Dear all,

I am currently working on an Eclipse-Plugin that is built on top of the Hibernate Tools project. For example, I am using the following statements to get the AST of a named query:

try {
HqlParser parser = HqlParser.getInstance(statementString);
parser.statement();
} catch (RecognitionException | TokenStreamException e) {
e.printStackTrace();
}
AST statementAst = parser.getAST();

For this to work well with Hibernate Tools Version 4.0.0, I added bundle org.hibernate.eclipse.libs as required bundle to my plug-in configuration (which resolved to org.hibernate.eclipse.libs_4.0.0.Final-v20141016-1911-B82 so far).

However, I now updated to Hiberate Tools 4.0.1 (org.hibernate.eclipse.libs_4.0.1.Final-v20150324-2307-B95). The problem I have now is that the following imports cannot be resolved:
import antlr.RecognitionException;
import antlr.TokenStreamException;
import antlr.collections.AST;

The problem seems to arise from the fact, that in the new version's MANIFEST.MF, the antlr... packages are not exported and lib/hibernate/antlr-2.7.6.jar is not listed in the Bundle-ClassPath any more (I reformatted both MANIFEST.MFs, that you can find attached, to allow a convenient comparison). After manually adding the antlr-related entries to the new version's MANIFEST.MF, my code works pretty well again.

My question is thus:
(a) Do you consider this to be a bug in the realease of Hibernate Tools 4.0.1?
(b) If yes for (a): Do you have an idea when this issue could be solved?
(c) If no for (a): Which alternative solution would you suggest? I mean, manually editing the MANIFEST.MF of realeased plug-ins is not quite the best practice, is it? I tried to manally add antlr-2.7.6.jar as library to my project, which solved the compilation error, but yields a java.lang.ClassNotFoundException: antlr.LLkParser cannot be found by org.hibernate.eclipse.libs_4.0.1.Final-v20150324-2307-B95

Any advice?

Thanks!
Bastian
