Need method to get absolute path of Jar in <classpath> definition.
Summary: Need method to get absolute path of Jar in <classpath>
definition.
Product: Ant
Version: 1.5.3
Platform: All
OS/Version: Other
Status: NEW
Severity: Critical
Priority: Other
Component: Core
AssignedTo: dev@ant.apache.org
ReportedBy: cp1965@ROGERS.com
I looked at the Java code for Path and PathElement classes. These two classes
are used in ANT scripts to implement path blocks such as:
<classpath>
<pathelement path="lib1,lib2" />
<pathelement localion="lib/mylib.jar">
</classpath>
I am writing an ANT task that scans previously defined Jars (as above) and
calls the JUnit tests on them. The point is that I want to use a previously
defined Jar inside of <classpath>. The obvious way is to use id references
since ANT is XML. I can do that by putting id attribute and rely on XML to do
the rest.
<classpath>
<pathelement path="lib1,lib2" />
<pathelement id="ref.mylib" localion="lib/mylib.jar">
</classpath>
However once the <pathelement> (i.e. the object of type Path.PathElement), how
can I get the absolute file path to the Jar file? Intuitively, there should be
a pointer back to the containing Path object. I don't see it! Also, there
should be some sort of search method on the Path object to look for the
absolute path to the Jar file. We can assume that the Jar file exists because
the <classpath> has already run int the 'init' target.
You might say that the <classpath> block is only declarative and that the Java,
JavaDoc or similar programs will determine if the Jar file exists. I will
point out that there is a real necessity for a search method to look whether
the Jar file exists or not.
Furthermore, I suspect that this code already exists in your class loader. I
will seach for it. Such search method should be in the Path class.
