Why is Ivy locking my resolved dependencies until Ant finishes
processing?
Hi
I have a problem with Ivy that is blocking me from using it for creating my daily builds. I am using Windows and this problem does not appear on, for example, MacOS.
My daily build -Ant target triggers (among others), the following Ant targets
1. clean - cleaning /build and /lib
2. test - resolving 3:rd party dependencies (conf="test") using Ivy to /lib, compiling classes + test classes and executing the junit tests
3. release - cleaning /build and /lib, resolving 3:rd party dependencies (conf="run") using Ivy, compiling the classes and assembling my webapp.
When running these targets within the same Ant "session" (like "/> ant clean test release") or when calling these targets from a single target, using the "ant" -task the following happens in the beginning of the "release" -target:
C:\dev\trunk\04_Implementation\webshop-ng\build.xml:228: Unable to delete file C:\dev\trunk\04_Implementation\webshop-ng\lib\activation-1.1.1.jar
But if I run the targets one by one, like
ant clean
ant test
ant release
... the problems does not appear
If I add a <sleep minutes="5"/> to my build.xml and the use handle.exe, a sysinternals program for checking file handles, I can see that the Ant java process has file handles open for all the resolved 3rd party jars in /lib
Also as a test, during the <sleep.../>, I tried deleting the files in /lib using Windows explorer, but of course this didn't work either.
Does anyone have a solution or suggestion for this issue? I don't think Im the only one using windows and multiple targets withing the same Ant "session"?
Regards,
Andreas Imner

Posted by "Imner, Andreas" <An...@kgk.se>.
I did some more testing regarding this and found out the real cause of the problem and the problem was me/Ant, not Ivy :-)
Earlier, I created the classpath for my <junit...> -task from 3rd party dependencies that was residing in an external directory and I only "cleaned" the /build directory.
When I started using Ivy, I used ivy:resolve tol "download" the .jars to lib and then I executed the <junit..> task, setting the classpath to all jars in /lib.
In a later step I would then "clean" the /build and /lib and for some reason it seems that my <junit ..> task (with fork="yes") would not let go of the files in the /lib folder unit the Ant process finished...
I will now try to use Ivys <cachepath..> task instead

I don't know, maybe you didn't had this problem before because you were using subant to call these targets? As far as I know, Ivy isn't locking any jars. If it does, it is a bug that should get fixed.
Btw, did forking the junit/javac tasks solve the problem?

But before I started using Ivy for resolving the dependencies there
were no file locking (see my reply that I wrote a short while ago).

My guess is that the VM is locking the jars in your lib directory after step 2 (compilation or executing the junit tests).
Did you fork the javac and junit tasks?
