I'm in the process of extending the 'jar' task (for a bytecode instrumentation
tool). I want to
modify classes as they are added to a the jar. I definitely want to be able to
use the
'zipfileset' type. It appears as though the following operation works with
Jakarta Ant 1.5, but
does not work with Apache Ant 1.5.2. When I do this under 1.5.2, the
destination jar file gets
created, and appears to be the correct size, but I am unable to extract any of
the content except
for the manifest (with winzip).
If I run and with verbose mode, I can see that the first time I run this task,
it thinks it is
adding the files.
...
[jar] adding entry org/jboss/system/server/ServerImpl$ShutdownHook.class
[jar] adding entry org/jboss/system/server/ServerImpl.class
[jar] adding entry org/jboss/system/server/ServerImplMBean.class
...
The second time I run it, the task seems to know the archived file exists in
the zip.
...
[jar] org/jboss/system/server/ServerImpl$ShutdownHook.class omitted as
org/jboss/system/server/ServerImpl$ShutdownHook.class is up to date.
[jar] org/jboss/system/server/ServerImpl.class omitted as
org/jboss/system/server/ServerImpl.class is up to date.
[jar] org/jboss/system/server/ServerImplMBean.class omitted as
org/jboss/system/server/ServerImplMBean.class is up to date.
...
So, from Ant's point of view, everything succeeded. In fact, the unjar task
works w/o problem on
the new jar file. The problem is with loading classes from the jar, and
opening it in Winzip.
<jar destfile="D:\jboss-3.0.6\lib\jboss-system.jar">
<zipfileset src="D:\jboss-3.0.6\orig-lib\jboss-system.jar"/>
</jar>
Is this behavior to be expected/understood?
Thanks,
Jeff
