I install vietnamese-analysis for Elasticsearch 7.12.1.

But when I restart Elasticsearch, I get the following error:

Looking at the plugin repository it doesn't look like it is compatible with your version of Elasticsearch. How did you manage to install it?

I clone code from

git clone [GitHub - duydo/elasticsearch-analysis-vietnamese: Vietnamese Analysis Plugin for Elasticsearch](https://github.com/duydo/elasticsearch-analysis-vietnamese.git)

Then i changed version to 7.12.1. Because my Elasticsearch version is 7.12.1

```auto
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch-analysis-vietnamese</artifactId>
<version>7.12.1</version>

```
