i downloaded hibernate core 3.0.5 from this site, but i can not find the "org.hibernate.expression" package. so i checkout the "hibernate3" module source form sourceforge cvs. and run "ant" to build jar package; but when i run "ant", some errors occur. the following is the stack of this exceptions. it's look like the antlr application produce the wrong code...

How to Solve this problem? thx.

can you double check to see if there were any other errors? this looks more like a symptom rather than a cause.

one more thing - i'm pretty sure ant has it's own version of antlr, although I don't know if this is the problem.

1. The error message show the code cause this problem, it seems that antlr produce the wrong code....
2. I use the antlr jar file included in the lib dirctory of cvs source.
3. Another symptom is : when i change the grammar diretory files to those of version 3.0.5, the number of error change.
4. what can i do ...

just run build.bat then it will work

max:
thanks for your quickly reply, i try run "build.bat", it's the same problem ;(

well then i guess you dont have the exact same thing as what is in hibernate3 cvs

is/will there be nightly builds of hibernate 3?

i can't build hibernate with last ant (1.6.5) , too
build is fine with ant 1.6.3

just use the ant that is with hibernate - don't try to mix and match

I try the same code in another computer, to my suprise, it works ok... may be it's for the env. cause...
