When you run "ant clean test release", the reserved jars are part of the classpath (for example target test ) and would be locked by the windows process to protected itself. So you can not delete these file until the process exist and the file locks release.
I think "ant clean test release" would be in one process to run three target. For "ant clean,;ant test;ant release" there are three process to be executed one by one. When target release executes, the process of test has finished, of cause you can run target release to remove the jars. 2010-04-16 Sky Ao 发件人： Imner, Andreas 发送时间： 2010-04-16 17:26:27 收件人： [email protected] 抄送： 主题： Why is Ivy locking my resolved dependencies until Ant finishesprocessing? 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
