Left join operation performed in querydsl gives 'path expected error in querydsl'

问题

Here is my code:

QueryFactory.selectFrom(table1)
  .leftJoin(table2).on(table1.id.eq(table2.id)).fetch();

When I execute the below code in querydsl I get the following error:

08:08:54.866 ERROR o.h.h.i.a.ErrorCounter - Path expected for join! 08:08:54.870 ERROR o.h.h.i.a.ErrorCounter - Path expected for join! antlr.SemanticException: Path expected for join! at org.hibernate.hql.internal.ast.HqlSqlWalker.createFromJoinElement(HqlSqlWalker.java:369) ~[hibernate-core-4.2.1.Final.jar:4.2.1.Final]
