> Jira AVRO-146 enabled easy eclipse setup for Avro. But it had a few minor issues:
>    - It downloaded the ant-eclipse plug-in directly without using Ivy. This problem has been acknowledged in the JIRA itself. Thus if you clean up the project and rebuild, it'll go and fetch the plug-in again. That means one cannot do "ant clean" when offline.
>    - Eclipse project used the external jar files from ivy cache locations rather than from the place where they have been retrieved into. It's not a big issue, the only concern is that ant and eclipse will use two different sets of jars though with identical contents.
>    - Ant-eclipse plug-in was downloaded into build/lib, which will get included in ant builds, though the builds would never use it.
> The attached patch fixes all these issues. The ant-eclipse plug-in now gets retrieved by ivy into a separate directory build/lib/ant-eclipse. Unfortunately, the is patch adds a new file ivysettings-ant-eclipse.xml in the base directory. Alas, one cannot specify ivy settings inline in build.xml, you need an external settings file.
> There is still one more small problem. Eclipse projects traditionally use the built-in JUnit instead of external jars. The use of built-in JUnit within a project is specified by a classpathentry of kind "con" in the .classpath directory. The projects with JUnit will have two classpathentries of "con" kind - one for JRE and the other for JUnit. But Ant-eclipse does not support more than one classpathentry of "con" kind, which is already used by the JRE. Thus we cannot fix this problem until ant-eclipse removes this limitation.
> Eclipse users, please give this patch a try. Thanks
