MarkLogic Samplestack installation issue (Execution failed for task ':dbTeardown')

Question

I'm trying to install Samplestack application for ML8.02 on OS X 10.10.3.

Following the instructions, everything goes well until the gulp once --browser=chrome step. This generates an Execution failed for task ':dbTeardown' error, leading to a "The Samplestack environment may not be properly configured." message.

According to the installation manual, this step needs to be called from the "local Samplestack repository root directory". Is this different from the "marklogic-samplestack directory" in previous steps? If so, where should I look?

Not knowing what to do, I used the marklogic-samplestack-master (root from downloaded zip) and got the following console error message. Any advice how to solve this?

Answer 1

Run into the same problem by following the guide and trying to skip Set up the Java middle tier and database tier with gradle step in order to configure Node.js-based middle tire only.

It can be seen from the log that gradle is used during First-Time Setup step. So I followed the first link above and as far as the second paragraph it goes

If you have already secured MarkLogic, you need to update gradle.properties with the admin credentials you used during the install and setup process.

Hope it helps.
