I use Ant as the workhorse of a web application used across our enterprise for
all manner of software construction tasks for ~100 applications. I have a class
(AntTask) which gets instantiated for each request (build, deployment, test,
etc.). The class creates an org.apache.ant.Project, sets it's properties and
then sets the appropriate ${ant.file} which is found via the classpath using:
ClassLoader cl = this.getClass().getClassLoader();
URL url = cl.getResource("myAntFile"));
project.setUserProperty("ant.file", url.toExternalForm());
ProjectHelper2 ph2 = new ProjectHelper2();
ph2.parse(project, url);
I also create a temporary work area and set that as the "basedir" of the
Project before running "project.execute()".
Everything works fine unless my ${ant.file} uses the <antcall> task. Even
though the called target is in the same ant.file, I get an error:
"java.io.FileNotFoundException:
C:\FactoryFloor\widgets\MyApp\IterativeBuild\jar:file:\C:\SDF_Factory\lib\sdfant.jar!\config\int\SDFAntCommon.xml"
c:\FactoryFloor\widgets\MyApp\IterativeBuild is the directory that was set as
the project's ${basedir}. In looking at the source files for <antcall>
(CallTarget.java) and Ant (Ant.java), things are basically working correctly.
Ant.java assumes the build file is resident on the file system either in, or
relative to, the project ${basedir}.
Am I missing something? Is there a way around this aside from reading the
${ant.file} at startup and then writing it to a location on the file system?
That's not a huge deal to do, but I'd rather keep everything in the *.war.
Thanks,
Kevin
