[jira] [Closed] (TINKERPOP3-727) use of repeat() with in() throws
error
[ https://issues.apache.org/jira/browse/TINKERPOP3-727?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Daniel Kuppitz closed TINKERPOP3-727.
-------------------------------------
Resolution: Fixed
This is not a bug. {{in}} is a reserved keyword in Groovy, hence you have to add some verbosity, e.g.:
{code}
g.V(2).repeat(__.in()).times(1)
{code}
> use of repeat() with in() throws error

> Using gremlin-server-M9.
> When doing {{repeat(in())}} we get an error (maybe there's confusion around the in() predicate).
