Could you check if there is no ivy.xml in the parent directory that introduces such a loop? > StackOverflowError when using <extends> with no location specified > ------------------------------------------------------------------ > > Key: IVY-1347 > URL: https://issues.apache.org/jira/browse/IVY-1347 > Project: Ivy > Issue Type: Bug > Components: Core > Affects Versions: 2.3.0-RC1 > Reporter: Matt Hurne > Priority: Critical > > When using {{<extends>}} without specifying a {{location}}, we end up with a > {{StackOverflowError}}.
