[HOW] Setting ANT_HOME properties in runtime [message #300871]

Hi,

I would like to change ANT_HOME property of Ant plugin from the code. Property changes, but JARs list is still the same (JARs from the old ANT_HOME are in list and they are used by Ant plugin). How can I force Ant plugin to reload/recalculate JARs list and use JARs from new ANT_HOME?

I try to change ANT_HOME using the following code:

AntCorePreferences antPreferences = AntCorePlugin.getPlugin().getPreferences();
antPreferences.setAntHome(...);
antPreferences.updatePluginPreferences ();

Thanks in advance!

See the code in AntRuntimePreferencePage.performOk, the AntClasspathPage and
the ClasspathModel
found in org.eclipse.ant.internal.ui.preferences of the org.eclipse.ant.ui
plugin.

Essentially you will need to call
antPreferences.setAntHomeClasspathEntries(IAntClasspathEntry )

ANT_HOME are in list and they are used by Ant plugin). How can I force Ant

The problem is that AntClasspathEntry (which implements IAntClasspathEntry) is marked as "internal". I would like to avoid relying on "internal" classes. And as far as I can see there is no other way to create AntClasspathEntry object.

AntRuntimePreferencePage, the AntClasspathPage and
the ClasspathModel also use a lot of "internal" structures and functions which are hard to be reused.

Possible solution could be antPreferences.setAntURLs. But it's deprecated. I would like to avoid using deprecated methods.

May be a better solution exists?

Any suggestions would be very appreciated!
Thanks in advance!

You are correct in that there is no programmatic way to set the Ant home
classpath entries without using internal or deprecated means.

The API for Ant core and Ant UI is very limited and there are no plans
currently to extend the API
