• Stacktrace (if present) provided
• Example that reproduces the problem uploaded to Github
• Full description of the issue provided (see below)

Steps to Reproduce

1. Create a fresh grails 4 application with grails create-app four-oh-nine
2. Add elasticsearchVersion stuff, compile dependency on the 3.0.0.M1 plugin and grails { pathingJar = true } in build.gradle
3. Add elasticsearch configuration to application.yml as per documentation, setting client.mode: local

Expected Behaviour

Application starts up with an internal elasticsearch instance.

Actual Behaviour

Environment Information

• Operating System: Windows 10
• Grails Version (if using Grails): 4.0.9
• JDK Version: 1.8.0

Example Application

After having using a plugin version with #74 fixed:

https://github.com/miq/grails-4-elasticsearch-startup-issue

[demon101]

I have same issue with grails 4.0.11
waiting for release
https://github.com/puneetbehl/elasticsearch-grails-plugin/pull/75/files

[purpleraven]

The local type not possible anymore. external ES instance with transport type should be used in dev

[miq]

@purpleraven Is there a good reason for that or does someone just have to implement a fix for reenabling the feature?

[purpleraven]

@miq https://grails-plugins.github.io/elasticsearch-grails-plugin/2.7.0.RC1/index.html

Embedded ES was removed and so there is no accurate possibility to run integration tests with ES, see here: https://discuss.elastic.co/t/in-memory-testing-with-resthighlevelclient/106196/6 . For now the integration tests are only working if a local elasticsearch version is running, which can be downloaded here: https://www.elastic.co/downloads/past-releases - please note that you’ve to use the same version like described in the above comments, so for now it is 6.8.2

[miq]

Ok, so as I see it only the documentation has to be changed to reflect the removal of the feature. It is ok for us to use a dockerized elastic search in development and testing.
