RE: [platform-ant-dev] org.apache.ant's dependencies?

["Sikha, Naresh" <Naresh.Sikha@xxxxxxxxxx>]

Darin,

 

We're just making sure that the set of custom ant tasks we provide and public tasks available in ant have their dependencies satisfied. We're not particularly concerned about how our customers setup their ant class path because our tasks are always available via the antTask extension in org.eclipse.ant.core.

 

Now the only problem area left is if our ant tasks and/or buildfiles invoke an ant task in ant.jar/optional.jar. Namely the style task (we use XSL to generate more scripts). The style task is dependent on a valid transformer. It is also important to note that the style task is in ant.jar not in optional.jar. The JUnit task is in the optional.jar yet the Eclipse platform delivers JUnit (org.junit plugin).

 

Here is the strategy I've just formulated to get around this issue.

 

- Deploy a plugin (prefix with my namespace to not conflict with apache or ibm or eclipse versions) of xalan

- Deploy a plugin with an ant task that can update ant preferences

- In any ant buildfile that we provide/generate, make the first task to execute the one that can maintain ant preferences to have xalan in the classpath

 

Allow me to propose a strategy for eclipse going forward.

 

- Maintain 2 plugins - one for ant (org.apache.ant) and one for ant optional (org.apache.ant.optional).

- Maintain as part of the eclipse platform, plugins that will successfully resolve all dependencies of the org.apache.ant plugin. Some examples are:

    - javax.xml.parsers.*  -> org.apache.xerces

    - javax.xml.transform.* -> org.apache.xalan

 

Thanks for your help!

You 
could do this by programmatically modifying the preferences: 
        call 
AntCorePreferences.setCustomURLs(URL[] urls) where urls is the collection of 
pre-exising URLs (maybe none) plus the URLs for the JARs you wish to add to 
        the Ant runtime classpath. 

I curious on how you are going to get closure on the set 
of JARs that your users will require...or is it just a best guess?

Can you explain in more detail, or point 
to documentation? 
  
Any solution that can obviate our 
customers' having to modify preferences is the favorable approach. 
  
Running vanilla Ant on Unix (or a Windows network drive) 
allows a system administrator to provide dependent jars into the globally shared 
${ant.home}/lib directory. :) 
  
Thanks.

You will need to set the runtime classpath for 
Ant. 
You can do this both programmatically or from the Ant Runtime 
preferences (globally) or on a particular Ant launch configuration. 

There 
are not plugins in Eclipse for all of the dependencies to satisfy the tasks in 
org.apache.ant. 
It is up to the user (as it is from the Ant 
commandline) to set up the Ant runtime classpath to satisfy the dependencies for 
the tasks the user wishes to execute.

Hello Ant Core. 
 
How 
can I execute tasks in Ant such as <style/> within Eclipse? Here's my 
problem. It seems that any plugin that has a  task defined that has 
classpath dependencies needs to express dependencies on the appropriate plugin 
that has those classes. 
 
Specifically <style/> needs 
xalan, correct? But the org.apache.ant plugin doesn't have a dependency upon a 
xalan project. 
 
Your help in this matter is greatly 
appreciated. 
 
Thanks.
