----------------------------
Resolution: Fixed
> Update Flink build instruction to deprecate Java 8 instead of requiring Java
> 11
> -------------------------------------------------------------------------------
>
> Key: FLINK-30501
> URL: https://issues.apache.org/jira/browse/FLINK-30501
> Project: Flink
> Issue Type: Improvement
> Components: Build System / CI
> Reporter: Dong Lin
> Assignee: Dong Lin
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.17.0
>
>
> Flink 1.15 and later versions require at least Java 11 to build from sources
> [1], whereas the pom.xml specifies the source/target is 1.8. This
> inconsistency confuses users.
> As mentioned in the FLINK-25247 title, the goal of that ticket is to "Inform
> users about deprecation". It will be better to inform users that "Java 8 is
> deprecated" instead of saying "Fink requires at least Java 11 to build", so
> that users have the right information to make the right choice for themselves.
> Also note that Flink community is regularly running flink-ml benchmark for
> both Java 8 and Java 11 [2], which suggests that we are practically ensuring
> Java 8 is supported.
