java.lang.NoSuchMethodError: antlr.collections.AST.getLine()I

今天开发一个ssh项目时用myeclipse自动导入ssh的jar包报出以下错误：java.lang.NoSuchMethodError: antlr.collections.AST.getLine()Iorg.hibernate.hql.ast.HqlSqlWalker.generateNamedParameter(HqlSqlWalker.java:931)org.hibernate.hql.antlr.HqlSqlBaseWalker.parameter(HqlSqlBaseWalker.java:4909)org.hibernate.hql.antlr.HqlSqlBaseWalker.expr(HqlSqlBaseWalker.java:1404)org.hibernate.hql.antlr.HqlSqlBaseWalker.exprOrSubquery(HqlSqlBaseWalker.java:4383)org.hibernate.hql.antlr.HqlSqlBaseWalker.comparisonExpr(HqlSqlBaseWalker.java:3859)org.hibernate.hql.antlr.HqlSqlBaseWalker.logicalExpr(HqlSqlBaseWalker.java:1907)org.hibernate.hql.antlr.HqlSqlBaseWalker.whereClause(HqlSqlBaseWalker.java:822)org.hibernate.hql.antlr.HqlSqlBaseWalker.query(HqlSqlBaseWalker.java:608)org.hibernate.hql.antlr.HqlSqlBaseWalker.selectStatement(HqlSqlBaseWalker.java:292)org.hibernate.hql.antlr.HqlSqlBaseWalker.statement(HqlSqlBaseWalker.java:235)org.hibernate.hql.ast.QueryTranslatorImpl.analyze(QueryTranslatorImpl.java:254)org.hibernate.hql.ast.QueryTranslatorImpl.doCompile(QueryTranslatorImpl.java:185)org.hibernate.hql.ast.QueryTranslatorImpl.compile(QueryTranslatorImpl.java:136)org.hibernate.engine.query.HQLQueryPlan.(HQLQueryPlan.java:101)org.hibernate.engine.query.HQLQueryPlan.(HQLQueryPlan.java:80)org.hibernate.engine.query.QueryPlanCache.getHQLQueryPlan(QueryPlanCache.java:98)org.hibernate.impl.AbstractSessionImpl.getHQLQueryPlan(AbstractSessionImpl.java:156)org.hibernate.impl.AbstractSessionImpl.createQuery(AbstractSessionImpl.java:135)org.hibernate.impl.SessionImpl.createQuery(SessionImpl.java:1760)com.hnau.dao.UserDAOIMP.isReg(UserDAOIMP.java:56)com.hnau.action.UserAction.register(UserAction.java:41)sun.reflect.NativeMethodAccessorImpl.invoke0(Native

java.lang.NoSuchMethodError: antlr.collections.AST.getLine()I 的错误。这是因为在struts2自带的antlr-2.7.2.jar包的版本较低。需要换成antlr-2.7.6.jar。其实在项目中已经存在了antlr-2.7.6.jar这个包，现在唯一需要做的就是删除antlr-2.7.2.jar包。选择windows---preferences---在文本框中搜索struts 2(中间有空格)---选择struts 2---选择antlr-2.7.2.jar---Remove---OK。
