Building antlr 4.1: no such property or can't access: org.antlr.tool.Grammar.indirectDelegates

[henrik sorensen]

Esteemed group,

I have had a version of ANTLR v4.1 for quite some time in my Eclipse workspace.

Now when I try to build this version using build.xml, the following error happens.

How can I decipher this?

The code hasnt changed since my last build, but I have upgraded Eclipse since.

I can't easily upgrade to latest ANTLR so any help greatly appreciated.
