Re: Property vs. user property - what's the difference?
Thanks a lot for this very useful and clear information. I am surprised to read that can override properties. Is there a reason for it? Patrick M.

Classpath problem
Hi all, I’m having a very odd problem concerning the used classpath in ant targets. I have target1 and target2 like this: Basically, target1 is running a set of JUnit and Mock tests, and target2 is starting WebLogic. If I try to run both targets separately everything goes fine. The problem is if I create a third target that runs both target1 and target2 in sequence. Target1 runs fine and then target2 fails with an exception related with Mock objects. Therefore, it seems that the classpath that I define for target1 is available to target2 as well. I would expect that the classpath that I define is just local to the target I’m running. Is this assumption correct? Is there any way that I can run both targets in sequence, without “inheriting” the classpath from target1 at target2 level? Thanks!

The suggestion to run ant with the verbose switch (-v) was to get *you* to
look at what *your* build is doing on *your* system. Based on your earlier
comments it appears to me that something has changed on your system which is
resulting in the unexpected failure of the build and basically you'll need
to figure out what that problem is. Rather than trying to debug a build as
is - I suggest you focus on the immediate issue of resolving the problem you
have with the junit task execution. You can do this reasonably easily by
creating a simple testcase and a minimal build file.
For example:
1. create a new directory somewhere
2. create the following java source file in that directory
// DemoTestCase.java
import junit.framework.TestCase;
public class DemoTestCase extends TestCase
{
public void testSomething() throws Exception
{
System.out.println( "Hello" );
}
}
3. create a build file that will execute this testcase
4. run the build
$ ant
5. check the output (should be something like the following)
| Buildfile: build.xml
|
| build:
| [javac] Compiling 1 source file to C:\dev\test\sample
|
| test:
| [junit] Running DemoTestCase
| [junit] Hello
| [junit] Tests run: 1, Failures: 0, Errors: 0, Time elapsed: 0.015
sec
|
| BUILD SUCCESSFUL
| Total time: 2 seconds
6. if the build does not complete successfully then run ant again with the
verbose option and try and figure out the reason (which should be clear
given the simplicity of the project definition)
7. if the build is ok then compare what is happening in the sample build
with
your project (possibly by modifying the test project to use similar
path definitions, test task parameterization, and so forth).
Good luck!
Cheers, Steve.

Re: Ant task equivalent to the "ln" unix command
There is the task, which only works on Unix systems (IIRC it works to a slight degree on Cygwin but I wouldn't recommend it). calls the ln executable, but be sure to read the manual and experiment thoroughly if you choose to use this task as its behavior is a little special and seems to give users fits at times.

RE: test for directory existence
IMHO. I don't think it is a matter of whether the second mkdir "completed" or not here. As Jan said, mkdir has the responsibility to make sure the directory exists when it ends. In the case of the first mkdir, the directory had to be created so mkdir said it did it. In the case of the second mkdir, the directory was already there so mkdir had nothing to do so it said nothing. In both cases mkdir "completed" its responsibility successfully. This is essentially what I would expect to see. It would probably be better if the -d output said that the directory was already there and the create was skipped but I would not want that much info in the standard message.

Re: Ant task equivalent to the "ln" unix command
If I were going to do this (and I probably wouldn't), I would DL www.sysinternals.com's JUNCTION utility and conditionally create a macro to call or based on the OS.

Re: Property vs. user property - what's the difference?
I once researched this... I think what happened was just that the author of used the wrong method call. I can say this without sounding too terrible because I did it once myself in Ant's code, except that my mistake was discovered soon enough to avoid compromising the API. Regarding , backward compatibility being taken as seriously as it is in Ant, the decision was made to let the error stand rather than break builds in the wild which depended on this behavior.

Real meaning of javac target/source attributes
It was my understanding that the target/source attributes in the javac task forced the compiled classes to be compatible with old versions. What I also assumed was that it wouldn't let me compile something if I was using an API that was newer than the 'target' attribute. For example, my task compiles code that contains the java.lang.Boolean.parseBoolean(String s) method just fine -- even though that method was introduced in Java 1.5 and I have my target and source set to 1.2. Is there any task or utility out there that will actually check to see if I am using an incompatible API -- without me having to download and install really old JDKs and compile with them? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Real meaning of javac target/source attributes
Your assumptions are incorrect; @target & @source have to do with language features and class file formats, not APIs. The only 100% safe way I know of to make sure you aren't using improper APIs is to make sure you are compiling against the class library from the *lowest common denominator* JDK version you need to support. There are other ways to accomplish this (and Ant itself makes use of some of those techniques) but you can't rely on those being 100% safe. -- Jeffrey E.

Calling one build file with another - please respond
My goal is do a checkout of each project and then do a build. For my first project when I run individually,I call ant so it works but for my 2nd project ...I had to ant -lib .\lib . it works too. How to pass this information to the 2nd build...using the ant task. The below mentioned doesn't work..suggestions...How to pass options .. If you have specifics , you need to clarify please do so.

Re: Troubles with Ant's configuration
The word "sometimes" hints on a third party software that breaks the system. There are few candidates to look for - antiviruses and software firewalls. I have seen them affecting Java application (and only them!) in very strange ways. Personally I always disable them and for a long time I have had viruses only with newly reinstalled computers (even though they came with antiviruses installed), but you will need a broadband router to protect your computer at home. Or maybe it is an opposite - a worm intercepting system events affects ANT on your computer. Please check that other running applications do not deplete system resources - for example, memory and windows handles. Also hardware failures (memory, overheating, not enough power, etc.) can result in an unexplainable behaviour. Finally, your disk directory structure can be broken and you may need to run disk doctor to fix it. - Alexey. KoloSSo wrote: Hi!!!

RE: AW: Broken Junit targets
Hi again, Somehow my build is running tests again. I don't know what I did. I was asking questions on ##java, and a flame war started and then somehow everything worked. There is no moral or antidote, but I just wanted to thank you for your help. Peter, Jan, and especially Steve, thank you for reading my e-mails and especially for taking the time to respond. MY girlfriend knows about ant. She enjoys typing ant at the prompt and imagining tiny ants swarming around inside the computer. I try to tell her it's just one ant, but that it moves so fast it looks like a whole bunch of ants. But I guess I don't know what's really going on either. I just use the tools. So I guess I'll be back next year when my build breaks in some mysterious way. Iĺl be back. Until next time, keep up the good work. YOu guys do are doing a great thing.

Problems when initiating Ant
Hello again!!! When I tried to initiate Ant, he does not recognize the build.xml file who is located in %ANT_HOME%\bin directory. Instead, I receive the following output when i tried to initiate Ant: C:\ant\bin>ant Usage: java [-options] class [args...] (to execute a class) or java [-options] -jar jarfile [args...] (to execute a jar file) where options include: -client to select the "client" VM -server to select the "server" VM -hotspot is a synonym for the "client" VM [deprecated] The default VM is client. -cp . . . -esa | -enablesystemassertions enable system assertions -dsa | -disablesystemassertions disable system assertions The same output is launched every time I want to execute: C:\ant\bin>ant -diagnostics C:\ant\bin>ant -version .. I'm using Windows XP Professional Version 2002, Ant 1.6.5 (binary version), jdk1.4.2. I formed the Environment Variables of the following form: ANT_HOME=c:\ant\ JAVA_HOME=C:\Program Files\JBuilderX\jdk1.4\ PATH=C:\Program Files\JBuilderX\jdk1.4\bin\ ; C:\ant\bin\ Do I miss something?? Thanks, Deyner
Re: Property vs. user property - what's the difference?
On Thu, 16 Feb 2006, Patrick Martin <[EMAIL PROTECTED]> wrote: > I am surprised to read that can override properties. Is > there a reason for it? Matt got it almost right. Up to Ant 1.3 (I think) the check whether a property existed was inside of the task and not inside the setProperty method. This left task writers who wanted to keep properties immutable with implementing this check themselves ( for example). Then setProperty was "fixed" and we broke . I don't recall whether we broke any Gump[1] builds. In any case at that point had been known as a workaround if you really wanted to modify properties. This had been mentioned on the user list multiple times so we knew we'd break a lot of build files with the next release. setNewProperty was introduced and available used that.

This is what happens in Ant as well. During development from time to
time a committer will build and test Ant against a JDK 1.2. And doing
so is part of the release process.
Actually it is even worse than that, you have to compile the binary
you publish using the lowest common denominator JDK, otherwise you may
end up with binaries that don't work on the "lower" VM even though the
source would compile fine.
Say we have class A with a method public void doSomething(Object o)
in version 1.2 and you invoke this in your code via doSomething("").
In version 1.3 an overload doSomething(String s) gets introduced.
If you compile on JDK 1.2 everything is fine and if you do so on JDK
1.3 it is as well. But by compiling it on JDK 1.3 your class will be
looking for the String signature at runtime and your code will fail
with a NoSuchMethodError in a 1.2 VM.
There are several examples of this in the Java class library.

Such as? I'm really curious.
