prometheus-exporter requires Java 16 Error

[alexblue46]

When installing elasticsearch-prometheus-exporter version 7.16.3.0, I get this error: java.lang.IllegalStateException: prometheus-exporter requires Java 16:, your system: 8. Is it possible that this prometheus exporter may be made available for use with either Java 8 or 11?

+1 just realized I'm using version 8 of java

[ilunie]

I fix the issue by changing the java_home before running the installation

@ilunie Were you able to install it with Java 8 or 11?

@alexblue46 we've used the Java 16 embedded in ES7 install. That's what @ilunie means by changing JAVA_HOME value, to point at the JVM shipped with ES7.

[mindw]

ES 8.x.x requires JVM 17 - elastic/elasticsearch#79873 . The CI builds it with 16 - to build with something else one needs to build it locally.
