How to add Ant properties to the AntBuildFile?

Hi Ilya,
Such properties are not supposed to be added programmatically so there is no dedicated open API to do this.
However, you may try add them in a the way the "AntExplorer" class manages them:

First, ensure your file is added to the AntConfiguration:
AntBuildFile buildFile = AntConfiguration.getInstance(project).addBuildFile(file);

Then you may add properties:

    final AbstractProperty.AbstractPropertyContainer options = ((AntBuildFileBase)buildFile).getAllOptions();
    final ArrayList<BuildFileProperty> properties = AntBuildFileImpl.ANT_PROPERTIES.getModifiableList(options);
    properties.add(new BuildFileProperty("aaa", "aaaValue"));
    properties.add(new BuildFileProperty("bbb", "bbbValue"));
    AntConfiguration.getInstance(myProject).updateBuildFile(buildFile);

I work with IDEA 8.1.3.
I've tried the suggested code and here is what I got:

Similar exception happens with cast to AntBuildFileBase interface.
Seems strange for me - is it classloaders issue?

Yep, classloaders are the reason. Please check that the classpath of your plugin does not contain any libraries from Ant plugin. Instead your plugin should depend on Ant plugin

Thanks a lot Eugene. Everything works fine.

I use the following trick:

- to compile my plugin I have to add AntSupport jar to plugin module dependencies
- but to debug my plugin I have to remove AntSupport jar from the module dependencies

Also I've added <depends>AntSupport</depends> to my pluging.xml.

You are welcome ;-)
Doesn't DevKit plugin do the job for you?

Hello Ilya,

Thanks a lot Eugene. Everything works fine.

I use the following trick:

- to compile my plugin I have to add AntSupport jar to plugin module
dependencies - but to debug my plugin I have to remove AntSupport jar
from the module dependencies

It's easier to add AntSupport.jar to the classpath of the IDEA SDK - then
you can keep it there and it won't cause classloading issues.

Brilliant, Dmitry! Exactly what is needed.

Thanks for the support guys.

I have also added the AntSupport jar into the SDK classpath but that doesn't work for me.
I try to execute some Ant script in the scope of a ClassPostProcessingCompiler and I get also a cast exepction
