batch-files pro, so this is only a guess).
After I removed everything after first "%_JAVACMD%" in :runAnt label (to make sure
"%_JAVACMD%" is the latest operation executed) - the exit code I received from running
'ant' has become 1 for failed projects.

Whops, I didn't notice that one. Thank you !

I think it'll also work. But for our needs - we'll just make sure nothing is
launched from batch file after the Ant's java process.

I think it doesn't work for the Windows batch file.
As you are using Perl anyway, try runant.pl instead.

Try this
(from Perl)
my @xsl = ("java", "org.apache.tools.ant.Main.main");
system(@xsl);

I ended up with the following code (in fact, it was surprisingly simple to save
the java process exit code in variable and exit with it later on):
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
%JAVA_HOME%\jre\bin\java ... org.apache.tools.ant.Main
set exit_code=%ERRORLEVEL%
... // some more commands
exit /b %exit_code%
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If such a code was used in original ant.bat - it's exit code returned to the
outside world was indeed 1 for the failed projects.
P.S.
DOS manual to the rescue !

You can call cmd.exe and send along the command line parms of the batch file
(and get all of the env vars set properly)
OR you can call the perl script I mentioned earlier
Your choice

Martin
