DO NOT REPLY [Bug 46842] New: Support Classpath Wildcards
https://issues.apache.org/bugzilla/show_bug.cgi?id=46842
Summary: Support Classpath Wildcards
Product: Ant
Version: 1.7.1
Platform: All
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P2
Component: Core
AssignedTo: notifications@ant.apache.org
ReportedBy: mbm@ptc.com
Ant doesn't support Java 1.6's classpath wildcards (eg foo/*) for forked
<java>.
http://java.sun.com/javase/6/docs/technotes/tools/windows/classpath.html
It happens in the creation of the task's path, in Path.addExisting().
If I change the first line of code in this block:
http://svn.apache.org/viewvc/ant/core/trunk/src/main/org/apache/tools/ant/types/Path.java?view=markup
if (f.exists()){
setLocation(f);
} else {
log("dropping " + f + " from path as it doesn't exist",
Project.MSG_VERBOSE);
}
to this:
if (f.exists() || (f.getParentFile().exists() &&
"*".equals(f.getName()))) {
I get the behavior I desire. Maybe this change would create problems for other
usage scenarios, but it would seem unlikely. If so, maybe an attribute to
enable support for java classpath wildcards could be added.

That's excellent news! Thanks!

We discussed in this thread
http://ant.1045680.n5.nabble.com/Bug-fix-for-v1-8-1-in-the-near-future-td3244614.html
At that time the only blocker is an issue with special environment variables
whose name start with an equals sign.
I hope we can release 1.8.2 before the end of the year. Maybe even end of this
month.

the classpath-wildcard functionality is provided by using filesets and works
for all tasks and all versions of Java.
I'd be a bit reluctant to change the code since we'd get surprising results
when running on Java 1.4 or Java 5 where people expected foo/* to do something
because it works "on my machine".

Hi Stefan,
Our team has just run into this issue. We need to be able to run tests on
Windows and can no longer do so.
I see this defect is marked fixed for 1.8.2. Any ideas (even rough ones) as to
when 1.8.2 will be released?
Thanks!
Jason

(In reply to comment #1)
The reason I'm requesting support for the new Java classpath specification
feature is that we have situations where the classpath on the forked java
exceeds the cmd length allowed by the platform.
I need a solution other than telling users to use subst drives to shorten
paths. This work around will only work for so long.
If someone develops a script using Java 6 features and expects it to work on an
older version of Java, the verbose output should be sufficient for the (old
Java) user to quickly determine why it does not work as expected.

I ran into this issue when trying to get over a z/OS classpath limit. You
cannot have a classpath over 6129 characters. When the JUnit task forks a
process the paths are turned into fully qualified pathnames. So, with a lot
of jars, it is not too difficult to exceed 6129 characters. (Unfortunately,
the VM just truncates the classpath without warning).
The patch that Mike Murray supplied works.
