[jbosstools-issues] [JBoss JIRA] (JBIDE-19792) antlr packages and lib not exported in Hibernate Tools 4.0.1

antlr packages and lib not exported in Hibernate Tools 4.0.1 ------------------------------------------------------------ Key: JBIDE-19792 URL: https://issues.redhat.com/browse/JBIDE-19792 Project: Tools (JBoss Tools) Issue Type: Bug Components: hibernate Affects Versions: 4.2.3.Final Environment: Eclipse Luna SR2 Reporter: Bastian Ulke Assignee: Koen Aers Priority: Major Fix For: 4.3.x Attachments: B82_MANIFEST.MF, B95_MANIFEST.MF 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: {code} try { HqlParser parser = HqlParser.getInstance(statementString); parser.statement(); } catch (RecognitionException | TokenStreamException e) { e.printStackTrace(); } AST statementAst = parser.getAST(); {code} 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. I agree, that internal libraries should generally not be exported. However, org.hibernate.hql.ast.HqlParser is exported -- so why not its prerequesites? (By the way, I'd be fine with integrating another library into my project. However, 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.)
