While building Docker file, installation of elasticsearch-plugin fails with "Error: Could not find or load main class org.elasticsearch.tools.launchers.JavaVersionChecker". It fails for ElasticSearch 6.4.x and 6.5.x versions.
I have seen previous links and blogs mentioned in the below links.
- Error: Could not find or load main class org.elasticsearch.tools.JavaVersionChecker
- Could not find or load main class org.elasticsearch.tools.launchers.JavaVersionChecker
- https://github.com/elastic/elasticsearch/issues/27599
According to the above links, have changed the owner given the necessary permissions and running as non-root user. VM and jvm are both 64 bit.
The same Docker file we were using it for 5.6,6.2 and 6.3 versions of ElasticSearch. It fails for 6.4 and 6.5 versions of ElasticSearch. DockerFile is below.
